@¨@@¨¨@¨@¨ TRAINS  ARE  SO  CONSTRUCTED  THAT  THEY @¨@¨@¨@¨@¨
@¨¨@¨@@¨@¨ HAVE TO FOLLOW A SET PATH. THIS PATH  IS @¨@¨@¨@¨@¨
@¨@@¨¨@¨@¨ CALLED A "RAILWAY", WHICH  IS  COMPRISED @¨@¨@¨@¨@¨
@¨¨@¨@@¨@¨ OF  TWO METAL RAILS, HENCE ITS NICKNAME. @¨@¨@¨@¨@¨

@¨¨@¨@@¨@¨ BECAUSE THE  LOW  FRICTION  BETWEEN  THE @¨@¨@¨@¨@¨
@¨@@¨¨@¨@¨ WHEELS OF THE  TRAIN AND THE RAIL METAL, @¨@¨@¨@¨@¨
@¨¨@¨@@¨@¨ THERE  ARE LIMITS  FOR HOW ACUTE A CURVE @¨@¨@¨@¨@¨
@¨@@¨¨@¨@¨ CAN  BE,  AND  EVEN MORE SO FOR HOW MUCH @¨@¨@¨@¨@¨
@¨¨@¨@@¨@¨ THE  GROUND  UNDER  THE  RAILS  CAN   BE @¨@¨@¨@¨@¨
@¨@@¨¨@¨@¨ SLOPED.  THUS A RAILWAY IS OFTEN NOT LED @¨@¨@¨@¨@¨

@¨@@¨¨@¨@¨ RAILS,  BUT NOT TOO CLOSE,  OR THEY WILL @¨@¨@¨@¨@¨
@¨¨@¨@@¨@¨ BE  CUT  DOWN  BY THE  RAILWAY JANITORS. @¨@¨@¨@¨@¨
@¨@@¨¨@¨@¨ THERE  WILL  BE  PLAINS,  AND BODIES  OF @¨@¨@¨@¨@¨

@¨@@¨¨@¨@¨      THE WAY, THERE IS INFORMATION       @¨@¨@¨@¨@¨
@¨¨@¨@@¨@¨ SCATTERED,  OFTEN  PUT ON  TOP OF POLES, @¨@¨@¨@¨@¨
@¨@@¨¨@¨@¨ TO  BE INTERPRETED BY THE TRAIN DRIVERS. @¨@¨@¨@¨@¨
@¨¨@¨@@¨@¨ DIFFERENT  PARTS  OF  THE  RAILWAY  HAVE @¨@¨@¨@¨@¨
