Thank you much guys!
I run some Conventional. My Legacy & TMCC Locos run via Legacy (no tiu/aiu/dcc/dcs etc). I guess I've just been really, really lucky through all the derails with the TMCC & Legacy Locos. I did grab a ZW-L that provides track power to the new permanent layout. I'll keep an eye on this thread and upgrade the protection on the pre/post transformers once you guys nail this down. Thanks again for your great work and service to the community.
