Why are we still using DCC?

[@TheTrainFreak]

As a Network Admin by trade, IP is just an internet protocol or a connection to a device. That is no difference than the connection with Bluetooth and the CV values within a DCC decoder that stores the address. DCC also runs on AC, not DC which allows the pulsating signals to work. IP communications also uses pulsating electrical signals through copper or a pulsating light through fiber. Wireless is a different animal all together as you have different variations between Radio Waves, Bluetooth, IR, etc... A lot of people use DCC accessories which add even more devices and can jam the pulsating signals on the bus which is why I have went the LCC route (seperate system) to control my layout accessories. DCC for trains and LCC for layout. Thing with DCC is, that once a signals is sent from the command station, it's not sent one time but several times over and over until the next command comes in from the system. Imagine how many commands are being sent every millisecond when you have several operators or several things going on the layout at one time. - Jason

[@gravesclay]

Several corrections to your post: DCC is not AC. It is differential PWM DC. IP communications uses differential signaling on copper with pwm speeds approaching microwave, and amplitude / phase modulation on fiber / coax. Bluetooth uses radio waves why differentiate? The modulation scheme and bandwidths vary from 802.11 but they do share the 2.4GHz ISM band. DCC accessories aren't going to jam the bus. DCC bus is broadcast based (one way) return information is done via current sensing. The whole system is non-blocking, however as address space and command intensity increase it can take longer to transmit the full message simply because the message gets longer. There is only ever 1 command station on DCC layouts, additional controllers talk to the command station utilizing a side channel (like loconet) to communicate. I think you are mish-mashing the side-channel, and the actual DCC signal.

[@TheTrainFreak]

@@gravesclay I guess my original source misled me on the AC vs DC but after reading your post and doing a little research, per DCC Wiki, the DCC signal or bus doesn't use PWM on DC but the decoder supplies PWM to the motor if you really want to get technical. As for the extreme technicals on how TCP/IP, Wireless Interfaces work: I didn't want to get too technical on that as the average person in our hobby, one wouldn't understand or two wouldn't care, however, you are correct as to how it all works in the fine little details. The reason to differentiate on wireless is that it depends on which bands are being used but then again the average person doesn't know that a Bluetooth band won't work with a WiFi band even though it could cause interfere with each other and that's simply to not confuse those who haven't went to school in our field. To keep it simple for the most people out there, copper is signaled with electrical currents and fiber is signaled with pulsating lights. As far as the DCC system, there is an input bus (the cabs or throttles) and an output bus (track) which does broadcast. The commands aren't sent just one time but repeated and if you have a lot of devices, let's say 50+, then you can start to experience delays in controlling your locomotives. I used to do signalling, block detection, turnout control all with my NCE ProCab system but with the locomotive control delays, a very good friend of mine (Dick Bronson, RR-Cirkits) suggested I go to LCC (Layout Command Control) which uses a CAN Bus that does two way communications and pull all the accessories off my DCC system. Now I no longer have the delays or jam signaled of the locomotives responding. With that being said, all I can do is share my experiences as to what did and didn't work for me. Have a great day!

[@cmdr_ultraviol3nt]

@@TheTrainFreak I’m pursuing Network+ and I was just as surprised as you were to learn this. It’s a common misconception, but it’s one of those distinctions that’s not really necessary to know unless you’re trying to make something close to the signaling itself, or something closer to that part of the, uh.. OSI model? Does that apply here? Whatever a model railroad’s equivalent of the OSI model is

[@michaelhaueter6011]

Another Network Admin here. Another big consideration for IP vs DCC, is that you can get a lot of devices that are DCC enabled, such as signals, detectors, switches, turntables, etc, ect. If these were all wireless, on a layout even with 30-40 of these DCC items, you might start running into wireless communication issues over wifi, wired would be fine more than likely, but ethernet is probably overkill as a solution for this kind of setup.

[@RoamingAdhocrat]

​@@michaelhaueter6011It's possible to use a CAN bus to operate accessories, rather than wifi or DCC. The UK's Model Railway Electronics Group maintain a range of CAN modules for railway layout builders.

There is no need for capacitors or stay alive units.

[@MichaelDoornbos]

As someone very tech oriented and new to being "back" into trains after a hiatus from my 80s childhood, I've been wondering why DCC is still dominant as well. I've been implementing DCC on an RP2040 just to learn the protocol on a deep level. It IS simple to understand and seems fairly robust, so it has that going for it.

Not sure if you’ve heard of this but there’s an open source project called DCC-EX that implements the DCC booster on Arduino Mega, I’ve played with it for a bit and it’s great

You talked about using ballast on hopper cars: 50yrs ago I had some '20ft' hoppers on my N scale and I used modeling clay for ballast. It can be shaped to look like any load. I pressed a little track ballast into the surface to make it look like coal or gravel. Haven't had any stability problems with the cars since.

[@johnhermanson5249]

When I got into train control, my first system was Marklin, which back then cost an arm and a leg and WAS the original DCC protocol. Decoders had a 50% failure rate and Marklin wouldn't warranty them unless install by a "authorized" installer (which allowed them to hide the failure rate). Then came DCC ( I bought the Lenz system in '93, the creator of DCC) and Marklin changed their protocol to Motorola so it wouldn't be compatible with DCC. Brown rubber cement like Pliobond or Walthers "Goo" are excellent glues. Personally, I never use hot glue.

[@Rob1_5]

I'm about to start building an n scale layout and I've ordered a ScaleTrains Operator N scale CSX GEVo and I've been watching your videos trying to learn as much as possible before building my layout. I've decided to model mid 2000s to 2010s Norfolk Southern loosely based on my home town and industries around it.

[@mr.e1944]

I started into the model train hobby a couple of years ago. I was going to buy the NCE Procab after looking at the available options. However at the store the sale guy could barely get the train to run. It kept going over unclean track and dying out. I went to a friend house who had a full layout. Same thing. It got me wondering why we were using a 1980’s technology. I was going to make my own remote control train. However I discovered Ring Engineerings Railpro. It is wireless and a cheaper alternative. Since I did not need a track signal I decided to go dead rail and installed 3.7 LiPo batteries. Now I can make my track layout plan really prototypical. No juicing frogs or reverse loop switches. No bus lines, just lay track and ballast and have fun!

[@mpetersen6]

This or something similar should be way forward. I can understand some of the potential issues people can have. Fear of battery fires. Limited battery life in terms of running time. Charging. Does the locomotive have a charging port or can it be parked on a spur and charge off of the rails. Or perhaps wirelessly. Another potential issue l can see is compatiblity between DC, DCC and onboard power units. At least in terms of visiting other layouts and bringing along your own equipment. Although for demonstration purposes that would work fine. Going this route does not eliminate the need for power under the bench work. Switch machines for turnouts and power for visual effects come to mind. Granted turnouts can be controlled with under table mechanical linkages. Using an R/C control cable between the operating handle on the facia and the turnout operating lever comes to mind. Effects such as lighting, powered car dumpers etc. well that's going to need power. But that should be a lot simpler to supply. Right now N scale should be about the limit for on board power IMO. I would assume that you could do Z scale. Especially in passenger equipment where you could install the power supply and receiver in a separate chassis. Onboard power in a freight locomotive? I would not say it can't be done. For all l know someone is experimenting with it right now. What does it take for this to go mainstream? The first step is a standard in terms of control system. An app you can run on a cell phone would be ideal. What frequency would be used? I'm no electronics wizard so don't ask me. Then it takes a manufacturer willing to offer the system as ready to run equipment. I have seen some pretty small R/C drones and l know there are R/C cars and trucks in HO.

[@MacTrom1]

Thanks. And I hope to have some “work in progress” photos this year. My athern big boy runs on a 11” minimum radius just fine. Don’t think I’ll try anything less. lol

[@JeffDM]

While DCC still leaves things to be desired, I'm in agreement with others that TCP/IP on everything on the layout adds unnecessary cost and complexity. You would only need a bridge device to connect it to the internet, leave the layout to be all DCC. I don't know what sort of physical layer you would need to signal TCP/ IP over track but the whole thing seems like a solution looking for a problem.

[@Crosshair84]

As someone who doesn't do model trains, but works with computers, TCP/IP strikes me as trying to open a can of baked beans with an axe. Yes it will work, but it is going to get very messy very quickly and not actually work any better than the old solutions. You're just going to trade certain problems for different problems.

[@chrisjones4423]

Great video Jimmy. We only upgraded to DCC from DC less than a year ago. We were looking for the next big thing, but I think what is holding the model train community back from the next big thing are the locomotive manufacturers. There is no reason that a locomotive can't come ready to run from the factory from a phone app or computer program with nothing more than a track power source.

[@MilwaukeeF40C]

Phone apps HELL NO!

[@TwoRailfans]

@@MilwaukeeF40C well not on a phone, but something the side of an iPad. We usually run our setup through an app on my son's iPad and it is easier to control multiple trains and controls at the same time than the controller that came with our DCC system.

[@immrmessy]

The main reason DCC is still around is that anything new doesn't solve anything. You still need a constant power connection.

[@neiloflongbeck5705]

A fairly easy way to add extra weight is Deluxe Materials Liquid Gravity. It's a granular non-toxic dense material which only needs a glue to hold it in place (I used Roket Card glue on my N gauge wagon kits). Simply pour it into the void where you want to put some extra weight (keeping it clear on anything that turns or moves) and then glue it in place.

[@StefsEngineering]

I wouldn't like the models to have IP functionality. Not that I am oppose it in general but I can see a future where all models always need to stay online and you need subscriptions to run your trains. "want to do some shunting? buy the shunting package for 20dollars a month and experience the awesomeness!"

[@StefsEngineering]

I am specifically talking about the IoT aspect, not the protocol in general. (see for example the pinned comment)

[@dda40x]

Yeah, exactly! On a related note, if I control all my locomotives via an app, that's great, until the app stops working because the manufacturer went out of business, or doesn't care anymore about stuff they did twenty years ago. Maybe that will never happen, who knows. But DCC is an open standard, well established and all. There will always be DCC command stations available to buy, or ways to build one yourself.

Has anyone ever had their Internet go down? I certainly have. No Internet means no trains? No thanks!

Discussion for the next q&a: What do you do when you get in a rut and can't find any inspiration for your own layout? I just completed a section and I want to do a double oval that connects to it and I just can't find inspiration. To the point that I barely touch the layout and prefer to go work on my friend's layout.

[@ajkleipass]

What's the difference, if any, between your friend's layout's design and yours? Similarly, what model railroad articles and videos draw your attention the most? From my own experience, space and financial limitations have always left me with layout envy for layouts not as constrained as mine, and, consequently, left me disheartened with mine and ignoring / avoiding it for months on end. This is the old "the grass is always greener..." thing, in that we are so focused on what others have that we don't that we blind to the pitfalls that other layout owner faces. Yeah, he might have a 20-track staging yard capable of housing 70-car trains, but we don't see him having to climb a ladder and crawl under his enclosed porch to reach it, fighting through cobwebs of brown recluse or black widow spiders all the way. 😮 Thankfully, cable TV hasn't started airing "Model Railroading Sent Me To The ER" episodes yet. 😂

[@lellopesce]

Take a deep breath, close your eyes, and then, remove all you have done so far. The reason is, it is not working. It is better to design something in front of an empty room, then try to add an "undesigned" section to an already existing section, especially when there is no motivation (you call it inspiration - no motivation, no inspiration).

[@DK-nv9zu]

Nothing wrong with taking a break from hobbies. I'm either in the garage working on my old car or building my model railroad. But it's not uncommon for me to five or six months off from one or the other. I come back totally recharged.

[@kevo05s]

There are a few differences: I'm in N scale, he's on HO scale, I was done with benchwork and most of the track work, he had just started. He had a 4x8 double loop, I had (at the time of commenting) an 8'x7' U shape. Single track loop with operations all around. It wasn't so much "grass is greener on the other side" since I had more and higher quality, but it was overwhelming and it wasn't how I liked it so I wouldn't look at it. It actually took me until this week to remove two thirds of my layout and start fresh in those sections. Having a clean slate or a blank canvas really helps me create and get into it. I have now reduced in size to a 7'x7' L shape (2' and 3' wide) and somehow, having a smaller layout makes me happier and much less overwhelmed.

For Surroundtraxx you don't actually have to replace your decoders with digitrax unless you want the sound to follow the train in different zones on the layout.

why DCC instead of IP: the main issue is that the transmission line (the rails) are very sub-optimal, and IP would be way too much information per packet to have a good signal to noise ratio.

Nothing was wrong with the printer other than it was no longer supported, so the call to the mother ship did not work and now the printer will not work. Everything is wanting you to be connected to the internet and lots of them now are wanting to pay a monthly fee for the privilege to use a product that you paid for. One day you find your lights in your house not turning on and or off do to the fact you upset Amazon with a post on the internet. This did happen.

Why are we still using DCC? Because a lot of modelers have a ton of money invested in their DCC systems, DCC locomotives & accessories. I certainly don't want to switch to another technology. Although I'm not opposed to adding new technology like LCC. LCC brings many other options to the table, such as one touch routing. I'd love to see more videos on LCC.

[@thetrainroom]

It's very simple why we are stuck with DCC: Backwards compatibility and open standard. As long as new system isn't somehow backwards compatible, it's going to stay as niche application, as power modelers with hundreds of locomotives, won't have the means to convert all locos at once. Unless it's a standard backed by NMRA and MOROP, nothing is going to change, because manufacturer don't want to back a competitors system, which could change at any time, or might have licensing fees. I have started to spec a system which is IP based and would run on ESP32. The rules I set is that only existing standard and protocols are allowed to be used. The decoder could still understand DCC, but the new system would unlock all function. If you know how tiny the CPU in smartophone is, you could easily build that in H0 locomotive.

I originally bought Marklin Digital back in '89, 90. Not sure of the exact date. It cost me over $1000 back then and my wife almost killed me. :). It didn't have a walk-around throttle, just a base station. Decoders then were $90 ea. and Marklin would not warranty them unless installed by an "authorized" installer. This was, I think, a way to hide the fact that the decoders had a 50% DUD rate. Well, DCC was introduced and surprise, the Marklin protocol was the SAME as DCC. Soon thereafter, Marklin changed their protocol and a DCC equipped loco would not be compatible with it. I switched to Lenz DCC in 1993 and have always loved it.

[@DIYDigitalRailroad]

That’s amazing!

[@trainliker100]

The primary reason for not using some advanced protocol is that it is too ponderous (more bits to get the same job done). That's not the only reason, but probably the main one. For example, there are 14 fields in just the header. One of the HUGE advantages of DCC is that it runs at a startlingly low frequency in the world of digital electronics. The 1's and 0's have different cycle widths, but the average frequency will always be below 10 kHz. This is actually an audio frequency - it is that low. And this, plus using the FULL magnitude of the voltage swing (that is also used for power) creates an exceptional "signa to noise" ratio. This low frequency and large voltage swing is what makes it possible to run all sorts of bare bus and feeder wires (and remember, the rails are also bare wires) many feet all over a layout and have it work.

In HO scale, what is the best way to install a KD coupler in the pilot of an AHM/IHC Srteam locomotive (4-8-4) (4-6-2) ?

[@UFO4X]

Great video! I am laying down extruded foam insulation board for my sub roadbed. Some people wait until they lay the track to paint it. I wanted to completely paint it with flat latex paint, before I lay down any track. Would the paint cause issues with the cork roadbed sticking properly or even staying glued down? Just curious.

[@neiloflongbeck5705]

If you are modelling the UK railways Dapol has produced a few dummy locomotives and multiple units. They are the only company to produce dummy locomotives in the UK. One way to get dummy locomotives where no one produces them is to buy non-runner and strip out the motors.

[@allenbarnes7202]

I still use DC, I have 3 f-9 locos that are 40 years old

[@MosriteCharlie]

I have 2 MRRC Tech 2 12 volt power supplies that have, all of a sudden, reduced power. Is tths a sign of rheostat failure? These packs are decades old and I only run 12 V DC.

JImmy, really love your channel. I recently purchased a Soundtraxx 885022 Tsunami 2 TSU-2200 Digital Sound Decoder : EMD-2 Diesel for my HO scale 2-8-0 Union Pacific locomotive. Not sure of the brand since I bought it second hand My question is what speakers would you recommend for this sound decoder? Second question is I'm trying to control 16 turnout servos from a sensor shield instead of a PCA9685 on an Arduino Mega in JMRI through my Arduino DCC-EX and while I have added the turnouts to the Turnout table in JMRI I can't get the servos to move. Could you point me in a direction that might help me get this resolved or should I just switch to a PCA9685 to control my servos? Thank you.

[@BlamesmokeBuffaloNy]

Do you have merch for sale like t shirts?

[@MrTomStover]

I’m looking to drink coffee with other modelers. I can’t help but feel there are people that share my interest in model railroading in my own town. How do we find each other?

[@carlossantiago0234]

Hey buddy I have a question for you , I currently use NCE Powercab and NCE Switchkats for my turnouts however I’m building a bigger layout so I’m wondering if you know what can I use for my turnouts that’s simple to use and less expensive than the switchkats ? Thanks

[@hughanderson7698]

Hi!! Just was curious if you have looked into the blunami decoder from soundtraxx? I am thinking about using this to update some of my old DC locos & my DC layout. Just wanted so input on it , if it’s a good idea?

[@russrockino-rr0864]

It takes 20 to 30 years to get most MRR's to get on board with new tech, Jimmy. A good share of MRR's Resist Technology, IMO

[@eurovnik]

Why DCC? Because it's interoperable and good enough. A shame the manufacturers have been so short-sighted about an interoperable sensor and accessory bus. Thank goodness there's DCC-EX developing a more powerful open source system based on dirt cheap off-the-shelf hardware. May the manufacturers and their proprietary walled gardens fail.

[@menendezgilbert]

Dead rail would be nice if they can make a locomotive that will work just as well as with DCC

[@JanusLoggie]

I'm not even at DC yet!

[@doc8579]

I’m so old I’m still using DC. DCC engines are just too expensive. It’s nice but it’s no longer a hobbie when engines are $250-$500 each.

[@davidsprague6385]

Can you use an "N" scale decoder in an "HO" scale locomotive? For instance I'd like to start a small Traction layout, using Ho scale trollys. But because they have narrow bodies, I believe the smaller units could work. Thanks for any information. Best regards. Dave.

[@johnbusby5614]

Yes, you can use N or Z scale decoders in HO locos. Just make sure they are rated at least 1 amp for the motor though. Most of them are. I have used Digitrax DZ123 and DZ126 decoders extensively in HO locos as they are both rated at 1A.

[@wunzagain]

What are some solid smooth-running N scale small steamers? Looking at 0-4-0 or similar engines to kitbash into HOn30. Thanks!

[@AlwaysCensored-xp1be]

Do a search for "Narrow Garage" Japanese company making N gauge mechs.

[@RichsModelingTrains]

What are you using the hot glue for.

[@sbboice]

Hey Jimmy. As someone who is just getting in to the hobby (haven't built a layout yet) I had some questions about consisting trains. I've watched your and others' videos about DCC speed matching, but one thing I still don't understand is how you can control 2+ locomotives simultaneously. Do you have to assign them all to the same address to do this, or are there ways to bind multiple units to one throttle without changing addresses? Thanks for the great and helpful videos!

[@danp2779]

When locomotives get "consisted", they get a special "consist address" that handles that "one address controls everything" logic.

[@jimmeyscool]

Hi I was wondering do you weigh your locos?

[@fredashay]

Love your channel but I disagree on the DCC thing. DCC has been around for a while. It's proven. It's versatile. It's reliable. I hate the idea that just because something has been around for a while that it's time to throw it out and switch over to something else. I don't want to sell thousands of buckazoids worth of locomotives at a huge loss and go out and buy all new locomotives using your New Thing. And I don't want to set up a kludgy mix of DCC and whatever New Thing you want in order to run my custom and rare collectible trains (Rapido APT-E, Shinkanssen, NYC Subway trains, etc.) that won't ever be released again and can't be converted to your New Thing. If you want FPV or a camera car, that can be done easily using the same technology that drones and RC aircraft use... The only improvement I would like to see is Keep Alive circuits becoming standard on all locomotives and passenger cars with lighting.

[@dalecollier2853]

Hey Jimmy. I am working on modeling a modern layout and would like to know, do modern railroads still use 40 and 48 ft well cars? All I have been seeing are 53 ft cars. Drinking Amazon Solimo coffee.

[@angeloraimonde4660]

Best coffee made is called Da Bomb. Available at Menards

[@Scraghunter]

Robotics tech here. To me, DCC may not be new, but it's not maxed out yet. There's still a lot of growth left in the tech and speed in communication is one of them. And keep the compatibility between MFGs! That's a huge deal.

[@Phoenixknight79]

I am starting to collect all the HO scale locomotives that I'm wanting for my R.R. But at this time I don't have the room for a layout, does it hurt the units not being used and just sitting around?

[@markanthonyfrench5139]

Eventually the lubricants dry out and need to be cleaned out and replaced. Consider running everything once a year, even if it is on the bench, and evaluate the lubricants.

[@Phoenixknight79]

@@markanthonyfrench5139 how can I run the units if I don't have a layout or any way to set up a test track even.. my wife and i live in a one bedroom apartment.

[@gravesclay]

re: hot glue Use a high temperature glue / gun, not the low temperature stuff. It glues way better.

[@thecanadianredneckfarmer]

On your model railway do you scratch build any of your buildings? Also I am a 15 year old who has been model railroading scince I was 11 and I want to make KZbin videos but I have no idea how to get started, any ideas?

[@tonykane8866]

I have just gone all dcc and I have 4 locomotives that I have had dcc chips put In and all of them have been a pain in the a$$ , to deal with . One kato ph40 has been the worst ,

[@doctorno3912]

Friend had a similar experience when getting into the hobby with dcc. As much as like the sound and other features i opted to play it safe and start on dc myself. It's reminders like yours where I don't regret my decision.

[@bdlii]

Thanks for sharing. I have a bunch of older blue box athearn and some Katos and have been hesitant to ruin them. Nobody talks about the pitfalls.

[@JoshuaEhlen]

If the budget is there, I would buy one or a few higher end locos that already come fully DCC equipped. Just so you have some reliable (hopefully) locos you can run while tinkering with those manual installs. I would hate for anyone to lose interest in the hobby!

[@cbirailroad]

as a newbie to model railroading just 3 short years ago, I jumped into DCC with both feet, not knowing the depth of the pond. But no regrets. I am a retired CPA and definitely NOT an engineer, but I have found more than adequate support via print media, KZbin, and my local hobby shop and MR clubs. I have learned to ask a LOT of questions, many for multiple iterations, but I have also gone up quite a few blind alleys and made lots of screwups (like buying DC locos when I thought I was buying DCC). But that is what learning is all about. I like to watch trains run so not huge on prototyping or operations, and there is nothing more relaxing than having 3-4 running on the layout at the same time, with sound. One piece of advice to @tonykane8866, contact Ryan at Iron Planet Hobbies and explain your experience. I have found him to be a true helpful and patient spokesman for our hobby and all things electronic, and he has pointed me in the right direction and saved me grief on more than one occasion. And he won't try to sell you something you do not need. I'm sure Jimmy would agree. Also, BLI, Kato and even Atlas all market DCC ready locomotives, which can take a number of plug-and-play DCC or DCC/sound decoders. If you have a local train store or MR club, contact them. They are usually more than willing to help. Good luck.

[@cbirailroad]

Tony, don't despair of DCC just yet. I'm new at this too, not a techie by any stretch, but was able to upgrade my Kato F40PH Amtrak diesel by installing the DN163K0D decoder. It was plug and play and took about 10 minutes. No sound, but it runs great on my layout.

[@ChicagoCrossingRR]

Next think you know I'd have to have two-factor authentication on my 'net-enabled locos to avoid them getting hacked and (!!!) potentially run at non-prototypical speeds.
