##¨#¨¨¨¨#¨ 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!        ###¨¨#¨¨#¨
