I'm needing to get information on what decoders, both dcc and sound that will fit in HO scale Bachmann gp40s. Without a lot of frame butchering.

I would go with a Lenz Gold or Silver small enough for N scale but powerful enough for HO. Hardwire install but not that difficult. And well worth the time and effort

NCE has dedicated decoder for bachmans. it is a direct replacement of factory light board. no sound thoguh...
