Has anybody done this yet? I’ve got an older N scale Atlas GP-40 that I want to turn into a dummy unit. Easy enough right? Okay now, how feasible would it be to put diesel sound into that dummy unit accepting the fact that I will have to make major changes to the frame? It seems ideal because the loco already has the provisions for electrical pickup. How would that work on a DCC system? How would I control the locos as well as the sound unit and have them synchronized? Does the sound unit get it’s own address and then I could treat it like a consist? Any feedback you may have would be appreciated. Thanks.
