Well, I was only a kid :-)
The noise wasn't worse than that from electric fences though.

Yeah, I would expect your local radio-controlling governmental body
would get a little upset at an unlicensed transmitter on the airwaves :)

It's clear that Flyguy resents having his defects pointed out. Flyguy is correct to assert that I can't read the stuff he links to as supporting his moronic assertions. Nobody with functional reading comprehension could. His "reading comprehension" is the kind that skips over the text finding the bits he likes and ignoring the bits he doesn't like, and he's too dim to realise what he is doing.

As a kid I did something nasty. *Don't* try that at home.
I modulated high voltage spikes onto the voltage that went to the rails,
similar to electric fence pulses. No more problems with locomotives not
starting up or stalling. The pulses were strong enough to burn through
any dirt layer. Of course, listening to the AM band was, ahem, slightly
compromised.

Flyguy is great at reading material and deciding that it says exactly what he wants it to say.
He's got excellent self-indulgent reading comprehension. He's less good at comprehending what the text actually says. I've been noticing this for a few months now.

If you are too dim to comprehend what the text is actually saying, you can be dim enough to think it supports your point of view, even when it doesn't.

The power connection could be wireless, or it could emulate a fuel hose and be plugged into the fuel tank on the engine. Charge up the battery and it's ready for another trip. I guess you need someplace to put the batteries. Diesel trains don't have hopper cars anymore. They don't even have cabooses. The caboose is a red light fastened to the last car. I think it monitors pressure in the air hose.

The engine control could be RF which could be very small, a single 8 pin MCU plus the RF receiver which can be a single transistor and a coil I believe. They probably already have the remote RF and MCU unit. I expect the only real issue will be where to put the battery.

The jacks themselves are quite robust; but the models themselves really
aren't - I mean, we're talking detail parts that are 0.010" (0.25mm) in
a lot of cases.

The circuit board(s) can be made much smaller. They use multiple boards to reduce the design work, but an MCU can be used to consolidate some of the functions making the electronics much smaller.
