+### 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
+
+
