HINTS:

THE REPAIR CAR NOT ONLY REPAIRS YOUR ENGINES,
BUT  CAN  ALSO  SET  UP A RAILROAD MINE. USE
THIS IMPORTANT ABILITY.

SELECT  THE  REPAIR CAR, PRESS THE SHIFT KEY
(THE  POINTER  WILL  CHANGE  ITS  SHAPE) AND
CLICK  AT  THE RAILROAD WITH THE RIGHT MOUSE
BUTTON.   THE  REPAIR  CAR WILL MOVE TO THIS
SPOT  AND  SET  UP  A MINE. REMEMBER THAT IT
TAKES SOME TIME TO SET A MINE.
