Rob’s battery powered trains

“Hello Al,

As I mentioned in my last posting, I have been killing time waiting for my locomotives to be modified to run on battery. They finally arrived and I have been having a great time running them around my layout. For those of you who have not built your layouts yet, I recommend that you look into this method of running. There is no wiring to be done, you never have to clean your tracks and you can ignore all polarity problems with reverse loops and turntables and such since the track is not powered.

I run On30 with DCC and sound and have an NCE system installed. The installation involved isolating the motor from the wheels, adding a Radio Control Receiver and battery control circuit into each locomotive and supplying a battery pack. The system has a transmitter that I plugged into my NCE track output connectors so that I can use my existing system to run my trains. The system will function just fine with or without DCC. If you want to go the DCC route, all you really need is the decoders installed into your locomotives and a Radio Controlled hand set to complement the battery controlled system. For DC the same applies except you don’t need the decoders obviously.

I installed the the transmitter inside the roof of my depot and have included pictures of the components to give you an idea of what they look like. The yellow looking thing is the battery pack. It’s about 1/2 the size of my thumb and powers my locomotives without any problems. I have run with the bell and whistle on and found no hesitation in operation with these little battery packs. I don’t know how long they will run without requiring a charge as they are still going strong. The system runs on OO/HO and up but maybe could go down to N scale as well.

I elected to have one system placed into a separate car so that I could attach it to other locomotives without major modifications. All I would need to do is add a plug from the tender into the trailing car.
I forgot to mention that the system comes with an Off/On switch as well. I hope this gives some of the more adventurous of you some ideas for the future.


Thanks again to Bob – a fine idea: no wiring and no track cleaning!

Don’t forget the latest ‘ebay cheat sheet’ – it’s here.

Please keep ’em coming, folks.

  1. No why did n’t I think of that? Brilliant. If anyone can find a way to get this working with old N gge I’d love to know. I have used an old 12v battery to power a circuit outside and I’ve also used one of those 9v & 12v plug-in battery chargers/power units instead of a transformer & controller for a small exhibition
    layout that just round at one speed. Thanks for this int. D/

  2. wow amazing layout and amazing idea, best wishes on your upcoming layouts. if you could send me some emails for lans of layouts and anything to do with 00 gauge that would be FANTASTIC!!!

    best regards Jacob

  3. Good idea

  4. thank you. New adventure in deed! Can you saw more about the conversion routs?


  5. Very cool.

  6. For those of Us with various amounts of electrical,
    and electronic experience.

    Where can We order, and approximate cost of parts?

    Thanks !!! Duwayne

  7. Nice layout. Doing N scale would probably have to use a unit of rolling stock to have a place to put the batteries. To bad that we don’t live in an age where nano technology an it is just a trip to the local Radio Shack to get the materials to build a hybrid engine that keeps the batteries charged when it is running around the layout. Oh well what a nice daydream to have….

  8. Sounds like the ideal format for a garden railway especially in the UK.

  9. Okay, for your ‘N’ scale idea, here is an answer:

    The simplest way would be to take a boxcar or passanger car and wire up a set of rechargeable ‘AAA’ power cells in series, (equal to the required volatge of your engine), with a micro S.P.D.T. slide switch and secure the power pack to the inside bottom of the car. Then wire that up to a set of polarized micro sized plug and socket set that is connected to your engine by running thin stranded wires along the bottom edge of the cars. Of course, the power car would need to be nearest to the engine in the train consist. The power car then can be recharged using the same connector and matching socket mated to a proper power charger. If you create two cars the same way and connect them in parallel, When one is discharged, throw the switch ‘off’ on that car and throw the switch ‘on’ of the other car, and away you go.

  10. What is the cost involved to fix locos and other items?

  11. Great idea. It is an energy saving idea as well. Too many power packs run up the old electric bill pretty fast. I’d like to have a better idea of how long the batteries last.

  12. Bob, you did a great job. I would not have thought of battery power.

  13. Great new idea. If the system could be adapted to N and the cost was reasonable it would certainly put it to the DCC producers who are presently gouging for decoders and electronics. The idea of control without wiring is even closer to the real thing. Good show. Keep the information coming.

  14. Brilliant. That would have saved me a ton of frustration a time or two.

  15. Are you using a rechargeble battery?

  16. Can I use a similar system on my new Garden railroad? Can I use the same DC motor in my current engine and just add a controller?

  17. Check out the RC car hobby. There are lots of ideas to be gleaned from this quarter. That’s how I got started with my G scale stuff. I also have On3 trains running on batteries on a shunting puzzle layout I built for my grand kids. Coupling/uncoupling and switching is all done manually.

    RC gear for N gage is readily available, but it can get costly due to the miniaturization, but I predict it will soon be the norm for all scales.

  18. batteries WOW!
    A great invovation …

    More on this would be great. Same questions as all the others battery life and cost.

    Still I like it.

    Thanks Bob and Al



  19. Dirty track is dirty track and wheels will slip and stick and run poorly on it even if they’re not drawing power from it. Also this system could get expensive if the batteries do not last long, and will electric bills go down if they need to be frequently recharged?
    I dunno, it seems to me as if one might just give up the fuss of wiring (usually only once?) and track cleaning for the fuss of always changing and replacing and charging batteries?
    Time will tell I guess, but I’m in no hurry to give up the reliability of always available clean electrical power, and tracks will always have to be cleaned somewhat anyway…

  20. To all who asked;
    I researched this on the internet and found a great deal of information about radio control w/battery operation. Also, there are many groups that provide advise and help with this part of the hobby. You can also check out hobby shops and groups that work with radio controlled model cars, boats and planes. I picked the DRS1 system because I already had a DCC layout and wanted to use everything I already had installed. I elected to have my locomotive motors isolated from the wheels but this is not necessary especially if you want to run on battery or with track voltage as well. Although this may not be the solution for most, I am sorry I didn’t know about this technology a few years ago …. I could have saved a bundle and a whole lot of time wiring my layout.


  22. one guy asked if it would cut your elec bill down if you where charging the battery. Duh , if that is a problem then put a small solar panel out to recharge them. Other thing that you can add on is a side rail for charging and put a fullwave bridge recatifer in the system and power up a side rail just for charging AC/DC IT WOULD NOT MATTER if it was AC or DC with a fullwave rec. and they are very small

  23. if wired right you won’t need to worry if the rail polarity was right or not , cause the rec. works it out on its own. I had one on my CB radio cause the trucks I drove , I never knew the truck was – or + ground so the full wave rec took care of that problem for me.

  24. Hi Bob, I saw an HO train at one of the shows. I inquire about. The owner did it himself and suggest I do the same, because it takes some work and knolage, therefore will be expensive to have it made.
    I just have not the knwolage but with instructions I could do it.

  25. Some thoughts on the battery powered layout…
    1st… GREAT JOB!!!!!!!!!!
    2nd… For those that are interested, check out Dead Rail… on the web and on Facebook
    3rd…The first I experienced this was by observing an Athearn F7 A-B set with Hobbytown Drive… Don Feihman had brought the locomotive to an NMRA meet in Sacramento (About 1970) He also wrote an article on the locomotive that was published in Railroad Model Craftsman (about the same year). The radio equipment and controller were built by Mr. Feihman (An amateur radio enthusiast (Ham) and an electrical engineer. The most amusing thing about the locomotive was that it was built in the pre-digital age and used tonal controls. — For those who knew the tones and had a walkee-talkee set to the correct frequency, the locomotive could be controlled by whistling the correct pitch into the radio transmitter.

    All the best,

  26. I am not sure about larger scales but, n nscale you still need to clean the track. The dirt on the track builds up on the wheels of the rolling stock until it will no longer stay on the track. It is great for operation because dirty track does not cause poor or rough performance. I prefer my standard dcc because of weight. The radio control system requires the instalation of batteries in rolling stock and I have a mainline that has a maximium two percent grade. I like to pull one hundred plus cars on my trains and the batteries are just to much weight. I do keep an eye on the technology and as battries get smaller and lighter I may try it again in the future.

  27. The system — you mentioned that the “system plugs into your NCE DCC controller.” By “system” do you mean somehting off the shelf or did you ahve to jerry rig a connection to your dcc controller?

  28. Very interesting tell us more. Who sells the battery operated units

  29. can i convert my g scale trains there all outdoors and i can never get them to run good electricity thru track and i have to clean tracks everyday…help me please

  30. Good idea how much does it cost. John from MILWAUKEE WISCONSIN

  31. I had my G guage trains 3 of them on Battery with the batteries in a box car.Lithum batteries could run about 5 hours with out charging. Here in Fla with salt air and corrosion the batt were great. A very good experience.

  32. Hello there, You’ve done a fantastic job. I will certainly digg
    it and personally suggest to my friends. I’m sure they’ll be
    benefited from this website.
