Crikey Charlie, if you looked under some of my layouts in the past you’d be in intensive care! 😜 should say I am much more disciplined these days but I suppose when I was doing things on a budget...and in my case I knew myself where everything went 🤓 I just got given a digital set up by a friend who is “upgrading” so I can stop being a dinosaur, so this has helped to familiarise myself with things I realise I am going to need to know. Still a bit intimidating starting something totally new after 40-odd years of doing things another way, but hey 😂 That website for Railway Scenics looks like a godsend so thank our very much for the heads up on that one 🍻 And finally, thanks for taking the time to do make another interesting, informative and entertaining way to pass half an hour at the end of the week 👍🍀

I use .75 flex. - it's nice and cheap, and the runs are naturally easier to keep tidy. The soldering to the track took an age, but with wago connectors beneath, it made it really simple to connect, (and to alter after my tired and drunken evenings led to short-circuits!) Thankfully Railway Scenics is just down the road! 😀 I actually came here to find your bus-bar manufacturer/stockist, but it's not on this video... great work, and keep it up sir.

Everything explained and neat wiring does go a long way to help fault finding, than a spaghetti junction nightmare.

A useful video, I didn’t fully understand everything, being new to DCC however it does give me an idea. A will build a testbed first similar to that shown in ‘LAYOUT WIRING for DC and DCC and all gauges at Chadwick Model Railway’ This should help to start to understand the concepts better, for I move to the main layout. Thanks Charlie.

[@peetywondr3256]

Charlie, as always, you are the best at explaining things for us "newbies". I loved the de-coupling at 28:34, there is always some fun surprises when sorting things out for the first time. Just proves that we are human and there is always room for improvement . . . I loved the conversion talk about mm wire and their AWG equals. Being an ex electrician on the other side of the pond (USA), I fully understand the AWG info so your conversation about your side of the pond was very helpful when listening to you and others discuss wiring. Also, being fluent in telecommunications / data, I will be right at home with making data cables from scratch and I definitely understand color codes - your use of them to differentiate different circuits. I think I'll follow your lead here and use Blk/Rd for buss / dropper wiring Yel/Blu for auxiliary/point motor wiring and green for frogs - good choice. Also good to see you worked out the helix "slippage" issue - one loco and 8 couches is impressive. Stay healthy my friend. Keep up the GREAT! videos.

[@ChadwickModelRailway]

Great comment Pete, frogs are green hence the wire colour.

[@aniburns329]

As for wiring, I only have limited space and run on DC and don't really need to run a DCC layout as there is only myself and maybe a friend helping out . Model Trains are one of the most,if not the most expensive hobby this side of Uranus!! Sorry,bad gaff there. Anyway wiring up my layout is fairly straight forward. Not many points to power,some signals and building/street lights,no sound effects (only by me), and two transformers for each 'foreign' main line ,ie,up and down, and a jimmy box I built from Dick Smith electronics years ago for my only local line in the freight yard. This box is just a simple two way switch small unit with a heat sink and holder that plugs into my multi pole female socket via a two metre long cable. Had it 30 years and still going strong!! This channel is great for giving me lots of hints and tips and also information for maybe one day expanding my layout,as I have built it in standard sized interconnecting modules that have 'dead end' track, dual mains and single mainlines that end @100mm from edge of layout to allow space for 200mm connecting straight (I never connect modules on curves or crossovers), for future layout expansion when I have more time and space to do so , I've found this to be a practical approach. I learnt some of these skills from my time in a model railway club when I was a member from 12y/old to @ 16. Even though it was an N gauge club, I ran both at home (HO & N gauge). Big shout out to The Sydney N Gauge Model Railway Club (SNGMRC). Not sure if they are still around as I don't live in Sydney,nor Australia anymore! I do often come here to visit family and friends and stay a few months or so , but haven't had too much time for choo choo trains as I'm busy saving the world!!... Love your channel Charlie, keep it up and God Bless you all!! Take care. A big Cheerio from Csanad Bernath, somewhere on planet Earth!!

[@ChadwickModelRailway]

Thanks old Duffill, that’s very kind of you to say so.

[@avlisk]

Just a note that DCC Specialties also makes auto-reverser units which will change the polarity of a turnout's frog while simultaneously throwing the points. They are PSX-AR for slow motion machines like the Tortoise, andPSX-ARSC for machines that "snap" the points, as the Atlas ones do. I've used the PSX-ARSC for a decade now on return loops, and it's never failed me. You can use a Dual Frog Juicer to auto reverse a return loop too, but it won't automatically throw the points. (The Frog Juicers are fantastic devices, too!) Thanks for your videos.

[@ChadwickModelRailway]

[@AGregPalmer]

Charlie, the Digitrax command stations have a switch for O/G, N, HO. That switch affects the track voltage to line up with the NMRA electrical standard. 12V is what is wanted for N gauge and your switch appears to be in the centre position - N gauge.

[@ChadwickModelRailway]

Thanks Greg, but I did try it out in every position and the voltage never changed. So it could be a duff switch? Regards Charlie

[@AGregPalmer]

@@ChadwickModelRailway Hey Charlie- I just looked through the DB150 manual. It is rather poor with respect to power supply requirements. Usually to get 15V DCC you need1.4-2 volts drop for rectification and then 1.5V for the typical regulator used. So to get 15V DCC you would need 18.5V DC at least. Going higher just means more heating in the DB150. 15VAC would also work fine. I expect this stuff would be well covered in digitrax forums. Clues in Digitrax recommended supplies PS514 15VAC 6A, PS615 15VAC 6A. 6A gives headroom for current used by the 5A command station/booster. I would go looking for a 6A 15V supply for that.

[@evcolin]

[@PhillipCossar]

Hi Charlie, I just realized this video is two years old but something I noticed which I'm sure you already know is the scale switch on your DCS1oo is set to N scale so it will only give you 12 volts. When set to H0 you get 15 volts and when set to O/G you get 20 volts.

[@ChadwickModelRailway]

Yes, Philip, it was pointed out several times, but thanks anyway. Regards, Charlie

[@lilchris26]

Nice video Charlie even though your Digitrax stuff is not for me, I am on a NCE Powercab based system. I use the PSX circuit breakers they are brilliant, on my layout I have two for the fiddle yard up and down and two on the scenic section, the same up and down lines. You can adjust the trip current with jumpers, I have it low because I am on n gauge. You can also set the breaker to stay off on a short, I have a simple press to make switch to reset the breaker after sorting the fault. I also have led's attached to show the fault for the two breakers on the fiddle yard all good stuff. Keep the videos coming I always enjoying watching them.

[@ChadwickModelRailway]

Great comment mate thank you.Clearly the PSX breakers are working for you.

[@Mh-yo2sz]

Another great video! Just a quick note to make life easier, when twisting wires together, especially multiple doubles. Get your cordless drill out, use a clamp to hold the two wires firmly at the table, chuck the other ends firmly in the drill and twist until saticefied. The chuck will bugger up the wires a bit, but cut them off and unwind/straighten a few turns and off you go.

[@ChadwickModelRailway]

[@alecreid9983]

G'day Charlie, I really enjoy your videos, in regard to cable sizes for beginers who read these comments, the thicker the cable the less the resistance hence a lower voltage drop, ie use thicker cables for power supply cables to the track and smaller cables for control signal wires etc, hope this helps.

[@ChadwickModelRailway]

A good point Alex, something that we all take for granted that perhaps isn’t obvious. Regards Charlie

[@bobainsworth5057]

With the psx you can get terminal blocks on board and run wire to panel board with LEDS so when you get an overload ( I don't use shorts because everyone starts looking for a short not an overload such as 6 sound engines with current keepers all coming on at same time which will trip a 3amp rating) , or you can add a tone maker(?) to each board so it gives you an audible if you have an overload . See circle on psx board ? These are a great help telling you you have an overload ( you no longer get audible from main brain) and where it is. I love those volt meters but can't afford at this time. Great video good explanation of things. Thanks Charlie! Sorry to here you blew you power brain good luck with digitrax fixing. They said when they started supplying their new systems they would fix as parts lasted.

Another great video Charlie. Larry Puckett, from Model Railroader, has stated in one of his videos that you need a ground wire running between your command station and boosters and/or multiple boosters. You will notice in the middle of the Digitrax connector you have a ground port. I asked Larry about DCS50 through DCS52s, used as stationary throttles, (only on LocoNet) needing to be grounded to the booster. I happen to have an old 50. He didn't think that was necessary. If used as a command station with a booster then it probably needs to be grounded to the booster. Sorry to hear you smoked your equipment. Ouch! One of my suppliers has said that Digitrax is slow shipping product lately. That might be due to the restrictions in place for Covid. I use 14 AWG stranded wire for my buss and 22 AWG for my track feeders. I was using Posi-Taps but I have switched to Vampire Buss Connectors. Much easier when changes are required. Recently while working with decoders I had to buy a new set of wire strippers that handle 32 AWG. The speaker wires on Soundtraxx TSU-2200 Steam Decoders are that small. The other wires for track power, motor, LED headlight, etc are 30 AWG. So, 30 on one side of the decoder and 32 on the other side. I hope you get your trains running again soon.

The Western class 52 loco looks like a very good runner with low power consumption and hauling a realistic number of coaches up a gradient and curve resistance. With such a good headroom for amperage, my thoughts are coach lighting and feeding the power from the loco to the coaches via the AC voltage from the loco pickups and with tiny connections run a bus through the coaches and take a spur to feed the lights in each coach saving any more drag from coach pickups. Another thought is that in valve equipment such as audio amplifiers it's quite common to twist wires to avoid interference, especially on the 6.3-volt filament wires. One tip is to use a power drill and get your pair of wires and attach to a bench and put the other end into the chuck and slowly turn the wires to form a very good twist and uniform. Very good explanation of model railway wiring which has come a long way since my Hornby Dublo 3 rail set I had as a kid, yup I'm vintage and no exhibition at Ally Pally this year either!

Hi Charlie. Another informative and entertaining video. My end to end layout is purely dc. It is amazing how far things have advanced in the last few years.

[@ChadwickModelRailway]

Great information James, thank you. Regards Charlie

[@100SteveB]

I love the added technical aspect that DCC brings. Yes, i know that with ordinary DC you can achieve a lot, but it does not compare to what can be done with DCC. I love the way you lay everything out, and make it easier to understand how everything interacts. Now, seeing that Barnstaple is my local station, I was rather chuffed to see you were going to call your branch line station Barnstaple, but, after watching your white board presentation in this video, i see your branch line is going off to Barnstable, which I think is in Cape Cod in the USA! Most impressive indeed. 😉😉😁

Thanks Charlie, an excellent video as always. And this one in particular contained lots of helpful advice. I really do like those DCC Concepts Alpha Meters, I will be investing in some as I progress the construction of my railway which is likely to end up with four power districts, potentially six. Interestingly you and I have several things in common with the railways we’re building, including it seems, colour coding ! I’m also using red/black for track feeds, blue/yellow for the accessory buses and green frog wires (well, it makes sense really, seeing as frogs are green 🐸. Take care Charlie.

Mmm perhaps!

[@JamesPetts]

I approve of power management. One power management device that you did not mention, which I use, is the MERG DCO. One has to be a member of MERG and build it oneself, but it works nicely, is solid state, good value for money and can be switched down as low as 1.5A (or even 0.75A with a very simple modification).

[@ChadwickModelRailway]

Thanks James, hopefully some folks will try it from your post.

Hi Charlie, great video, I am still on analog totally, I do have the odd headache but it seems to run ok,I use mostly solid copper wire with some lighter droppers, I do like the idea of your system,one day maybe when the budget allows, stay safe and keep well, cheers

I look forward to your video`s Charlie, but this one was as clear as mud lol, Ive just got O gauge garden railway with radio control loco, so this went over my head, but so entertaining.

Sadly Les, I can’t please everyone and this video clearly wasn’t for you. Hayhoe perhaps the next one will. Regards Charlie

[@george_kennedy]

Hi Charlie, before you send the DCS100 back, you might want to check with a multimeter set to DC, the voltage between the ground terminal and rail A, then ground and rail B. The two should be around the same and around half the desired track voltage. I assume that you have checked the AC supply output is kicking out the right voltage. All the best, George.

[@ChadwickModelRailway]

Yes I have checked the input supply George, but I will certainly take your advice. Regards Charlie

Hello Charlie, I’m not into DCC but it’s good to know that if and when I do take the plunge these videos are there as a guide. That Western really charges up the helix now. The design change was definitely the right thing to do.

Since subscribing, I've gradually worked my way through all the videos and have to say the ones on all subjects DCC have been fascinating, including this one One thing I'd be interested in seeing is a prototypical HST with two power cars to see if they could be synchronised to work together

[@ChadwickModelRailway]

I’m no doubt that they can Martin, but adjusting the CVs to that accuracy may take some time. Regards, Charlie

[@davidmorris8847]

Another cracking video, Charlie - thank you! A suggestion - and an apology if you've already covered this somewhere - if you're a team building a layout then document both your wiring plan and wiring convention from the off, and insist everyone adheres to it. Hopefully then you'll avoid that member with a penchant for yellow wire going off-piste when they're working "un-supervised". Plus too you'll have a baseline to refer to when expanding or fault-finding the layout at a later date. P.S. good practice for personal layouts too 🤗

[@ChadwickModelRailway]

An interesting point David. And perhaps it would’ve saved the gentleman’s embarrassment when we eventually met up. Regards Charlie

[@SammoKarm]

Ive got over 60 sections on my layout so what I have done is bought 14 different colours of 0.2x 24 cable so that I can mix them and this lets me fault trace easier. If ever there is a problem. I never use the same 2 colours together more than once.

[@ChadwickModelRailway]

Stone the crows Sam, that’s a lot of cable. I chose a cheaper option with using printed identity sleeves. Regards Charlie

[@SammoKarm]

@@ChadwickModelRailwayI think you will agree, At the end of the day as long as we can easily fault find if needed, then that is the main criteria.

[@davidcurrie8429]

Hi Charlie, Another great video. I've just looked at the voltage output for the DCS240 in the manual (yes I do read them) It says on page 25. "The DCS240 can only OUTPUT approximately as much voltage as it is receiving. If you are only using a 15V DC power supply the DCS240 cannot output more than 15V DC. Use a power supply that approximates your planned track voltage." I would guess that you have a 12 volt DC power supply attached and your DCS240 is working fine. Regards, David.

[@ChadwickModelRailway]

The DCS 100 would still only output 12.3 V with a 15 V input. Regards Charlie

[@davidcurrie8429]

@@ChadwickModelRailway The manual for the DCS 100 advises to check the voltage unloaded, I'm sure you have read the manual. I presume you have checked your DC supply is good and not dropping under load. Regards, David.

[@kevinmartin1065]

Hi Charlie, great video as always, I am liking the education on DCC and associated equipment. It would have been interesting to see either a multimeter voltage reading on both the power outputs to see if there was a difference on the meter or if you swapped the alpha meters over just to check their calibration! Just a thought.

[@ChadwickModelRailway]

Valid points Kevin. I shall take a look, regards Charlie

[@grahamg6415]

Hi Charlie I always watch and look forward to your videos every two weeks and find them a great help and the way you present them holds complete attention up until the end of the video, even my wife who has no interest in model railways watches (some) of your videos and even says Hi Charlie; however, I was concerned when you said the largest wire size you used was 0.75mm2 (24/0.2), which is rated at 4.5A. If your command station / booster is set for 5A the wire is not protected under unforeseen fault conditions. IEEE state even for low voltage applications which includes model railways the minimum current rating of the wire should be 20 - 25% greater than the protection device. If the command station / booster cut-out is set for 5A the DCC bus minimum wire size should be 1.0mm2 (32/0.2) which is a 6A wire (see manufactures data sheets and the railwayscenics web site) i.e. 5A x 1.2 = 6A. This then provides full protection of the wire under UK regulations. When using DCOs the minimum wire size can be reduced between the DCO and track according to the DCO cut-out setting i.e. 3A cut-out use a minimum wire size 0.75mm2 (24/0.2) which is a 4.5A wire, 2A cut-out use a minimum wire size 0.5mm2 (16/0.2) which is a 3.0A wire etc. The solder connection to the track can be considered as chassis wiring and it is OK to use a short say 50 - 100mm smaller wire (I use 0.5mm2 (16/0.2) for track connections), that connects to a larger dropper wire this ensures any heat generated from the wire can be dissipated through the track and the adjoining larger wire. In reality it is unlikely that in a model railway’s normal operation any problems would be experienced using 24/0.2 and 16/0.2 wires, but an unforeseen fault that causes an excessive current draw could result in the wires running (very) hot if the wire is rated less than the protection device. Hope this is useful for you when wiring your extension boards.

What an outstanding comment Graham, extremely useful thank you. Regards Charlie

[@briansmith9946]

And I went 'DCC' because I was told, "You only need two wires!" Something you didn't specifically mention that I'm sure you do; Keep your points/accessories on their own Power District. BtW: I always make a pot of tea before sitting down to watch you.

[@ChadwickModelRailway]

Hi Brian, yes my points etc are separately powered. Regards Charlie.

Roco tried that... and had to increase to 19 volt output to have working magnetic points.

[@Llamberg.Railway]

Charlie I feel your pain on connecting AC to the dcs240, this is one reason I am now using PS2012 power supplies as I was concerned about mixing different types of power supplies. One point you didn’t cover on the PM42 and PSX was that the PSX can deal with inrush current and can determine if it’s a true short circuit or just an initial start up surge especially with sound decoders and lighted coaches, the PM42 can not determine this and just shuts down. Can’t agree more about the Alpha meter great kit I have 9 of them, I have found it more accurate than the ramp meter.
