Too Big For Most Locos & Burnt Out After 1 Day | Hornby's New HM7000

[@olivermiles6858]

Sam, regarding the functions, you don’t need to import a map. You can go to the function tab and setup your functions pages yourself. Click into each function and you can edit the name, icon, function number etc. You can also drag and drop the functions on the grid to rearrange.

[@SamsTrains]

Thanks Oliver, I'll have a look at that... would be much better if the functions were just there to push by default, as with every other controller! Thanks for watching, Sam :)

[@bear470]

My local model railroad club here in the US has their layout set up with the dcc system through a secure wifi system to use both dcc controllers and smartphones. I used my phone to control my personal rivarossi allegheny, and though there were a couple of hiccups, it worked fairly well

[@42cerberus]

There are 2 major drawbacks with this system that I can see. You've touched on the first one with the size but it appears that Hornby have designed the decoder round their own locos and only their own. That means, as you have seen, the chances of it fitting anyone else's are slim. Secondly, as this is a Hornby system, they control the sound files you can upload. Got a Dapol 59? Want sound for it? Sorry, not a Hornby model so you aren't getting it! Got a Bachmann 66? Want sound? Sorry but we designed the decoder so it won't fit in anyone else's models. Hornby seem to exist to support their own models and get you to buy only those.

[@SamsTrains]

Thanks for sharing! Yes I'd say you're right on the first point... and only the TT locos at that, as I can't recall having any Hornby OO locos with a Next18 socket. Agreed on Hornby's control of the sound files... but they stand to sell more decoders if they give some customisability to their customers... can't see what they've got to lose by not doing that! Thanks for watching, Sam :)

[@mikewoods4177]

Sam how long will they remain free to download? Other developers get market penetration then start to charge. There must be a cost to Hornby to record the sound files. So how long will they continue to subsidise modellers. Just asking!

[@chestertonroad4565]

Who's to say they won't release further sound files for non-Hornby locos? It seems logical that they would start with files for their own locos. Why would the decoder not fit in a Bachmann 66? There's loads of room in them.

[@mikeking2539]

@@mikewoods4177 That's a very good point!

[@speleokeir]

I believe they are concentrating on sound files for their own locos first, which is fair enough. Once they've done that then it would be good if they considered adding profiles for other locos or provided an option for people to add their own sound files. Whether that will happen I don't know, I guess it depends on whether there's an benefit to Hornby of doing so.

[@scotmcmanus9401]

Another good video, Sam. I am surprised that you did not start with the TT model or a recent Hornby one. I thought it was pretty obvious that Hornby designed this system with their locos in mind. Same as Bachmann and Dapol do with their chips although there will be some useful crossover. It will be more interesting to see if the other decoder manufacturers start to make compatible decoders. I think this looks like a great system with loads of potential.

[@BoaFilmsPlc]

Scot, as far as I know, the only other firm that makes decoders that operate with bluetooth is Soundtraxx in the US.They released their new Blu-nami decoders at the end of 2022. I do like the concept & hope Hornby won't take as long as Soundtraxx are to release the app for Android users.

[@simonturner5450]

Interesting and informative review Sam. One angle that you didn’t mention is that, certainly an iPhone, is limited to 3 to 4 Bluetooth live connections at one time. This might be a deal breaker for anyone who wants to double head a couple of trains simultaneously on their layout.

[@andrewtongue7084]

& that's the point, Simon, iPhone are notorious for being unilateral - as are Hornby....unless the latter have a change of heart, I cannot see this getting off the ground, because it's (already) a self-limiting exercise....

[@wapphigh5250]

Hi Sam - ignore the negative comments. I thought this review was great! You are one of the most respected reviewers on youtube and had every right to call out some of these issues. Keep up the great work. This sort of review is why I come back to your channel and has (and will save me) many hrs and dollars building my collection. Respect. Wapp.

[@HighFell]

Why would any right thinking person ever think a review by an uneducated person was good? Sam doesn’t understand the technology behind this system, that’s pretty clear. The evidence is in his own video. You can convince yourself that an uneducated person telling you what to think in contradiction of the truth is a good thing or it could be you are in denial of reality

[@mkaustralia7136]

Sam has more education on these things than I can get by reading the selling brochures and the positive reviews by the various press and KZbinrs. If I have to read the papers with the items plus a 200 page user guide and risk the thing burning out as at least two have, my commercial sense says wait and see. If I add to that Hornby’s approach to the hobby, I am uncomfortable investing a few thousand pounds into converting my DCC ready locos to this system. I was astounded by the vehemence of the model shops I contacted to buy some Hornby product recently. Sam is a fan boy for Hornby by comparison. I then tried buying direct from Hornby, but individual postage for each coach in a rake of 4 wheelers and their dismissive reply made me realise just how much brand equity had been destroyed by the current managers. That leads to loss of trust, so that plus the issues above means I am not going to rely on Hornby for the lifeline to operate my models.

[@wapphigh5250]

@@mkaustralia7136 Are you saying you've tried 2 HM Bluetooth chips and they have burnt out already?! What were the circumstances? Thanks

Local Aussie retail Hornby prices & availability are influenced by exclusive distributor Southern Model Supplies. Getting anything sent from the UK or Europe is often expensive.

[@ivovanzon164]

The only reason that the decoders won't fit is that the pcb size is dictated by the antenna. If a version is offered with a separate antenna pcb the size issue would be solved

It doesn't beat the click and turn of a good controller Knob but it's great that people have more choice.

[@TheRip72]

Real trains are hard to get going & take a lot of planning to stop. Having instant response at the turn of a knob is a huge cheat around this. So if you like driving trains, it beats a turn of a knob hands down. It depends on your preference doesn't it?

​@TheRip72 I found it wasn't that hard to bring a peak to a stand at Chesterfield with 12 mk2s behind, But I kinda know what you mean.

[@krazytroutcatcher]

I like the idea of Bluetooth, it seems to have potential. Hornby will have to look at resizing the board, or maybe an extension lead so the Bluetooth board can be located elsewhere? A dummy board would be good too, so we could try it for fit before purchase, to make sure we can fit them to existing locos.

[@wapphigh5250]

Awesome idea! It's really hard to return a DCC chip after purchase as retailers often think you've messed around with it already

[@SamsTrains]

Yeah I do too - and while it worked this was really great to use! An extension lead would have helped a lot - reckon this could have fit into a few of the locos I tried if it had one! Thanks for watching, Sam :)

​@@SamsTrains in the hornby livestream today they even said it could be fitted into a coupled wagon behind the loco. Not sure how you would connect it up though.

@@russcole5685 , did you watch all of the video, he went down 2 floors in his house and it still worked.

[@clementmatchett]

As I have written elsewhere, I had the same problem with loading the sound profiles for Flying Scotsman. I think the Hornby server became overwhelmed, because when I tried it at 6am one morning, it worked fine. These 18 pin decoders are really intended for locos designed for 18 pin, which so far is a category which is largely confined to TT120 ones. But I think the new Dublo Merchant Navy is either 18 or 21 pin, and I presume the new decoders will fit it. I haven’t ventured into trying the 8 pin decoders so as to convert my 00 locos to TXS sound and Bluetooth control, but again, I assume the Hornby 8 pin TXS decoders will fit at least the majority of Hornby locos, and perhaps some other brands, and the pictures show that some components are on a separate harness. As to burning out, I have been running three TT120 locos on this system without problems, using the Hornby 4 amp transformer, which I believe has short circuit protection? Are you sure your Powercab has? It looks like space junk from Apollo 13!

[@1234mattyman]

Regarding the power loss and how long it takes to come back on is because it has to reconnect to Bluetooth as Bluetooth sometimes is slow to connect. This should use WiFi or WiFi direct which would be faster to connect. Bluetooth is slow and always will be. Great video as usual.

[@Stettafire]

Bluetooth also has much less bandwidth then WiFi, which is why even things like Bluetooth headphones often cut out. There is particularly a known problem with Bluetooth on windows because of the bandwidth. I really don't think people should be using Bluetooth for things that require complex controls. Even most gaming controllers use either USB or radio signals

[@1234mattyman]

that is so true, that's why i suggested this should use Wi-Fi or a USB dongle or something with more bandwidth than Bluetooth. @@Stettafire

[@1maico1]

Most of the ESU and Zimo non-sound decoders I've bought have clear shrink wrap to protect them. Hornby should consider that. Everyone should use an insulated screwdriver to avoid static.

[@cuebj]

And an earthing wristband, just like working with computer parts

[@kiwitrainguy]

The ESU decoders that are 8 pin ones have the shrink wrap but the 21 pin ones are bare.

[@steveb2985]

In the past I have dcc'd old locos with a pre wired 8 pin socket which you can then place anywhere in the loco body .I'm sure these are available for 6,21 and next 18. All it needs is a male to female extension with a 15cm ribbon in-between ,then you could place the chip elsewhere. Maybe someone will bring it to market.

[@TheRip72]

I have never seen a 21-pin, Plux or Next decoder with wires. The whole point is that they are tidier with no wires hanging off & should be a standard size which should plug straight in. It is worth pointing out that the only Hornby 18 pin loco Sam tried was the TT120 Scotsman. The others were from different manufacturers.

[@rogerwindsor2130]

There are already adapters Availiable from dcc concepts

[@steveb2985]

Yes I get the point but if it doesn't fit then an adapter is the next best thing,thanks Roger

[@DangerAngelous]

If these chips didn’t become self-fried and only come in large, these would be the perfect gateway for people like me on the fence between old reliable DC and ultra precise but previously expensive DCC. Very much appreciate as usual your thorough testing of absolutely everything with these!

[@bazza3643]

Hi Sam, I’ve enjoyed this very formative video. I noted your comment at the end, about the decoder burning out. Over the past 25 years or so, I have installed a range of decoders in my models, including TCS, Lenz, Bachmann, Hornby, NCE and ESU. Out of all these various decoders, the only decoders that stopped working for me have been the Hornby decoders, which do not seem to last the distance.

[@derronbailey9332]

Great review Sam. Although I don't use or enjoy DCC much, I can definitely see the benefits to this system. As it's the first if it's kind it is understandable that there will be issues, but hopefully this will be a good first step for Hornby and other manufacturers to hopefully get the ball rolling, and bringing this hobby into a new age.

[@johnwalkley6746]

As has Lego, but in a much simpler form.

[@bulleidboy1]

I'm running HM7000 through an iPhone and Hornby Elite - the whole system works fine - no problems at all. It's very early days in what looks like a brilliant system. Sam - it might be worth doing a bit more homework and reading the manual before making some of your comments.

[@melchestermodelrailway]

That was quite a bombshell at the end Sam, but thanks for being so diligent in your reviews. I hear some people say "Sam has bad luck with his loco's", but I think it's only because you put models through their paces and actually discover faults overlooked by others.

[@tonyburgess7773]

I would be very hesitant to carry out a power interruption test the way Sam did. Switching power off and then on again is not the same as going through dead rail - it quite probably hits the decoder with a power spike..

[@StormmyStormmy]

Hi Sam, great honest review, this system looks very good, a lot of modellers use TTs decoders in Bachmann locos with great results, maybe Bachmann should invest and produce their own bluetooth system, going on what they charge for their items it would probably cost a kidney to buy one, hopefully somebody will produce a generic system for all manufacturers to use bluetooth. I'm a big Accurascale fan, maybe they will bring out a bluetooth system in the coming years. By the way what burn out after one day?

[@10C45E]

it's at the very end of the video

[@GaryNumeroUno]

"Tight is fine... as long as it fits!" No truer words have been spoken mukka. 😅

[@aleopardstail]

with luck the main benefit from this system will be to bring the prices of other decoders down to reasonably similar levels, the idea is a good one - even if the bluetooth stuff is only used for configuration of sound etc and not really running. that said I can see a decent potential for these in "DCC Trainset" boxes, a prechipped sound locomotive with control over an app and not the "Select" controller could I think do pretty well issue with burning out.. I guess this comes down to three things: 1. how common is it? 2. what causes it? (is it a design fault or is it poor testing causing the problem?) 3. how Hornby react to it when it happens if the answers are "rare", "???" and "they replace them easily" its probably fine until they sort it out, new tech will have issues but if this is a case of the decoders are fragile in some way they are not really fit for purpose, if its a manufacturing and testing issue hopefully it can be resolved. good review though as always, nice to see these things approached from basically a "does this work out of the box?" approach and not saying it worked but hiding all the fiddling needed

[@georgemartin408]

It’s very early days for a completely new system. Hornby freely admit it’s a case of constant development. They also have enough small locos of their own to realise that they will need to solve the chip size issue.

[@TheRip72]

They do need t shrink their decoders, but do they make any small OO tanks with an 18 pin socket? All those Sam tried were from other manufacturers.

[@keiththesoundguy2890]

It’s a case of each to their own with these. I won’t be using them having tried a 21~pin version because there is no finesse in the motor control. The sound as I perceive it is just the same as TTS in both the sound samples themselves and BEHAVIOUR of the sound. The chuffs are not spaced proportionally with the speed of the wheels - they simply play at certain fixed intervals so you can hear it ‘step up’ to the next set when the physical speed rises, rather than being gradual. Thus, you will never have the chuffs in sync with the wheels throughout the speed range. The extra cost of Zion and ESU is worth it to me because I can load my own sounds. Also, I could not tolerate such a long recovery time from a power outage. Thanks for the all the videos you put out.

[@stillstanding123]

Good review. Like all new products pushing into new ground there will be a learning curve and teething problems for both manufacturer and operator. Adequate product testing and beta customer feedback should have minimised these and lead to product updates. I am sure Hornby will bring out software upgrades and improvements. 🤞

[@pauleddleston2817]

Just a note on next18 burn out. Handling these decoders has to be done carefully and making sure that you are earthed and don`t get the fingers touching across joints etc and depositing body oils which can short out the chip. The amount of times that decoder was tried in different locos ... tbh ... not surprised it blew. If handling instructions are provided (poor if not) they should be followed.

[@SamsTrains]

I was very careful with the handling, and if it'd fit into the first loco I tried, I wouldn't have been handling it as much. I didn't see any handling instructions. The decoder worked all day once fitted into the Scotsman. Not sure how body oils could short out the decoder over night, at least not at these low voltages, but I'm no expert! Thanks for watching, Sam :)

[@davidf2281]

It's not possible to short components with "body oils" and it's also very unlikely that unearthed handling will do any damage. This is why manufacturers are happy to sell these bare boards -- if normal handling killed them the return rates would bankrupt them.

[@firestarspelt]

ive installed dcc in over 50 locos never have i killed a decoder by static and body oils aint going to do anything to a decoder

[@DJ_K666]

We were controlling our layout at Warley with smart phones, using a Raspberry Pi through a Sprog and with JMRI installed its all NRMA compliant and we had sound. Personally i think this is a relatively new system so there will be issues and certainly the size could be fixed although adding bluetooth elements to sound elements means they have to go somewhere and that means a bigger chip. I'm not sure whether that means hornby locos are made with it in mind in future or not but certainly i can see other manufavturers scrambling to keep up. I believe there are other bluetooth chips in the US but it'll become more widespread over the next few years.

[@henriknilsson7851]

I have a Hornby Coronation 8P that needs a chip. Maybe a Hornby Mallard. If they make this as an 8pin decoder I might give this a try.

[@_Zekken]

My assumption for the size is that they were designed with Hornby locomotives in mind, since its a hornby system. I bet as they continue to improve the product they'll be able to shrink the PCB size to fit in more locos. With the cutting out and restarting under bluetooth, I bet its because it takes a few seconds for the bluetooth module to restart itself, and then reconnect to the tablet. Thats more a limitation with the bluetooth system in itself than with the decoder or controller, so I dont think theres much Hornby can do about it. You'll definitely want that stay alive battery to avoid those issues.

@@johnhughes3796 I do have a gaguemaster DCC controller

[@TheYancydog]

Sam- My guess as to why you lose control after loss of power under bluetooth is that when the power goes, you lose bluetooth comms to the tablet. It would take about that amount of time to recover bluetooth comm and regain control of the loco. You can see this type of lag when you drop other bluetooth devices and try to recover comms to them.

[@NWRJ_WStudios]

I think Sam Hornby designed these decoder to be fitted into there own locomotive, and not other manufacturers. Cheers Jasper & Willow

[@Robutube1]

If you're correct, it is a poor marketing decision because it would restrict sales.

[@mkaustralia7136]

Agree as Sam said, Sound Fitted would be dead as an option as even at a reduced price it would still not come with the smart phone app interface which seems superior to other DCC controllers. Everyone else would have to improve, but in the meantime there are thousands of DCC ready locos which could be chipped if the owners desired.

[@TheScotsalan]

I think its a great idea. Dont know why its taken so long. I reckon too, once its on software, it opens up a whole new world. Want a full auto layout ? Forget rfid chips and readers etc, just mount a camera in your rafters and add vision software stuff to the app ? Tap on a location on your cam display, and say what you want the train to do when it gets there. Stopping at a station as an example 👍

[@BoaFilmsPlc]

Hi Sam, I feel, as a DCC sound person, a few errors in your assessment of the Hornby decoder. 1) "Why would you buy from another decoder maker?" If you look at the major brands, ESU & Zimo you'll find they make various sizes of decoders to fit any size of loco. As you found with the Next18, only your D11 & TT A1 would accept it. The size of the decoder was a major issue. Add in the speaker plus a keep alive and you might find things won't fit anywhere. 2) Expecting to fit them in non-Hornby products or locos designed before these decoders were.. Again this is why I will be wary about using them over say a Zimo or ESU simply as Hornby have used a one-size-fits-all mentality. 3) Most ESU & Zimo decoders can play up to 8 sounds at a time. The new MS decoders from Zimo use 16 bit quality. 4) Soundtrax in the US released a similar Bluetooth system back last year. To date, there is still no Android app available, will Hornby be the same? Not everyone worships at the Church of the Bitten fruit! 5) Do you truly think Hornby will create sound set ups for competitor's locos? I highly doubt it to be honest. This, like the TT:120 are Hornby's own. I own a Roco Z21, the only function set ups i can get are either Roco or Fleischmann models from the last 10 years. I do like the idea of the decoders, but the size, the lack of Android app & the tie-in to 1 manufacturer puts me off buying them. Keep up the great work.

[@wapphigh5250]

Excellent comments

[@SamsTrains]

Thanks for sharing! Yes the size of these (particularly the next18 one) is definitely a big con. As for non-Hornby locos... very few Hornby locos have Next18 sockets... the two TT locos I have are the only ones as far as I know... so I assumed I might have been able to find a loco that could accommodate them... but no luck. No, I don't expect Hornby to create sound profiles for competitor's locos, nor did I say I thought they would. What would be nice would be the option to customise/create your own profiles within the app... that's what I said! Agreed, those are very offputting! Thanks for watching, Sam :)

[@markedwards1511]

Very interesting review Sam! I assume it's also possible when using a DC power input, that you don't need to remove any other non-DCC Locomotives from your layout as long as you have isolated sections of track? Therefore you don't need to convert all your loco's at once, but as your budget allows for and still run both. It must be possible to station your Bluetooth loco (with sound off) and bring a DC loco out of a isolated section to run on the same track as the stationary engine. No more worries about damaging your locomotives!

[@YTBCONE]

I think it's brilliant you will need to measure the area your putting it but other than that it's amazing especially for the price!

[@mikeking2539]

Another issue with this system for some of us, like you said at the start of the video is not all of us have a "Smart" device. Ok I have a phone that I could use it on, but the drawback with using a phone, is the size of the screen. So not something I would want to try and use.

[@rogertarring6165]

There are lots of cheap Android tablets around which would be a cheaper option than a phone and have larger screens.

[@Decrepit_biker]

The brake function is useful as you can set the chip up such that you can shut off the throttle and the engine will continue on its own simulated momentum. You can then stop the engine by pressing brake EXACTLY as you would on a real locomotive. I also suspect that you turning the controller off and on may be causing a spike of some kind and confusing the chip. Is the controller a feedback type, if so due to the way they work they can confuse electronic things. Would be more representative to lift the loco clear of the track and leave the power steady.

[@SamsTrains]

No it isn’t a feedback controller - the switch just disconnects the power, in the same way that a cut out would!

[@Decrepit_biker]

​@@SamsTrains worth a try to see if there's a difference, I have had electronic issues caused by switches in the past in industrial CNC machinery. Poor or burned contacts in the switch caused arcing and upset the electronic item "reading" that particular switch.

[@muir8009]

Just having a look at the tomix controller I've got and that after throttle off has continuous momentum, then brake applications in stages as per prototype enables different % drops depending on the brake applications. They're quite an art to use if you're used to the typical dcc/analogue user experience.

[@cirseltoo]

It is about seven or eight years since I saw the layout "Holcombe Brook and Tottington" at Wigan show with the locos all sound fitted and the layout being controlled by smart phones. The problem with the HM7000 is that the steam sound files STILL can't be synchronised to the wheels, which is basically is a kids toy. Serious modellers still need to pay about £100 for decent sound.

[@Elvinley]

I had a few issues with TTS chips burning out a few years ago. Hope these aren't as delicate as they are. The more expensive decoders have some level of protection.

[@stormbowman7148]

The 21 pin decoder size is within the limits of the NEM specification of the MTC21. This means that it will fit all locomotives with a MTC21 pin socket. This should cover 99% of all models on the market with the 21 pin socket. You might be able to fit the Next18 non sound version. It is much smaller decoder.

[@kiwitrainguy]

NEM 662 covers the specs for the Next18 decoders and the dimensions for sound decoders are bigger than the ones for non-sound decoders.

[@dunnyraildunnybahn5481]

The reason it did not work, at the end of the load of profile the app showed the shunter being lifted off the track. This resets the decoder to make it work, all shown in the tutorial Sam. When you switched off the system it had the same effect so well worthwhile to have a section switch on a decoder track and watch out for that lifting the loco off the track on the app. It is used a couple of times in the setup process.

[@SamsTrains]

No no, I cycled power to the decoder whenever asked to - I can read haha!! ;D Thanks for watching - Sam :)

[@alantoms3263]

Nice little review Sam. Is there any chance Hornby have got the exhaust beats right, or is that aspect stuffed as normal? This is THE reason I can never consider DCC Sound - I need a really expensive DCC-S chip to permit correct beats / chuffs. All other sounds are likeable gimmicks - the exhaust is what's important on a steam locomotive. Al.

[@Elvinley]

Absolutely true!

[@rich81090]

I generally fit stay a lives to all my locos, I normally use dcc concepts as you don’t have to be an expert soldier to attach to stay alive but size is certainly going to be a issue. Also in a garden layout 30ft probably isn’t that far, range would be something I would like to test further.

[@russellbenton2987]

I think a major innovation is that you can run DCC Sound on what would normally be a DC layout simply by turning controller to max and using the app to control . So those of us who don’t want to go full DCC but would like to dabble with the occasional sound loco are catered for

[@SamsTrains]

Absolutely - that aspect really is a game changer isn’t it??

[@OlivierGabin]

@@SamsTrains It is. Or, I would rather say, it would be once someone else than Hornby does this, DCC on BT.

[@Cliff-hk9tc]

Bluetooth is a standard that anyone can follow. Hornby must be running a proprietary protocol on top of the Bluetooth to control the DCC decoder. It is this protocol, or something similar, that needs to be standardized and made available to all manufacturers. Hornby should do the honorable thing and allow NMRA to make the Hornby protocol into a, royalty free, standard that anyone can follow. This is what Lenz did when they released their DCC protocol to NMRA and that was hugely beneficial to the industry.

[@phil36310]

Hi Sam, By now there are many reviews on this new Hornby TXS - HM DCC system. What strikes me every time is the lack of insight for no one has consulted the 'Full Reference Manual' - let alone the 'Quick Start Guide'. So a lot of guessing and supposing and even pure nonsense (on a particular well known channel ) etc. I do recomment everyone to consult this very well written and well explained manual. It's a must to understand the 'system' - for help setting up - fine tune and then enjoy any loco you have equipped with a TXS decoder. It's only normal that Hornby first provides this system for their own stock of locomotives but according to the latest life show other non-Hornby sounds will be released in the future. Downloading your own sound is excluded - understandable. Besides if you want to do this with systems as ESU and the like you need a serious investment in hardware to be able to do so. And yet not all sounds are free ! The problem with the size of the decoder can be solved using a cable Next 18 male / female or you could try to loosen the support board from the chassis. And hard-wiring is always a solution with the good old 8-pin version.. A con ? One need to be 'inventive' as we did and do with 'ready to repair' stock. What no one mentions is that the chuff rate for steam locomotives is NOT synchronized. Explained in the 'Manual'. With all the high tech and possibilities of this new decoder this is a real let down. So high end ( read expensive ) decoders from the competition will remain for the 'purists' of fidelity to the prototype. In the end you can't get a Lexus for the price of a 'deux chevaux'. But let's give Hornby and Hammond Morgan the credit to bring a system to the market with a lot of bells and whistles for a very reasonable price and without the need of expensive Command Stations that are outdated anyway. DCC with BLE is indeed 'the' future'. And this is only the start... Cheers, Filip

I've just answered my own question by downloading the hornby manual. It seems the board is longer and wider than the standard. Strictly speaking it is therefore incorrect for Hornby to call it Next18 compliant/ compatible.

If the hornby servers stop working it will only stop you downloading new sounds it will not stop your already downloaded sounds etc from working on the app via bluetooth. If hornby did stut down servers the a group could potentially get hornby approval to set up alternative server. The 7000 sound decoders are a nice enough upgrade on the TTS decoder from the sound side that even without the bluetooth function and a good price. If the bluetooth ever becomes unusable via the hornby app then there are relatively easy ways to use engine driver app to bluetooth control the loco and its sounds.

[@RichardBrooklyn]

@@Cloudman572 this works until it doesn't. Look longer term. Sure you can use the app with no Internet today... Do we know how long the login lasts for without the app "phoning home"? A week? A month? Six months? Forever? Hopefully forever, but we can't verify that. Let's go beyond that for a moment... Your iOS device breaks because you dropped it (clumsy you), or maybe the battery gave out, whatever. No biggie. You go get a new one... Reinstall the app. Uh-oh, Hornby went bust/dropped support today for whatever reason. Now you can't sign in because the server is switched off. The equipment you own is now useless because it's all stuck in Bluetooth mode with no way to change it to DCC mode because you can't login. Worse still, you can't even re-pair your decoder to the new device (even if you could login) as you need to get a one time code from customer services, who can no longer help you because Hornby has dropped support/gone bust. Hornby could have just put a small reset button on the device itself. They deliberately chose not to, to force you into relying on them. That's a real shame as you purchased some sound packs you can no longer download (you didn't think all the new sounds would always be free, did you?) If Google can drop services on a whim, then Hornby can do it as well. The whole thing has been heavily architectured to *rely* on Hornby at every step of the way. Which means we need to rely on Hornby to always act in good faith and to stay in business forever for this stuff to work. Are we expecting Hornby to support this thing and run it at a loss forever and a day? 5 years maybe. 15 years... Probably not. At some point, these servers WILL be switched off. Worse still, the Bluetooth protocol they are using is not open. It's all locked down to Hornby only. One vendor, one choice. Imagine if DCC was designed like this... If it were open protocols it would matter a whole lot less. Even worse is that Hornby have very clearly ignored the next18 standards and made the boards too large. Again, another deliberate move by them to lock you in. I'll probably still buy one, admittedly. But I'll be keeping my eyes open for trouble on the horizon and I'll probably do the day-to-day stuff with DCC. Go in with your eyes open to it: vendor lock in can be very expensive.

I would imagine the delay to restart when the power is cut can also be attributed to the fact it's got to re-establish the bluetooth link also. So yes, the power bank they sell is the way to go to avoid it, or any other stay-alive capacitor. With regards to the size, and the fact that it seems to be aimed for their own newer models only, I think they are shooting themselves in the foot there. Hornby should know that will cause a lot of negativity towards them, I cannot see too many people wanting to use the system if it's not going to fit half of their loco's. And if Hornby feel this will make people buy more of their locos, that is just not going to happen, with maybe the exception being a child's train set. Hornby should be grown up enough to know that modellers will have a range of different makes of locos. If they really want the bluetooth system to take off, they need to make sure it fits other peoples locos.

[@davissampson3991]

Sam, I think your expectation that this HM7000 will fit in a non-Hornby locomotive is unreasonable. The ‘other’ manufacturers never accepted a ‘requirement’ to accommodate the HM7000 decoder form factor that was unknown until a few days ago. I think a meaningful evaluation would have been to install it into a DCC-ready (I.e., 21-pin or Next18) Hornby locomotive for which a sound file has already been made available. If it fits in another manufacturer’s loco, we’ll, that’s great, but that loco was not designed to accommodate it.

[@SamsTrains]

It’s not unreasonable - DCC is a standard, and the box clearly stated that the decoder complies to all NMRA standards, The NMRA specifies standard decoder sizes, and this decoder exceeded them. So no, I wasn’t unreasonable, and I stand by my criticism of it for that oversight. The ‘other’ manufacturers designed their locos to adhere to the standards. Had Hornby done the same with their decoder, then all would have been fine.

[@timpeel4386]

Informative video. 1. If many decoders fail I'm sure it will be all over the forums, and it is the first batch so not unusual. 2. I have two small steam trains, shunters, and looking under the case they would both need a socket adding (box marked as DCC ready) and only room for a non-sound decoder. 3. The IOS version only works with iPads and iPhones manufactured in the last 5 years. I am waiting to see if the Android version works before ordering a decoder, as I am still only DC The take-up of this will only sell if the app is excellent and the decoders are as good as other manufacturers.

I am yet to invest in DCC system and I was hoping HM7000 would mean I would not need to, but I don't think this is the case. Whilst this offering could be regarded as a step change, it is still based on bluetooth technology which is not new. I fully expect another manufacturer to offer something similar in the future and it will probably be better and compatible with a wider range of brands.

They do seem tempting for larger scale outdoor layouts who use battery power. If you get a cheap dcc ready loco of ebay, take out the electric’s and wire up a 9v or similar battery to the wires where the pickups usually attach thus removing the cutting out issue, plus size won't be an issue due to the scale being larger. Wire up a motor, plug in the chip and you're good to go. A whole battery operated train with sound for £60 where it would normally cost you way over £100.

I'm sorry you had so much grief with yours. I fitted one to my TT Scotsman and it worked straight away. I didn't even have to chose the sound profile - it just did it all automatically and with a cycling of power (lifting the loco on and off the track) it worked faultlessly. I only have a few bits of TT track and of course drove it off the end of it at one point. A quick nudge back on and it picked up almost instantly and was away. As for it cooking itself, that's worrying. I'm guessing this, and perhaps the other issues could be down to power line issues (too much, too little, being unhappy with voltage/current profiles) but it's worryingly inconsistent from what you've shown and it should never bake itself as a fault condition. My set up was literally a HM6000 power supply, straight into the TT120 DCC track connector and it just worked. I guess it could be that temperamental in it's power requirements that it HAS to have Hornby kit, but that doesn't seem right. I will have to update if I have any problems like this crop up.

It would not fit any of my small locos that I want sound and the power bank for. I to thought this was ridiculous, however I will put it away as it may come in handy in the future, I guess. I also have 8pin and 21 pin decoders. I spent hours and hours over two days trying to get one of the 8 pin decoders into a Bachmann 08 shunter and the decoder lost its sound, then would not run the train and then would not fit in the train anyway. I sent the decoder back thinking it had an issue. I then spent many hours over 2 days with the 21-pin decoder as the same happened with the sound going missing when I tried to add a new sound profile. I brought a Dapol class 73 for the decoder to fit in as I had seen someone else fit the decoder ok earlier in the week on KZbin. I eventually realised that I was not wating long enough once the sound files had downloaded to the decoder for them to be installed correctly so the sounds were just wiped out. There is reference to waiting 5 or 60 seconds depending on whether you have a power bank fitted when you take the train off the track, but it mentioned nothing about inpatient excited users should let the sound download do its thing (walk off make a cup of tea etc) then recycle the power and import the sound mapping. I have asked for the 8-pin decoder back from the shop as I am 100% sure the same thing happened with that one. At least the 21-pin decoder is working great now on both blue tooth and DCC NCE Cab so I am hoping the future dongle will bring even more functionality to the rest of the fleet. Thanks :)

Dear Sam. The delay after the power cut happens only when in blue thooth mode because that is part of the blue thooth standard. You never notice, but when you start a blue tooth connection it always takes 10 seconds. But you are busy with other things then. Sound files should be comparable to all other DCC decoders. That is defined in the DCC functionality. The decoder has no controler. The normal controler you have is the user interface hard and software. The instructions for the decoder are transported via a simple network over the power supply of your model railway. Any computer that can generate these instructions can make the model perform. The point is that you need some kind of hardware to satisfy the needs of the decoder. By using blue tooth there is no need for extra hardware. It would be interesting to see what happens when you have 26 loco's on the blue thooth connection. My headphone allows atleast 2 connections, but only services one. and then mixes up.

I think where they go from here will really define whether this is a good or bad venture (much like TT). If they make them reliable, add ability to customise sounds, improve compatibility with other manufacturers (I agree entirely reasonable that they prioritise their own locos initially), I think they will revolutionise DCC.

Bluetooth chipsets cannot ordinarily burn out; they are designed from the ground up to consume tiny amounts of power, of the order of a few milliwatts on average. This is why your phone can have Bluetooth permanently enabled. The part of a DCC decoder that *can* burn out is the motor controller, which may be dissipating a few watts in its failure mode.

Especially with some of my Diesels from the 1990s and earlier, including some of my Triang locos (Like the Class 35, where only one Bogie has pickups), where there's a lot of space inside the engine, it would be cool to get one of these DCC Bluetooth decoders specifically to get the power bank, as hiccups in the power are fairly common.

They come in several sizes including a remarkably small micro size. They're also quite reliable and are, IMHO, the gold standard of DCC Sound decoders. Definitely worth the investment, you should check them out sometime!

[@Cloudman572]

Interesting, is there a library of UK steam engine sounds that you can download into these without having to use dealerships/suppliers?

[@johndrew3202]

Thanks Sam. Very interesting video. Like electric cars, I think I shall wait a while until they get all the cons sorted out before I jump in with these. I guess it will be goodbye to any more TTS decoders soon to get these sold instead.

[@johnathanmichaeljackson6155]

P.S.: In America, the best DCC-SOUND Decoder is the ESU Loksound decoders.

[@SamsTrains]

Yes I've heard those are very popular! Thanks for watching, Sam :)

[@ianollman5006]

I believe that there is smaller version of the 21 Pin decoder for engines that have a speaker already fitted it is the R7402 HM7000-21: Bluetooth® & DCC Decoder (21-pin) whether you can still use the sounds not sure, the RRP is 44.99 pound, there is also a R7401 HM7000-N18: Bluetooth® & DCC Decoder (Next18-pin) at the same price. Hope this helps

[@Gooner-1971]

Sam - thanks so much for doing this. I have been wanting to upgrade my E1 loco to DCC & sound, and was just about to make a purchase of the next18 chip. Given that it’s way too big for that loco, you’ve saved me a lot of hassle. Thanks again 🙏

[@mikeking2539]

yes the size of almost any decoder is an issue, I use DCC and "Normal" DC for operating my railway, and just because a loco has a decoder socket inside, does not always mean that there is space for a decoder. I have tried to install two different types of decoder into one of my Hornby 08 shunters, one a direct plug in type but the body would not go back on fully. And the other was a wired version, but again trying to make it fit somewhere was the issue. We are 15 mins in to your review, and we have 3 locos that the new decoders don't fit into... And Big Kendo makes the same point as well!

[@davew2452]

A reasonable option / technology for those wanting an 'adequate' sound profile. For more realistic sounds and better functionality the ESU and Zimo decoders will do a better job, but this is coupled with the expertise of the sound experts who make the recordings and produce high fidelity sound and fuctionality to replicate as far as possible the 'driving' of a train. These guys need our continued support. One advantage though might be a price reduction in the hardware (decoder) costs. Accurascale for example do not have a massive difference between DCC ready and DCC sound cost, whereas buying a separate sound decoder and loaded profile is much more expensive.

[@wapphigh5250]

Agree 100%. Hopefully it will also put a rocket up chip makers like ESU and Zimo to upgrade their tech - eg how reprogramming CV's works and sound upload their chips. It also negates the use of programming tracks. Cleary "making these changes" straight to the chip via bluetooth using an app, is way way better than buying some expensive out of date box that only works on a 20 year old USB or serial port. Just MO .

[@sharkymcsharknose2979]

​@@wapphigh5250The standards for DCC were established by the National Model Railroad Association (NMRA, the North American model railway standards group) back around 1993. They are developing a replacement called Layout Command Control (LCC) that will hopefully be easier to program, amongst other improvements.

[@wapphigh5250]

@@sharkymcsharknose2979 1993?! Great! 30 yrs on.. it's about time!!!!

[@paulstubbs7678]

Nice system, although I hope they support it long into the future. The problem with a lot of smart devices, especially phones is that many people update their phones every 2 to 3 years, so you have to hope the app is still in the app store and that Hornby have not moved on. Unlike a PC where you can often keep a copy of the install files, you are at the mercy of that app store.

[@delaray7]

Does it really fit into the 08 shunter? They have it listed there, but I'd doubt it. Shameful that even Sam's Trains couldn't find a loco to fit it into. We have a fraction of your selection so we stand no chance. Hornby didn't test this? I prefer small locos on my layout as not every town had a Mallard streaking through it on a regular basis. Great show Sam, but I use my layout to relax, not rack my brains to simply operate one train in a simple oval. Good🍀Luck to those that enjoy this and miraculously retro fit all their locos with it.

[@jeffreysmith156]

I am an analogue runner and I cannot see me switching to DCC. This is just my preference and also because I have so many older locos. However, I found your video very informative. Hopefully, Hornby will expand the system with time. It is early days after all. It is a shame that one burnt out so quickly. I trust that you can try to get a replacement for free or a refund.

[@wapphigh5250]

You are missing a lot Jeffery without DCC- and for the life of me I can't see why these sort of developments by Hornby (making it easier and cheaper) can't change yr mind. Maybe watch there recent Q/A on HM7000 on there channel. It only aired a few hrs ago. Cheers. W

[@paullepine4765]

​@@wapphigh5250 I think you missed the point about having so many loco's? At £63 each loco X no of loco's= no hope or interest from many of us old timers!

[@muir8009]

​@@paullepine4765 I don't Dennis is missing much. I run dcc, dc analogue and ac analogue. They all have their good points, they all have their bad points, but I have found, and consistently have found, the analogue systems to be far and away the most reliable and easy to use, with an edge to ac analogue however that's used on more niche trains. I'm not getting rid of my dcc layout, but the additional layouts/ scales I've acquired since are all analogue

[@OlivierGabin]

@@muir8009 Like you, I have both, and I made choices depending on scale/ease of installation/type of traffic. UK OO and N -> DCC for me, as continental HO and N. Japanese and US N -> analog, zero DCC socket in Japanese engines, and use of painful to install DCC boards on US models. Plus you run US freight trains on long distances with minimal shunting, especially if you choose single track lines, which mitigates the need for DCC decoders. Japanese traffic is nearly all passengers EMU/DMU with no shunting, so minimal appeal for DCC. But that's my way to do things. Honestly, if I started from scratch today, I would certainly stick to a full DC solution for lots of personal reasons, first one is I am a scrooge.

[@earlfreeman93]

Sam as Jenny stayed in her video on the hornby bluetooth the app would run any of the other bluetooth decoders other than it own which means that if you have a loco equipped with a bluenami decoder you can't run it from the hornby app.

[@Demo-xu6bl]

For The Flying Scotsman when he tested for the power outage. It takes around 40 seconds for it to then continue on what it was doing before the power headed out

[@PaulBriden]

Mine blew up just like yours, exactly the same thing. I did not even get to digital control. I got 5 minutes of use. Sent it back to Hornby, they are replacing it.

[@CustomiZe_]

I originally thought that in true hornby fashion, they've only designed the chips to fit into hornby locos but after reading the description on the website, it states that it is suitable for 00,H0 and some smaller scale locos, so it looks like they are supposed to be universal. I guess you're supposed to check the dimensions before purchase but designing a 18 pin socket that doesn't fit into 18 pin locos I don't really understand.

[@CustomiZe_]

@@Haymarket47 no but most locos with an 18 pin socket have an average size of the ones that Sam tried and I would say you need the chip to fit around 75% of locos for it to be a universal chip.

[@SamsTrains]

They are supposed to be universal - Hornby claim that these conform to all relevant NMRA standards, which in this case is another lie from Hornby. The NMRA defines the length of a sound decoder as being 25mm, and these are significantly larger. This is why the decoder fit into *none* of the locos I tried!

[@Beatlefan67]

Does one not have to earth oneself when touching electronic kit these days? Back in the day on BT we always had to wear an earth strap to avoid 'wounding' or completely blowing up kit in exchanges and payphones.

[@Elkarlo77]

As an IT-Technician: The PCB is too long, most likely the End of the PCB is the a Lower Energy Bluetooth Antenna. A small Antenna Socket and a wire would be better as it would have shortened the PCB. Common use in Notebooks, but it would have costed more, then a PCB printed Antenna. As it would increase the compatibility to other Locos, i think the 0.2 cent more would be adviseable for Hornby's when you want to sell a System, increase compability, so that the Odd non Hornby's Loco can be intregrated. The long Update and Download times comes from the Bluetooth choosen, BLE uses less Power and but has a much lower Data-Transfer rate. BLE Drops from 24mbit/s to 1-3mbit/s in Base mode and to 128kbit/s, 500kbit/s, 1mbit/s, 2mbit/s in Low Energy mode depending on enviroment.. I think it runs in Lower Energy mode and Sam lost the speed lottery with one channel at 128kbit/s. Never forget that Bluetooth share the same frequenzy's as Wifi.
