@¨@¨@¨@¨@¨ 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 @¨@¨@¨@@¨@

@¨@¨@¨@¨@¨ THERE  WILL BE TREES ON  THE SIDE OF THE @¨@¨@¨¨@¨¨
@¨@¨@¨@¨@¨ 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 @¨@¨@¨¨@¨¨
