¨#¨¨#¨¨#¨# 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 ¨##¨#¨¨#¨#
¨#¨##¨##¨#            ARTIFICIAL CHASMS.            ¨¨#¨#¨##¨#
¨#¨¨#¨¨#¨#                                          ¨##¨#¨¨#¨#
¨#¨##¨##¨# 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. ¨##¨#¨¨#¨#

¨#¨¨#¨¨#¨# MANY  PEOPLE FOLLOW  THE  RAILS BY FOOT. ¨##¨#¨¨#¨#
¨#¨##¨##¨# OFTEN  THIS PROVES  TO  BE  THE  SHORTER ¨¨#¨#¨##¨#
¨#¨¨#¨¨#¨# PATH  BETWEEN  TWO POINTS. HOWEVER  THIS ¨##¨#¨¨#¨#
¨#¨##¨##¨# IS   FROWNED  UPON,  AND  VERY  IMPOLITE ¨¨#¨#¨##¨#
¨#¨¨#¨¨#¨#         TOWARD THE TRAIN DRIVERS!        ¨##¨#¨¨#¨#
