###¤£^†~^¨ 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 ¨¨¨¨^~†£¤#
