I've hade a SEPTA AEM7 for ages, but this is a new one, since my old one hit the floor. I use the old one for spare parts. I might get an amtrak GG1 if i get an NEC style layout. otherwise i think i'm going to stick to my various E60s, AEM7s and HHP8s.
In other news, i casted my first detail part today, the big electrical box on the AEM7s, because they don't stock that spare part on atlas anymore.
