I can envision a control system that has low voltage AC through the rails that is only used to charge a hi tech battery pack in each locomotive.
Each locomotive would have a chip that receives a control signal wirelessly from a palm sized throttle with voice commands for functions and addresses.
Consists are linked to each other for speed matching, lights, horn and bell from the lead unit only no matter which direction.
I'd arrange for the wireless decoders to be "DCC compatible" because any fancy UI or IxD you code would be very easily ported to use with DCC track modulation...
wrench567 Having the same make of decoders would be grand. I have such a mix from old Soundtraxx, QSI, Loksound from version 3.5 to the latest 5, BLI Paragon and Blueline, TCS WOW, and Tsunami 2. When I set up the decoders I function map sounds to a standard for Deisels and a standard for steam. It makes it easier for running them. Pete.

Agreed on the convienience of a standardized decoder - my experience is similar to yours in terms of the variety of old and new decoders on the layout. I even have an old LC series decoder in a shay.
Most of my installs are sound and usually hardwired. It generally takes some time to complete the install. As a rule, I don't replace decoders unless they fail. This leaves me with a variety of different decoders running on the layout. As mentioned in the post above, I also use function mapping to create some continuity across brands and generations of decoders.

see stuff at: the Willoughby Line Site
There is something to be said about sticking to one brand...IF...the brand doesn't also decide to re-engineer and reconfigure their decoders. I currently use the new Tsunami, factory installed, the first issue released in 2006, several stalwart QSIs, and LokSounds of at least three different versions. The QSI's and the Tsunamis are the same in every respect except the reset, but the LokSounds are quite different, and sometimes I have to figure out which function does what when I run a LokSound for the first time in a year or two.

There is no question that some percentage of DC (DCC ready) locos are bought by "fussy" DCC guys who install what they want. I'm guessing 5% to 10%. It has become a RTR hobby, especially regarding locos, for a lot of people.
To answer Doug's question, Bowser locos are now DCC w/sound or DCC ready, no other options.
But also don't discount DC users who buy/have bought DCC locos and removed the decoders. Of my current 145 loco fleet, easily 30 locos came with DCC, or DCC/sound, which I removed and rewired. Reason? The price was right or they only came that way.
Bachmann for one sold locos with non sound decoders for years and included an 8 pin jumper for DC users to remove the decoders.
I have seven BROADWAY locos, they no longer have decoders, and most now have Bachmann tenders.

PRR8259that approximately 55% of the new locos sold are dcc, with 45% or so plain dc.
I don't have a dog in this hunt, but purchases might not reflect how they are bieng used. Are the 45% dcc ready, whereby a buyer might then plug in a decoder.
Just sayin, most companies sell dcc/sound and dcc ready. So 55% would have sound, and the 45% might eventually have straight dcc, leaving actual dc lower.
I don't know how Bowser segments their product line as far as sound equipped, decoder equipped, dcc ready, or no dcc plug at all.

PRR8259 My friends at Bowser have shared with me that approximately 55% of the new locos sold are dcc, with 45% or so plain dc. That was during 2021, and applicable to the pre-orders and sales at that time. They acknowledged that each run sees a slight increase in dcc orders. As for me, I use both. I control which power is going to the track through a DPDT (center off) toggle switch. I have brand new Athearn Genesis diesels that are plain dc and run just great pretty much right out of the box, and I have some of the very same model that have full dcc/sound/etc. and also run well. I actually prefer the plain dc units for their running characteristics at this time, even after adjusting the acceleration and deceleration on the dcc units to smooth them out. I have no plans to convert over the last MTH plain dc unit on hand or the newest Genesis plain dc units to dcc at this time. I plan to continue to use both modes of power for the forseeable future.

Interestingly, those percentages are very much in line with every random survey we have conducted on this forum over the years. And just like Bowser is reporting, further change is slow.
These numbers also suggest that interest in sound is similar percentage wise, or at least not a high priority for many people.
ATLANTIC CENTRALHow large is a large layout? Dr Wayne only has a simgle power feeder. But he does not have seperate blocks in the traditional sense.
I'd consider my layout to be a medium-size, and yes, there's just one pair of wires powering all of the layout's track.I do have blocks, but their purpose is simply to allow a train to be parked, while another train on an adjacent track can pass, either in the same or oposite direction of the parked train.There's normally only one train running at any one time, but it may have multiple locomotives, depending on how many cars are beng pulled, and especially if the train is on an ascending grade. Even if the locos cannot be programmed like a decoder-equipped one, I've found that multiple locos, even only somewhat similar in size and power, will co-operate quite well if the train is heavy enough to actually require that number of locos.
The main lines on my layout are single track between towns, but with double track where they pass through the towns...that's where the so-called blocks are located.
When some of my grandkids were quite young, I used to let them run a diesel locomotive (not pulling a train), then added another loco when they weren't looking, and continued doing so until there were a dozen-or-so in motion (some had caught-up and coupled to other ones), then as they circumnavigated the layout, I began plucking them off one-at-time, until there was only one left....end of the game.Even with that many locos in motion, I never noticed much of a difference in speeds as locos were added or removed.Nowadays, with most of my diesels either gone or simply in a display cabinet, it's usually only me running a train with maybe only one steamer, but if I get well into it, it could be multiple locos, front, middle, and rear and maybe 50 cars (or more).
DoughlessDr Wayne might chime in. I believe that he powers that large DC layout with only 2 wires, but solders every rail connection.
You're certanly right about the two wires, and most of the rail connections being soldered, but my layout has five fairly large bridges, all of which are removable, mostly for periodic cleaning of the fake water beneath the bridges.Those rail joints do have joiners, but they're not soldered in place, and I've had only very minor glitches in the many years the layout has been in place. Usually sliding the joiner back and forth a bit, or giving it a squeeze with pliers will fix any interruptions.
I'd venture that when I shuffle-off to the last roundhouse, nobody will want any of my locomotives, due to the fact that there's likely no room in them (loco & tender) for a decoder of any type.I sorta think that my freight and passenger cars would meet the same fate, too, simply because I've modelled an era (late '30s) in which few modellers likely have any interest.

DCC does not inherently put any restrictions on where a train runs. It is much like "see and avoid" VFR flight rules. A set of rules has to be implemented to prevent crashes - like you said. DCC is inherently very effective at givng the experience of the train crew operating independently out on the railroad. An overlay of some kind - rules or signal system - has to be added to DCC to restore dispatcher control.
A DC block system is much more like IFR in the aviation world - a ground controller (dispatcher) gives you clearance to operate in a particular block of air space. Other aircraft are not permitted in the same airspace block at the same time. A DC block control system is well-suited to emulating dispatcher control of the layout. The DC block system is not nearly as well suited to mulitple train crews each doing their own thing - unless there is a lot of track between them.
I use DCC for our modular setups, but still use DC at home where I'm operating on my own. I have too much to do to convert my locomotives to DCC. Because true modular layouts are different every setup, DCC makes a lot more sense than DC, even though operating rules are needed to keep the layout functional.
Everybody should use the control system that best suits their operating needs/desires, and not worry about others.

maxman PM Railfan (like we need to run a train from a cell phone! gees thats lazy but we have it.) Well, not to involve myself in someone else's strong opinion, you fail to point out that a smart phone allows one to run trains on the railroads of others without needing to purchase a dedicated throttle for the other person's railroad. The folks around here have installed dedicated routers which they have interfaced with their railroads that allow this to happen. All the smart phone owner (and I'm not one of them) needs to do is download the appropriate app to their phone. And the bare bones version of that app is currently free, with the full version around $10. Much more cost effective than needing to purchase the dedicated item.

The day that a smart phone, or other touch screen device, is the only way to run a model train, would be the day I would get out of the hobby.
My new layout will support 10 operators, I have 10 throttles.
I agree and understand that most new people go DCC, even if they still start out with a simple DC setup.
I also understand that there are several factors that drive this, not just youth or technology.
I think I covered much of this earlier.
Trends, modeling approaches and philosophies change over time, and cycle around again.
Right now, "being the engineer", small layouts, simple methods of operation, are popular trends. That combined with sound is a natural fit for DCC without busting the budget.
Large layouts are a different story.
Yet large individual layouts do persist. Not everyone buys into "less is more".
And again, it is unlikely that any new technology will completely displace DCC or DC.

First, i dont think anyone is keeping stats on the use of DC vs DCC. I expect its pretty even nowadays. That is until alot of us old hoggers (who only had DC when amassing our fleets) head for that great enginehouse in the sky. Then DCC will take over almost completely. I expect manufacturers will drop out of the DC only game. Only DC left will be us hold outs, and those with old equipment (still running i will add). AI should take the fun out of it for sure.
As for running your trains while looking out the model's cab window via micro-cam, well..... that exists today already. One pair of Oculus (the original, not the one Disgracebook owns now [all after the originial Oculus]), a lil bit of programming, and your on your way.
We already have multiple train control systems (like we need to run a train from a cell phone! gees thats lazy but we have it.), we already have micro cams and videos galore of people running their layouts. So instead of piping the video to a monitor to watch, pipe it to your Oculus. Oculus #1 is plug-inable to things like the electronic sewer (internet) or your local wifi.
I cant imagine this taking a rocket scientist to pull off. Just one good Model Railroader (as usual)! Most expensive thing here will be your DCC loco, those are astronomical in price and mostly unattainable. A pair of Oculus, new, went for $600 (remember - go for Oculus #1) if you cant still get the #1. The programming should be done free.... its just typing and in todays world, any millenial can do this.
With Oculus 1, DCC loco, mini cam, your prolly looking at $2000. With DC loco you can drop that down to prolly $800. Sounds like a good project for you - Good luck!

PS: Id leave companys like Micro-whatever and CrApple out of this. If they get involved, youll need an account to play with your trains, 3 tap verification, and i wouldnt be at all suprised if a fee wasnt imposed, and certainly "ADs" all of the place because people still think you need ads to do ANYTHING! Not to mention the scam email youll have to sift through to get to your waycards, employee schedules, etc.. Think of all the malware youd have to clean out of your trains if you used a 'Chrome' controller. You think your track and wheels are gunked now - HEH!
DCC vs DC vs twisted or utp
Boy you guys really get going on stuff. 1st, cables. Over the years I found out that you ALWAYS twist and bundle cables. A cable all by itself and not working will grab anything it can get to so it can tangle. It is like sex to a cable. You know the scenerio - have cables in a bag or box? Bet you can't just pull ONE out! I have even gone so far to put individual Cat5 cables or a couple of them into their own baggie. You do not need a bunch of twists per inch for this, just enough to keep things together. One of the fall-out of this is that twisting *could* help with your leading edge ringing in the DCC case. Doesn't do anything for overshoot if present. Now you possilbly have bundles of cable that are controlled. If you need to change something you *usually* can pull one set of cables from the mix with no sex involved. Or, it might be easier just to mark both ends 'spare' and run a new twisted pair or pairs to where you need it. Also, with Cat5 cables - riser cable is NOT twisted per-say - if you peel back the plastic you can see that the cable pairs are somewhat twisted and are solid. Patch cables are different, these might or might not be twisted at a specific twist per inch and are stranded. Riser cable is the easier to deal with as it is a more solid of cable and you can 'punch down' to terminate it where you choose. I still am amazed that the new DCC devices do not have punch down blocks as it would make stuff way more easy.
DC is just that - plus and minus ( ground ) current and in one direction. Simple Ohms law governs this as to voltage drop per length of cable; assuming you have everything soldered proper and tight.
DCC is different as there is a frequency component to it. DCC is still for the most part a plus and minus, but has rise and fall times that must be met ( slew rate ). As far as I am concerned, best way to keep DCC cables working at their best is to solder your rail joiners for each block ( if you are using detection ) and provide multiple paths from the big DCC bus to the rail; not necessarily at those joiners. If you use 14ga for the big DCC bus, there is no reason you can not use smaller and shorter wire for those feeds - some say 28ga, some say 18ga. I suspect that what ever you use you should stick with it ( and same color code ) for ease of figuring out what is wrong when it goes sideways.
1st thing I do when DCC goes sideways is to hang a scope on the big DCC line and see if my signal is doing what it is supposed to be doing. If so, start splitting stuff up and see where is doesn't work. If not, what happened: did you add yet another DCC device? Did a DCC device die? What?
In the case of DCC the manufactures are continously adding new widgets to put on the DCC bus. Guess what, each time you insert something, that bus gains in capacitance ( impedance ) which will slightly slow those rise and fall times a bit. If you have a small(er) layout you may not notice. Medium and bigger you *may* see stuff not working immediately as it used to, and/or is intermittent. Sooner or later you will get to the point where it will not work at all and then you would need to split the bus with yet another power district. Splitting the bus is not guesswork, although giving it your best guess as to where to split it could help. Keep in mind that you could be wrong.

Douglas,
Our rail has a higher resistance per foot than wire becuase the metal used for rail is not a good conductor - it is plenty big enough in cross section.
I understand, I have many hours of opps sessions on DCC layouts.
I also understand that I don't like onboard sound, I don't want to install 140 decoders, my era and operational scheme does not require controling headlights or speed matching largely dissimilar locos, and CTC and signaling are not made easier or less wiring intense by DCC.
I understand very well the few features I give up, and I understand well the features I gain.
I'm a "big picture" guy, and I like running trains both in and opps session or just in "display mode".
I like vast scenery, modeling more than just the 80' either side of the tracks, I like long trains.
In case you have not been following, here is the track plan for my new layout. Room prep underway, first area of bench work soon.
I've been at this hobby since 1967, I watched the whole developement of command control, I seriously considerd DCC - twice.
Again, my layout will have:
Wireless radio throttles
Detection, signals and CTC
Simple one button route control of turnouts which will be controlled at the dispatchers panel and at local towers. This allows full operation with and without a dispatcher on duty.
With a dispatcher on duty, a mainline engineer will have an experiance pretty much like DCC - but with less buttons to push......
Even without a dispatcher, walk around control is provided by local towers by simply setting the route thru the next interlocking (one button) and selecting the next block (one button).
System maps will display the location of all active mainline trains to operators.
ATC will stop any train that runs a red signal.
And it does not even take a computer to do all this.
Industrial areas and yards are largely route controlled and turnouts will be manually controlled in those areas for the most part. Occasionally some cab assignments require a button or two in those areas.
The layout will supppot 10 operators and make use of a dispatcher (or two) and a yardmaster.
Or, for dispaly purposes, allow operation of 5 deticated non conflicting routes, while still allowing switching of the yard and primary industrial areas.
The layout will stage about 30 trains ranging from 35 to 50 average 1950's freight cars, or passneger trains as long as 15 cars.
wrench567 Doughless richhotrain Rich. Short answer. No. Voltage drop is the same. Thanks, Pete. So, why would a DC user settle for a single pair of feeders on a large layout? Wouldn't voltage drop adversely affect performance? Rich Rich, on my 50 linear feet of track, the voltage drop was significant for the last 10 feet...when the rail joiners were unsoldered. (I like to get the train up and running ASAP, and the effect of the voltage drop was to decelerate the train as it approached the town, and accelerate the train as it departed, built in momentum so to speak, so I was in no real hurry to solder the rails). Once I soldered the rails, the voltage drop went a way. Dr Wayne might chime in. I believe that he powers that large DC layout with only 2 wires, but solders every rail connection. I can't expaling the physics, but I assume fully soldered nickel silver code 83 rail functions just like a buss wire, albeit I think the thickness of the rail might cause more reisistance than a properly gauged buss...unless I have that backwards. Your unsoldered rail joiners was acting as resistors instead of conducters. Restricting the flow of electricity. Electricians hate the water hose analogy when discussing electrical faults. So here goes. Take two garden hoses and join them together loosely and without a washer/gasket. Turn on the water. You get some water out the end of the hose but the joint is leaking a good portion of the water is being wasted because of the leak. Put your thumb over the end and look at the leaking joint. Good connections are very important to good electrical flow. Code 83 rail probably has the same conductivity as 18 gauge copper wire. A continuous run of 600 feet of nickel silver rail should have nearly zero voltage drop and handle 1 amp of current without issues. Pete.

And when you say that code 83 rail offers about the same conductivity as 18g copper wire, is there a concept that says a piece of rail can be too large of a diameter that impedes current flow over a linear distance? (but that our model train tracks probably never approach that diameter).

Rich
Rich,
One of the fundamental problems with these discussions is that unlike you with zero DC experiance, many of the people who are critical of DC only have bad experiance with DC having never operated on a well designed DC system.
They tried on their own early on to build a layout, and wired it from the Atlas wiring book, and found it hard to operate.
There are good and bad approaches to DC, and what suits one persons goals may be totally useless to the next person.
I have known more than one modeler like Wayne, who just run one train at a time and the whole layout is one circuit with some kill switches to isolate parked locos.
And I have operated on systems more complex than my own.
One simple way to start to understand more advanced DC systems - they are less about being the engineer and more about being the dispatcher. By one means or another you progressively give the train, or trains, "authority" to proceed into the next block - much like real trains - which do not just drive around willy nilly like DCC lets you do........
