Is there a way I can get a custom DCC Sound Decoder with the exact sounds as the real RDC-2 Coach-Baggage Car would?
Get a Loksound decoder, and record the sounds of an RDC from a tourist RR, then upload them to the decoder through your computer. I know of two railroads in New England who use RDCs.
Where's your location, because the TRE in the Dallas/ Ft. Worth, Texas runs some RDC-1's on occasion, although they're getting rarer.
