Lovely app but please add presets for real trains such as the amazing sounding 1996 Stock!

Extremely useful with a lot of features. Perhaps add DTC (direct torque control) and Wide-11 pulses if possible

It's quite useful for VF drive enthusiasts like me to create new traction motor to the train, but otherwise it looks great, the only downside I experience (which was in new update) is the waveform acceleration, braking and cruising audio making Crackling and Popping noises that some people might complain like me, which is needed to fix a problem, other words, it needs another maintenance version which I didn't like the way crackling and popping sounds appear, otherwise, great app nevertheless!

Very nice simulation and easy to use. Suggestions: 1. Please allow the spread period of up to 200ms, so that I can recreate the Siemens Desire UK VVVF. 2. Increase maximum speed to 500 km/h. 3. Fully customize Throttle/Brake notches. 4. Add support of DTC/DSC.
