#¨¨¨¨¨¨¨¨¨ 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 ¨######¨##

#¨¨¨###### 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. #¨##¨###¨¨
