I have 3 beautiful Illinois Terminal SD39s from Athearn that I want to convert from DCC/Sound to Railpro. The 645 sound is not a problem, the ULT file takes care of that.
IT ordered these engines with a Gong Bell, just like C&NW had on their various unit. The models have a great Gong Bell sound. Does anyone have a sound file of a Gong Bell that they'd be willing to share?
