I'd a had more F's, but Intermountain screwed up the B units... Never fear, they're on order in the next batch. I had a good sized fleet of Bachmann spectrums and plusses, but they didn't make the transition to DCC. No matter what I tried, they burned out decoders left and right.
I'd also have more F's if someone would make the right damn decals for them. But I just ordered the WM font, so I'll do that myself if need be.
RS-3's and F's were probably the highest volume units they had, followed by the SD-40's. Everything else seemed to come four or five at a time. (I've only got to do one more FA-2 to round that fleet out, too...
