Severn posted:So vague-ish ideas, but untried ... if you are using DCS, you can use Mark Divecchios RTC program (or pieces of it) to possibly continuously poll the engines state and get some sense of what it is doing -- or if you were just using it (RTC) as the control -- you would in theory know what the engine has been commanded to do -- and therefore any slave sound systems could be put into the right state by the computer mirroring the master engine ...
I would guess that another stationary spare PS board could be programmed into the train and would throttle exactly the way the train does. It would be connected directly to a sound system.
That's what I used to do in HO. I only ran one train though!
