 0 - 9     Selects the power handle setting upto the maximum for the given
           train.
 >         Advance the Power handle one position (Notch up).
 <         Reduce the Power handle one position (Notch down).
 Q         Moves the brake handle back one position.
 W         Moves the brake handle forward one position.
 SPACE     Cancels the AWS.
 O         Resets an overload or overspeed trip.
 P         Pause the game.
 R         Recommence a paused game.
 F         Speed up the clock while the train is waiting.
 X         Exits the simulator - must be paused for this to work.

 All keys should work in either lower or upper case, except X which will
 only work as upper case, as a safety feature.

 Most of the controls are straightforward to use. The braking mechanism may
 seem a little strange at first, but will improve with practice.
