I'm committed to semi-scale for at least the next decade. Modern stuff is mainly TMCC (not legacy) with a handful of WBB conventional. About 1/3 of my motive power is PW (conventional, of course) inherited from Grandpa. Never adopted PS2/PS3. No need at this point.
I see LionChief Plus replacing TMCC for the semi-scale market, and I'm watching prices of "old" TMCC engines plunge on the aftermarket. This fits me as a bargain hunter.
Longer term, am I safe? My understanding is that:
1. As long as ERR is around, I could replace any TMCC electronics that crap out (which I figure could happen at some point).
2. If my command bases and CAB-1s crap out (I have a back-up of each), I could always buy Legacy and operate TMCC engines with Legacy.
It seems like I'm protected but I wanted to see if anyone has any other "insurance" ideas I should consider.
