###¨#¨¨¨¨# 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 #¨##¨¨¨¨#¨
