I mention in this video that trains can get stuck on Electro-frog points that are set against their direction of travel. This causes a short so the train cannot move. By creating a separate “track power bus” for point operation, this situation will not arise. However, the wiring does become more involved.

[@AmauryJacquot]

wiring all the accessories on a separate booster is a good idea anyways, as it will allow more power to the locos from the main control station

[@peterbudd1803]

Yes I agree. Currently my accessories are on the same power. However I have a new power booster which I will implement in the new year as I have seen the accessory issue with points before. @@AmauryJacquot

[@antonyjerome7478]

A dcc accessory bus does not involve particularly more involved wiring. It is simply another power district in effect.

[@steveksi]

That is what I was thinking. I guess Digitrax has separately protected channels?

[@ericv435]

if you put SMAILS is the power that you get out you're digital control centre enough if you only use SMAILS or a different like a module that use normal 12v like u showed is better for bigger layouts

[@charlesgwyn2115]

Love the SMAILS. Digitrax stationary decoders tend to "go up in smoke" after a couple of years, so I've replaced most of my Tortoises and Digi decoders with SMAILS as the failures have happened. The decoders in the SMAILS have been very reliable so far, with less wiring required.

[@ChadwickModelRailway]

Thanks Charles, for an excellent recommendation. Regards, Charlie

[@MRBenchwork]

This is probably one of the best explanations of a model railroad product I’ve seen. You did a great job of simplifying things in an easy to understand format.

[@ChadwickModelRailway]

That’s very kind of you to say so Mr Benchwork. Regards, Charlie

[@bryan_lane]

Thanks Charlie, interesting and food for thought ! Like Simon Bradshaw, I also use a separate Accessory Bus so wouldn’t have the issue you describe around stranded trains at short circuited point frogs. Currently I am using DCC Concepts iP Digital point motors which, in the main, I like. They’re very similar in concept to the SMAIL. But I have had problems with the iP Digital motors in that out of 24 I purchased, so far I’ve had to send 8 back as they’ve failed (in fairness though none have failed in the last six months although another one is starting to make the telltale sounds of failure recently). But, and this is an important “but”, DCC Concepts offer a lifetime warranty on their motors so sending them back isn’t an issue beyond the aggravation involved in getting under the board to remove and replace them and the cost of postage. I’ve recently installed two MTB MP1 point motors with a YaMoRC controller and I have to say that I’m pretty impressed with them. So I’ve been sitting on the fence as it were about whether to continue with cobalt iP Digital or MTB for the rest of my railway which is a significant further requirement for point motors. Reliability is crucial to me. Having recently seen a video showcasing new digital versions of the MTB motors in the form of their forthcoming DP1, DP4 and DP10 products, I’m starting to lean over the fence in favour of MTB ! Either way, as good as those SMAIL motors appear to be, I don’t think they’re for me.

[@ChadwickModelRailway]

Thanks Bryan, for such an excellent comment. However, I have Issues with the DCC concepts lifetime warranty. Perhaps it’s not the lifetime of the component, but rather the lifetime of the company! Regards, Charlie

[@stefaanhessens6970]

Is this video on KZbin regarding the New Digital Mtb switches ?

[@ChadwickModelRailway]

No, the main production run has to appear at the retailers. They are known as the DP4 and DP10. Once available, I’ll film a review. Regards Charlie.

[@alanmusicman3385]

When I first discovered (of course via one of your videos) the DCC Concepts equivalent of SMAIL I was really happy because (ever since I returned to the hobby in the 2010s) I always had the feeling that the idea of controlling point motors via intermediate driver boards (DS64 et al in your Digitrax context) was a very 20th century solution. In these days of the WiFi controlled light switch (and all that example represents!) attaching accessories direct to "the network" (in this instance DCC) seemed like a much neater and modern solution - even noting the side issues you highlighted here. Of course there is still a need to solve one major issue in most commercial products and that is how you simplify and ruggedise the feedback path. For example, your DCC controller may command a motor to set a point, but there is no out of the box mechanism for the motor controller to acknowledge completion via the same communication path - you need to create your own back channel (I am using WiFi for that). So, it's not ideal, imagine if your computer needed two broadband cables one to send commands to access website and another for the actual website content to travel down! So, DCC doesn't help a lot with command/Acknowledge at the moment, though you can use RailCom as a back channel, but sadly not all devices support that. Thanks for a nice walkthrough these useful products Charlie.

[@ChadwickModelRailway]

Thanks Alan, for an interesting comment. With my system LocoNet provides that data flow to and from the modules. Regards, Charlie

Excellent video Charlie. Seeing this reminded me that I've followed your wiring standards since I returned to building my own layout and do not regret it for one moment. Another plus is that if I loose my way or run into a problem I have your tutorials readily available to set me right. I can't thank you enough.

[@ChadwickModelRailway]

Thanks Steve, that’s very kind of you to say so mate. Good luck with your project, regards, Charlie

[@steamfan007]

Another timely video, Charlie. An excellent no-nonsense demo of the differences between the basic Tortoise and the Smail. I also appreciate the comments from Simon and Bryan which underline the need for a separate accessory bus; I was starting to lean in that direction but their remarks have convinced me. Also, interesting reference to the MTB MP1 with which I am totally unfamiliar so maybe it's time for a follow-up Swift on that subject? Cheers, Peter

[@ChadwickModelRailway]

To be perfectly honest, Peter, I would keep your powder dry until MTB announce their new Digital point Motors. Regards, Charlie

[@bryan_lane]

@@ChadwickModelRailway Yes agreed Charlie, interesting times ahead in the point motor department I think.

[@andrewclarke7707]

I think a Swift on the MP5/6 would be useful tho. Especially regarding their profile and how they fit into smaller spaces? Just a thought.

[@GDGRailway47712]

There was a full video on the MP1 and MP5 a while ago. I note there is also now an MP6 and MP10 available although I've not read up on how they are different from the MP5 (looks like the MP6 works from a short burst to make it compatible with passing contact switches so people can replace solenoids). I bought a few MP1 motors to play with and was wondering if they would work with an Arcomora DCC Next decoder. I do like the MTB MPx motors as they don't consume any current after they reach the end of their travel.

[@KimKeyboardKimFokken]

I did all that stuff, with smail directly from my digitrax DCS52. I programmed each of my smails from the DCS52. He is using a DT602T which I have but that handheld is connected to the DCS52. Each one of my switch motors has a switch signal signals (Green and Red).

[@ChadwickModelRailway]

That’s great news, Kim, I’m so pleased you’ve had such success. Regards, Charlie

[@Vonzack]

I use a similar TT300 point motors and to get around the issue where the DCC Bus has shorted, we operate with power districts. So we split the bus with a Digitrax PM42, one district dedicated to Accessories, the others to the running lines. So in the case where you run into a closed turnout and the bus shorts, it only affects that district and as the TT300 is being run from another one, you can still switch it without issue. For wiring, the TT300 is powered from the Accessory district and the Frog it switches is powered from the appropriate running line district

[@ChadwickModelRailway]

Thanks Vonzack, what an excellent solution. Regards, Charlie

[@davidcurtis5398]

What I like about the Tortoise is that even though it is slow, you can make it even slower by using resistors in the line. Then you can make them as slow as you want. The one thing I didn't like about the Tortoise was that you used a dpdt switch. I like the single buttons better as then you can place them in the track plan on the side of the road. It seems that we are in opposite schools about the kind of control. I guess that this comes from the fact that I was raised on the old coil switch machines and started with the buttons in the lines on the front of the road. On my last club layout we went as far as to have red and green LED lights inserted in the track lines on the front of the road. When you set the switch the green lights would come on for the track that the switch was set for and red lights would come on for the branch that the switch was thrown against. It was very easy for the operator to see just where the rain was going and for visitors to operate the road. I really didn't realize that these had a 9 year warranty!!!

[@ChadwickModelRailway]

Thanks David, for sharing your thoughts on the tortoise. It remains an excellent commodity. Regards, Charlie

[@bryanthesnail5383]

Hi Charlie, as said below another excellent and informative video. I used a different policy on this subject which gets rid of the shorting issue and any possible derailment issues, I fitted auto-frog devices to the live frog and then used the point machine switch to isolate a section of track leading up to the point so that is the point is against the loco it stops short of the point.

[@ChadwickModelRailway]

Thanks Brian, you’re not the 1st to mention this alternative arrangement. I shall certainly look into it. Regards, Charlie

[@roystudds1944]

Very interesting video Charlie, as are the comments. Thanks for the effort you go to in making these videos and explaining everything so clearly. An amazing insight to how complicated a hobby this can be if you choose to go down that path. Roy.

[@ChadwickModelRailway]

Thanks Roy, I’m so pleased that you find the channel interesting. Regards Charlie

[@Bliz0516]

Great video Charlie. As others have commented, I also use an additional booster for all my accessory decoders. I found that the stall motors, can trigger current detection block sensors depending on the number of turnouts. I use cobalt digital IP, and have been very satisfied.

[@ChadwickModelRailway]

Thanks mate, that’s very interesting. I think smails are aimed at a smaller layout. Regards, Charlie

[@gerbenligthart3611]

Hi Charlie Nice piece of equipment. I have solved the dcc problem by connecting all the dcc point switching decoders to a separate booster which does nor switch off due to short. I know it takes more wiring but on a layout which is devided into several booster sections anyway this is not a big issue. It does savesyou from manually pushing locos arround

[@ChadwickModelRailway]

Thanks Gerben, however, it is always disappointing that we have to find a workaround to solve the designers omissions . Regards, Charlie

[@stevemcgeachy6953]

Great explanation on the good and bad of Smails. I am building an HO layout with DC power. I bought Tortoise switches for my layout. But think given your explanation here I think I will stick with the Tortoise even if I eventually switch over to DC. Thanks for all of the great videos.

Another useful video on product Charlie, thanks for taking the time to do all this. Frankly I dont know how you do it; hvg just become an oldie as the Aussies used to say, planning the day is key as so much to do! (I DIY all my classic car maintenance while fitting in MR construction, kit building and gen house stuff). I watch your videos to keep my mojo going as not alot has moved in 4 years and my last status was fitting analog Cobalts with their central ADSFX 8 way decoder boards, all with independant power from a 16v feed from the HM2000 that came with the Orient Express set. I then use an ESU 50200 which I invested in and has been the best thing since sliced bread IMO esp the loco and acc selection and track planning LCD layout screen. I really need to make a concerted push to get the track wiring completed and run some locos as watching your video makes me v jealous. 😉

[@ChadwickModelRailway]

Rest assured, Paul , time management is a gift and a curse. Regards, Charlie

[@stevejubb1915]

Hi Charlie, as others have said the issue of shorts shutting down what is essentially your ‘control bus’ is an issue that needs to be considered. If you’re implementing PM42s (or other power managers) you could dedicate one of the sub-districts as an accessory bus or feed the accessories from the command station output directly. As another option I’ve just picked up a couple of the Tam Valley Depot DCC Boosters which are aimed at solving this problem as well as providing a universal 5 A booster (the functionality is selectable via an on-board link). Really enjoy your videos and these discussions, thank you - rooting for you to get the 100k!

[@ChadwickModelRailway]

Thanks Steve, I think we all know the answer, but the publicity behind this switch machine is somewhat one-sided. Regards, Charlie

[@csxrensville5105]

Good video Charlie. I've used Tortoise motors for many a year. There is another way to operate them via DCC. I use an NCE Switch 8 Mk2. It controls up to 8 motors either via the Throttle or panel switches. Combined with a Hex frog juicer it's all a very easy system to set up. Plus with the Frog juicer you can run against the frog and not short out the whole layout. It does mean the loco derails, but thats what happens in real life! 😃

[@ChadwickModelRailway]

Many thanks for your interesting comment, and your alternative method. Still somewhat unsure about the derailing! Regards, Charlie

[@EsotericArctos]

I have some DCC enabled point motors. I usually run the point motors on their own power district so they don't stop working if a short or power outage occurs with track power. I did initially have them powered by track power directly, and I did run into that issue of shorts causing issues, so havign a separate power district for the points helped reduce the hand of God coming into the mix.

[@ChadwickModelRailway]

Thanks EA, you have worked the same solution as many other modellers. Regards Charlie

[@donstratton6343]

Thank you, Charlie. Very useful, well explained, discussed at the right level and tempo. And thank you for not droning. You have confirmed for me my decision regarding power. Two buses as stated by commentators below. I have started with Cobalt iP Digital but I'll give MTB a look. The subject of your next swiftie video, perhaps? Oh, and I'm a toggle switch guy as well.

[@ChadwickModelRailway]

[@anthonystevens8683]

Another top video Charlie, it's great to hear about the pro's and con's of this kit. Electrical shorts, even in hot weather are something to be avoided. Certainly if the 'hand of God' is busy sorting out something else at the time. Once again, many thanks for sharing.

[@ChadwickModelRailway]

Thanks Anthony, I’m so pleased that you found it interesting. Regards Charlie

[@paulhowes8756]

Hi Charlie - These shorts are a good way of dealing with specific items. 🙂 I think you are missing a trick here with the smail! I am considering these at £22 from Hattons because I have installed mostly Traintronics TT300 point motors on my Train Controller layout and they are now as rare as hens teeth... The TT300 also has an integrated DCC decoder) I don't suffer from your short issues because I have a second DCC bus around my layout for accessories from which I run the point motors - this is run from a booster like your districts. The track can trip and still leave power on the points so I can move the points. This does require the use of a handset as TC does not let you move the point when track is frozen. I will buy some to test however the only drawback for me is the depth below the board compared with the TT300. One test I would like to see is that do they retain their position when power is removed or do they default to a position? The TT300 did default and after investigation I found I had to change a CV to turn off the auto DC power function for it to retain the last position. Edit: I now see that a few more of your disciples have a second bus for accessories. Edit 2: I now have 3 so will swap out one shortly and report back.

[@ChadwickModelRailway]

Thanks for your comment Paul. However, it’s disappointing that people need to modify their wiring systems to accommodate a short fall in the design. Regards, Charlie

[@philipbancroft]

If you can solder electronic parts (not surface mount) I can recommend MERG. I use CBUS, and the kits that can operate points and Train On Track Indicators (TOTIs) are very much cheaper than ready made items.

[@ChadwickModelRailway]

Thanks Philip, I do hope the subscribers find your suggestion useful. Regards, Charlie

[@lgrfbs]

The problem you raised at 13:00 is solved by having a separate booster for the switching decoders. Thanks for a nice video.

I agree, but it kind of defeats the object for what they were designed for, namely simplicity. Regards, Charlie

[@lgrfbs]

@@ChadwickModelRailway Unfortunately it is possible to create the same breakdown with ordinary turnout decoders, how do I know this? have fallen into that trap myself on a large club model railroad layout.

[@tommilton5753]

To prevent a short circuit by a loco running into the frog when the points are set for the other road, isolate the rail leading away from the frog, about 12 inches, say. Then connect a wire from that rail to the common terminal on a spare switch on the switch motor. Connect the track wire for that rail to one of the other two terminals (trial and error to find the correct one). Then that length of track will be unpowered when frog is incorrect polarity and loco will stop without short circuit.

I have all my points on a separate accessory bus. This is when I have a short I can still operate my points. My power districts I have 8 using Psxx breakers. They report shorts back to TC via on opto detection module. I can then “ deal” with the short via TC. I also have an emergency stop. That has 2 functions either a dead stop for all trains or a slow stop where each train will run into the next block and stock. These functions are controlled by physical buttons on the facia or via tc switch board. Each button only emergency stop controls/stops it’s respect power district

Charlie makes a very good point below Michael. As I noted in my comment, I’ve installed both Cobalt iP Digital and MTB point motors. I find the MTB motors very versatile and look forward to trying out the new digital versions.

[@michaelimpey1407]

@@bryan_lane thanks, but there is also the cost, and I have already laid out for the IP Digital motor.

[@bryan_lane]

@@michaelimpey1407 Yes indeed, I’ve already bought 24 so I’ve got the same issue as you. However, going forward I’ll have a need for quite a few more motors in my planned build and I’m almost certainly going to switch allegiance.

[@matthewneleigh567]

My experience on my club layout leads me to think that a switch problem that requires direct manual intervention to clear is a bad idea in general, and unacceptable on a large model railway... as such I think I'd avoid those SMAIL switch motors unless there was a very good reason to install them in a particular location, and ban their use with track power on the main line, entirely.

I understand your point of view Matthew. However, I believe they are aimed at the smaller layout Moadeller. Regards, Charlie

Very interesting and informative video as usual Charlie. I'm sorry to say that this just adds to my dislike of DCC and all that goes with it. My H&M solenoid motors of 60+ years still work fine, they've cost very little in comparison and the simple addition of a microswitch or two operated by the arm on said solenoid is perfection itself. The only thing not in their favour is the sudden action of the solenoid and the fear of this possibly breaking the point. Well; sensibly fitted and adjusted there is no reason why this should be. I've certainly not experienced it. Doubtless, we could/will continue this conversation at our next meeting (see you there!) Remember I have a Grandson and I'm not afraid to employ him on my side! Happy Christmas!

[@adrianolsen-woodhamwoodtur4980]

Perfect timing Charlie! I’m now at the stage when I’ll soon need to pin my colours to the mast on what point control I’m going to use. My prospective layout design (at least the current one 😳) has 27 points on it, so I’ll soon need to decide exactly how I’m going to control them all. This new Smail option has now given me yet another possibility; although I’m not sure if that’s a good thing !! Although my locos are all run on DCC, I was leaning towards analogue control for my points, with a nice pretty control panel (or several) but maybe now I’ll think again. There are just too many decisions to make 😩

[@ChadwickModelRailway]

My advice, Adrian, is to keep your powder dry until MTB announced their new Digital point Motors. Regards, Charlie

[@chugwaterjack4458]

Interesting, especially the multi-source controls. On my layout, with thirty some points in the main yard, I get all fuddled when trying to remember which number point to throw as the express is nearing the junction. All my points are powered off a separate power bus, and the Cobalt and MBT motors have little or no draw after moving. To this end, I have moved to Megapoints controls with the driver boards located close to the points, with the single cable from the master panel to the driver boards. I have a mix of Cobalt analogue IP's and MBT MP10's, both of which have SPDT switches integrated, so when the express nears a junction, I Iook at the control panel and push the button for the junction depicted thereon, which throws the point and also changes the indicator light on the board, without using any of the onboard switches. At the junction, one set of onboard switches operates the signal, while a second activates the 25 cm (+/-) approaching from the "backside" along with the frog. If the point is against the loco, the approach is unpowered, so the loco never gets to the unpowered frog, so the hand of God (and the associated 2 meter arm) never gets called on. Throwing the point sends power to the "dead zone" and to the frog, and we continue on our merry way. I have also made a handheld controller based near the second switchyard to control those points. (NOTE: as a British modeller in the U.S., one of the challenges has been learning the lingo. Your videos go a long ways towards figuring out most of the differences; guards vs. conductors, drivers vs. engineers, platelayers vs. MOW trackmen, shunters vs. switch engines, etc.)

[@steved5356]

I guess all points should be protected by a signal and by using block detection you can use auto braking until the points are changed correctly, then that short will never happen. Basically the signal controls the movement of the points, and releases the loco to proceed only if points are set correctly. Obviously that requires more electronics, e.g. abc capable decoder in loco, point position sensor, block detection and signal tech capable of triggering points, and maybe route tech to switch everything correctly.

[@ChadwickModelRailway]

I see that you’re getting a hang of this DCC stuff Steve! Regards, Charlie

[@jamescraft672]

What I did was to control the SMAILs from a dedicated DCC circuit rather than using track power. That eliminates the issue with locos running into shorts and having to use the Hand of God.

[@ChadwickModelRailway]

Yes James, that seems to be the only way around it. However, it does mean yet another DCC run. Regards, Charlie

[@ngaugefouroaksstreetstatio6932]

Hi Charlie, very good review, potentially one of the sets of 3 terminals could be used to switch power to prevent a loco driving through a point set against it. This would require making a cut one one rail in both tracks that lead to the point, track power is then fed to that isolated rail via the point motor meaning the loco can only proceed when the point is set correctly. It could possibly be wired in to the frog power terminals. Thoughts? all the best

[@ChadwickModelRailway]

Wow, that suggestion has attacked my grey cells indeed. I shall have to think about that one. Regards, Charlie

[@ngaugefouroaksstreetstatio6932]

@@ChadwickModelRailway think of it as a mini isolated section just prior to the point, the loco would stop if the point was set against it unless it had stay alive.

Regarding the problem of a short circuit that you describe. I am not a railway modeller so please excuse my ignorance. The problem is caused by the fact that the SMAIL is powered from track power and that will have been turned off because of the short circuit. Why does the SMAIL have to be powered by track power in the first place ?

Hi Bob, it was designed feature to minimise wiring. Regards, Charlie

[@Bob_Burton]

@@ChadwickModelRailway As I say, I am not a railway modeller, but is there anything stopping you powering the SMAIL from an external supply ? You would need to connect the ground (negative) side of the track power to the ground (negative) side of the external supply to provide a common signal level but that is common practice in the world of electronics, which is where my interest comes in.
