#¨#####¨## 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!         ¨#¨¨¨####¨
