Have you considered battery operation for some of the newer, easier to convert engines?
That would allow you to run to postwar stuff as they were intended to run with a transformer handle and give you the freedom to run the newer stuff right along with them.
I'll be honest, I do not know much at all about TMCC or Legacy. We had a few LionChief upgrades which are simple and run on track power but can easily be converted to battery.
I've put BlueRail in a conventional Atlas engine, Two MTH F3 PS3 engines and a Railking 2-8-0 running in Basic mode with no sound. The MTH engines run on battery power and the Atlas engine runs on Track Power along with the Lionchief engines. We also have traditional DCS and Legacy (My Sons). He has forbid me to mess with his Legacy Engine.
GunRunnerJohn here on the forum does a lot of TMCC upgrades and they seem simple enough to work with almost anything. But then you are into the "proprietary" system.
