#££%;=^¨¨¨ 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!         ¨^=;%££###
