Richie C. posted:As Ed stated, for command control operation, the DCS system (TIU and remote and/or Wifi) , will allow you to operate both MTH engines and Lionel TMCC and Legacy engines using the DCS controller (with potentially reduced features).
However, the reverse is not true. The Lionel TMCC or Legacy system will not allow you to run MTH/DCS engines - you can only run Lionel TMCC or Legacy engines.
You can operate full featured TMCC/Legacy engines and MTH/DCS engines on the same layout by installing both systems, because they are compatible for installation on the same layout.
Obviously, the above does not take into account conventional, non-command operation and control of engines with either system.
To clarify if you want to operate TMCC/Legacy locomotives with the DCS remote or DCS app you need a Lionel TMCC base or Legacy base and a MTH adaptor cable (https://mthtrains.com/50-1032). I have the cable connected from my TIU to my TMCC command base and run my DCS and TMCC locomotives from my DCS remote. I only use the Cab-1 on occasion, mostly for programming the radio boards in the locomotive. I find it easier to run everything from one remote.
