-### How to drive trains
-(The non-pdf manual file got corrupted, one day I need to make a new manual. Meanwhile here)
-First of all: you can always get off the train with right-click.
-
-While on a train:
-W - faster
-S - slower / change direction 
-Space: brake
-Shift+S: set speed to 0 (train rolls out, brake to stop!)
-Shift+W: Set full speed
-Shift+A: Set speed to 4 (~40km/h)
-Shift+D: Set speed to 8 (~100km/h)
-Shift+Space: toggle brake
-Shift+Use: get off
