Very basic mod that provides startup settings for changing the Acceleration and Max Speed multipliers of Raw Wood, Coal, Solid Fuel, Rocket Fuel, and Nuclear Fuel. I felt my trains weren't killing players often enough, trains zooming by at 1000+ KPH solves that.
By default uses the base settings for the fuels, but both acceleration and max speed can be set anywhere from 0.1 (10%) to 10.0 (1000%). I tried experimenting with higher values, but trains approaching 3000KPH start to tank performance, so for now I've capped it at 1000%, which effectively limits trains to under 2600KPH, which is still ridiculously fast.
