MTH PS3 and Lionel TMCC compatibility

Yes, if you are referring to the current incarnation of the powermaster (or TPCs).  The original powermaster from 1994 or so may not work

all that well.  PS1 and, if I recall correctly, PS2,  did not play well with the original powermaster.

So I can replace my original Powermaster with a Legacy Powermaster and I'm good to go?

Yep, that will do it.

I have the original Powermaster on my layout (as well as a TPC400), and I don't run conventional much, but my Powermaster has a problem only with PS1 units, and it will run these - but the Proto-sound portion is quiet or funky in its nature (crazy chuffing; bell/whistle confusion or silence)

My experience, further:

The TPC400 will run PS1 just fine.

The old Powermaster and TPC400 will run PS2 and PS3 just fine. I don't have much PS3.

I have a couple of old, old PS1 locos still not upgraded to ERR - Premier ATSF 4-8-4 and Southern Ps-4 4-6-2 - that will run only on a Lionel Post War transformer, regardless of the throttle (P'master/TPC400). They won't even run on a Z-1000 using the Z-1000 throttle. Lionel 1033? Fine.

This whole area of early compatibilities is rife with variations. 

Thanks, guys.

I am not sure how PS-3 will do with TMCC. However I know that the Lionel CW-80 transformer can not be used with MTH PS-2 engines as it causes them to act crazy  and stay in one place, made that mistake one time at a friend's house.

It should be possible to run MTH PS-2 engines with most Lionel transformers in the regular mode only. Lionel's TMCC and MTH PS-2 don't work together unless you have both systems hooked up together.
