Sounds great! You nailed the initial acceleration spot on, however there are a few pointers I would like to give.
1. The initial notes you got spot on, but something just sounds a little off after the 25 mph mark and onward. The pitch seems a bit off, maybe you could look into that before release. Might be just me though.
2. The deceleration needs a bit more work. I think it has something to do with the pitch, but when 32 (C)s decelerate the pitch is high and it sounds like a 44 decelerating and it's also more dramatic. Then again, your 32 might be different from whatever phases are on the (C) today.
3. In real life, at around the 3mph mark when the train is decelerating, 32s slide and make a distinctive break noise along with a powerful jerking motion (insert joke here
). Maybe you can set that noise as part of the deceleration motor like what you did with the Siemens.
Other than that, the rest of the sounds you got right! Great job, typical of an error product!
