#¨¨#¨####¨ 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 ¨###¨¨¨¨#¨

#¨¨¨#¨###¨ THE  GROUND  UNDER   THE  RAILS  CAN  BE ###¨##¨¨#¨
##¨¨###¨¨# SLOPED. THUS  A RAILWAY IS OFTEN NOT LED ¨¨¨##¨#¨##
¨¨#¨#¨¨#¨# ON TOP OF HILLS, RATHER THROUGH THEM  IN #¨¨#¨####¨

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

¨###¨¨¨¨¨¨ SCATTERED, OFTEN PUT  ON TOP  OF  POLES, #¨#¨¨##¨##
##¨¨#¨¨¨¨¨ TO BE INTERPRETED BY  THE TRAIN DRIVERS. ####¨#¨##¨
#¨#¨##¨¨¨¨ DIFFERENT  PARTS  OF  THE  RAILWAY  HAVE ¨¨¨¨####¨#
