A typical battery is approx 1"x1"x5" long and fits inside the tenders of my steam engines.
My diesels all have them under the shell usually with the Rx sitting on top.

The ONLY complaint I have is there's no sound.
It's not so much a complaint as it is a side note, I don't like a lot of sounds coming from my engines.
I wouldn't mind having steam chuff or diesel rumble but couldn't care less for horns, bells, whistles.

I do have 2 engines with the BlueRail board installed,
and have 1 with a bluetooth speaker hooked up so the sounds come from the engine instead of my Ipad, pretty cool!

Hello Bob.

Please remember there MUST be a suitable dropping resistor in one leg of each LED.
470R up to 1KR will be OK.

Not needed with incandescent bulbs but the bulb voltage must match or preferably, exceed the battery supply voltage.

RX65b instructions

Hey Tony!!

You are correct, the LEDs I buy already have the resistor wired in. 
I get them from here:

LEDS

I've been running BPRC for 4+ years now and have had ZERO failures with any of the components from RCS (thanks Tony!) or DelTang. 
If you go to the other train forums you'll see 1/2 of the topics are about problems folks are having with their "systems". 
It was an expensive route I took (replacing 2 systems for 1) but IMO well worth the trip!!!

Bob,

Thank you for the diagram. It really helps to get it all straight in my head.
I think I'm going to use RX60s or RX61s as they are what the US dealer (On30guy) carries. 

Thank you also for the battery sizes.
Now that Christmas is over and the businesses are starting up again, I am going to order some bits.
I now have eight locos (received two for Christmas) and I will convert one or two to "get my feet wet".

I finally moved to DCC seven years ago when my DC pack decided to retire, and since I have a small layout, the wiring is not a problem.
When I started posting here I started reading many threads here from people using BPRC.
The more I thought about it and the more I thought about the myriad wiring problems of DC-type circuits and the problems of track pickup,
the more convinced I am that BPRC is really the best solution.

Unfortunately, a Bachmann On30 2-6-0 is my largest engine, in fact, it is too big for my layout.
I only have two tender engines, both 4-4-0s.
Getting my head around the sizes of the equipment and the available space inside my locos,
seems to be a challenge that can only be solved by buy-and-try.

I thought about the sound issue, one of my Porter 2-4-0s has sound,
and I decided that while I like it I usually end up muting the engine after a while.
Whole layout sound may be the answer if I find I miss it.
The idea of the Bluetooth speaker is rather intriguing. It sounds like a very cool solution.

My first conversion will be a Porter 2-4-0 since I already have it partially disassembled to install a DCC decoder.

This has not been an easy choice for me as my DCC works fine but I just don't see it as the future.
Things would have been easier and we would probably be further along if we had stayed with 3-rail AC and just added a third rail to the prototypes.

Tony,

Thanks for the note to Bob about LEDs, I was a little confused on that point.
My first conversion will have an incandescent light but most of my engines are LED.

Tony, I just followed the link to your web site. Very informative.
I am learning a lot about the various options out there thanks to you. 

Tom

In a show of support for my decision to pursue a BPRC layout, my wife bought me my first BP (unfortunately, non-RC) train for Christmas.





It actually also has a tender but it has "pins" on both ends instead of the requisite pin on one end and loop on the other.

The little train did serve to bring home several ideas.
The first is that even though this engine has no speed control, in every other way it is totally equal to the same train on DC or DCC.
Good speed control was the differentiator until we started using proportional control with battery power.
The other is that BPRC does not have to be complex.
I have been doing a lot of over-thinking.

Tom

Hello Tom.

Whilst I specialise in scales of full size 0 and above, the basic principles remain the same.
Just that with the larger scales they draw a lot more power rendering voltage up regulators not really worth the trouble.
They generally do have a lot more room for high capacity batteries.
Consequently I know very little about regulators and their operation.

Bob D has been helpful to me in understanding more about the smaller scales.
I doubt I will ever get involved in BPRC for the smaller scales.
I have my hands full with Large Scale Live Steam and battery power,
but, I can recommend dealing with Micron R/C for anything that is smaller.

I'll 2nd what Tony says about Micron.

If Tony doesn't have what I need I usually go to Micron for the rest, they deliver quickly to the U.S.

Tony and Bob,

Thanks for the reference to Micron. I will look at their site. I'm not finding exactly what I want locally.

I too use Micron Radio Control in the UK. 

Excellent source of DelTang supplies, and very helpful. 

I live in Australia.
