I have a few quick questions for ya and I don't mind a long winded answer, in fact it is encouraged:
Will a TMCC controlled steam loco run at the same speed in a consist as a TMCC diesel?
I don't have a lot of TMCC operating experience, all of my Lionel stuff is Legacy based. I have one TMCC diesel and it wouldn't run in a consist with my legacy diesels. I didn't try changing the control format in the remote, I just figured that was the way it is I have a lot of step grades on my layout and a single steam loco won't pull more than a dozen cars up the hills so, I convert a small diesel loco into a powered box car and run it as a consist. I am considering an older Lionel TMCC PRR T-1 to pull my GGD fleet of modernism cars. I have a TMCC RS-11 that would get the "box car treatment" to help pull it up the hills.
