I have in my USA GP 38 the excellent Sierra sound system from TOC, Dave Goodman. Everything he sent me works great and it is L-O-U-D and s-o-f-t per the rheostat sound control. Apparently, the entire diesel operation is captured on the Sierra sound chip – warmup, yard speed, and the main line sounds.
OK, Sierra has come and gone – I doubt it available – what are quality, reliable, brands of sound systems readers of this site have both used and trust?
Here are some likely locos considered for sound:
USA’s diesels
Bachmann’s Annie, Connie, mallet (small number sold?), and the Forney.
LGB retro-fit in their steamers
Aristo’s mallet, Pacific and diesels.
What has been omitted, fine, tell us about the brand and your application.
