See...Complicated! I did not know all these differences. So any MTH engine can be a DCC engine with the change of a switch? Haven't bought an engine recently so must have forgot the existence of the DCD/DCC switch. Sorry for the bad info.
I was misled by Lionel marked sets sold by MTH with both the MTH remote control and Proto-3 DCS control. I assumed Lionel only sets were the same. Seems it is not so!
