Hey RRMods team! I recently downloaded the SP, UP, UB and CEFX AC4400CW's from the N3V Store as part of the Christmas DLC deal. I had watched a video on these beforehand and while moving at high speed the engines seemed to make a whine sound that grew louder as speed increased. When I tried this, the train would get faster and faster but no whine was emitted. I'm at full throttle, in DCC and Cab Mode and this doesn't happen. Can anyone help me? Thank you!
