It's no problem, converting the train to BVE 2/4 is only a matter of speeding up the sounds and changing the .dat file. The R142 now makes propulsion sounds quicker, and the R142A has a deeper pitch, matching acceleration/deceleration sounds & no more repeating sounds. I'll be releasing version 6 later today while the BVE 2/4 versions will be released this weekend.
Does anyone have a file of the R142 making that hissing noise when it speeds and slows down?
