I don't know how many 3rd Rail engines Matt has for comparison and no one else seemed to notice but in Matt's video at about 4:42 Matt blows the whistle. He does again as the train departs.
I have about 20 3rd Rail engines, all but one Santa Fe. Except for a Santa Fe (N&W)Y-3 and 3751 which had the real 3751 whistle with a QSI conventional sound set, all my engines (a 2-8-4, 2-10-2's, 2-10-4's, 4-8-2's, 4-8-4's, etc) sound the same. Matt's engine sounds different. The chuff sounds better and the whistle is different. If you go to 3rd Rail's website you can watch a Santa Fe 2900 Class video which has the sound set I have on my engines.
For those of you that have personal experience with 3rd Rail sounds, have you ever heard the sound set on Matt's engine before? Or, is it new?
For the record, I've done TMCC installations before, both Digital Dynamics and ERR and I am aware of the sound sets that have been offered for a number of years now. I just want to know if this is new.
