#¨#¨#¨##¨# 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!         #¨##¨#¨#¨#
