Thanks guys, well....at this point it seems it was a really bad mistake on my part to buy the 2 PWC sets, and frankly TMCC to a lesser degree.
For now on its Legacy and DCS or bust!
I say MTH DCS too, but it seems MTH has issues with PS3 transit and certain LIRR locos...and its not just me.
So, I am holding off on all MTH LIRR purchases except RS3s
Hopefully they will get it resolved, as frankly I like DCS even better than Legacy.
