MU-ing TMCC and Legacy loco's

controller does not make a difference.  you just have to run the legacy unit as a TMCC.  with the legacy unit it is much easier to change from legacy to TMCC and back.  just follow the instructions in the engine manual to set it up as a TMCC.

Hi Andy,

You can select to run Legacy engines w/ Odessey II in either 32 or 100 speed steps in TMCC mode.  However, Odessey and Odessey II are not the same thing.  You can MU any two engines with Odessey II because they all use the same speed map.  Odessey engines really didn't have a defined speed map.  Some will match well and others will not.  See if you can test run your Odessey engine against an Odessey II engine in TMCC 32 mode at your LHS.  That will tell you if you'll be able to MU with any other Odessey II engine.

Legacy and odyssey engines is a crapshoot to get them to run together. I think the odds are better at Vegas! Unlike MTH engines that you can mu together with zero issues(I've seen Steamers running with diesels), I tried running a Legacy U30C with an odyssey engine with both having the same motor types and they won't play nice together. Cannot turn odyssey off as it is an earlier version with no switch. Had both engines in the front and/or rear and Vegas' odds won!
