#¨##¨#¨#¨# 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 #¨#¨#¨#¨#¨
#¨¨#¨#¨#¨# ON TOP  OF HILLS, RATHER THROUGH THEM IN #¨#¨#¨#¨#¨
#¨##¨#¨#¨# TUNNELS   (IF  THEY   ARE   LARGE),   OR #¨#¨#¨#¨#¨

#¨¨#¨#¨#¨# 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 #¨#¨#¨#¨#¨
#¨¨#¨#¨#¨#                  WATER.                  #¨#¨#¨#¨#¨

#¨¨#¨#¨#¨# TRAINS  GO  BY DAY  AND BY  NIGHT. ALONG #¨#¨#¨#¨#¨
#¨##¨#¨#¨#       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 #¨#¨#¨#¨#¨
#¨##¨#¨#¨#          DIFFERENT SPEED LIMITS.         #¨#¨#¨#¨#¨

#¨##¨#¨#¨# SOMETIMES, TRAINS HAVE TO STOP  AND WAIT #¨#¨#¨#¨#¨
#¨¨#¨#¨#¨# FOR SOMETHING  TO HAPPEN, FAR AWAY. THIS #¨#¨#¨#¨#¨
#¨##¨#¨#¨# IS  SIGNALED  BY  RED  OR GREEN  LIGHTS. #¨#¨#¨#¨#¨

#¨##¨#¨#¨# PATH BETWEEN  TWO  POINTS.  HOWEVER THIS #¨#¨#¨#¨#¨
#¨¨#¨#¨#¨# IS   FROWNED  UPON,  AND  VERY  IMPOLITE #¨#¨#¨#¨#¨
