####$†~^¨¨ trains  are  so  constructed  that  they ¨¨^~†$####
###$†~^¨¨¨ have to follow a set  path. this path is ¨¨¨^~†$###
####$†~^¨¨ called a  "railway", which is  comprised ¨¨^~†$####
#####$†~^¨ of two metal rails, hence  its nickname. ¨^~†$#####
####$†~^¨¨                                          ¨¨^~†$####
###$†~^¨¨¨ because  the low  friction  between  the ¨¨¨^~†$###
####$†~^¨¨ wheels of the train and  the rail metal, ¨¨^~†$####
#####$†~^¨ there  are limits for how acute a  curve ¨^~†$#####
####$†~^¨¨ can  be, and  even more so  for how much ¨¨^~†$####
###$†~^¨¨¨ the   ground  under  the  rails  can  be ¨¨¨^~†$###
####$†~^¨¨ sloped. thus a railway is often not  led ¨¨^~†$####
#####$†~^¨ on  top of hills, rather through them in ¨^~†$#####
####$†~^¨¨ tunnels   (if   they   are   large),  or ¨¨^~†$####
###$†~^¨¨¨            artificial chasms.            ¨¨¨^~†$###
####$†~^¨¨                                          ¨¨^~†$####
#####$†~^¨ there will be  trees on  the side of the ¨^~†$#####
####$†~^¨¨ rails, but not  too close, or they  will ¨¨^~†$####
###$†~^¨¨¨ be  cut  down  by  the railway janitors. ¨¨¨^~†$###
####$†~^¨¨ there  will  be  plains,  and  bodies of ¨¨^~†$####
#####$†~^¨                  water.                  ¨^~†$#####
####$†~^¨¨                                          ¨¨^~†$####
###$†~^¨¨¨ trains  go  by day  and by  night. along ¨¨¨^~†$###
####$†~^¨¨      the way, there is information       ¨¨^~†$####
#####$†~^¨ scattered, often put  on top  of  poles, ¨^~†$#####
####$†~^¨¨ to be interpreted by  the train drivers. ¨¨^~†$####
###$†~^¨¨¨ different  parts  of  the  railway  have ¨¨¨^~†$###
####$†~^¨¨         different speed limits.          ¨¨^~†$####
#####$†~^¨                                          ¨^~†$#####
####$†~^¨¨ sometimes, trains have  to stop and wait ¨¨^~†$####
###$†~^¨¨¨ for something to happen,  far away. this ¨¨¨^~†$###
####$†~^¨¨ is signaled  by  red  or  green  lights. ¨¨^~†$####
#####$†~^¨                                          ¨^~†$#####

####$†~^¨¨ many  people  follow the  rails by foot. ¨¨^~†$####
#####$†~^¨ often  this  proves  to  be the  shorter ¨^~†$#####
####$†~^¨¨ path between  two points.  however  this ¨¨^~†$####
###$†~^¨¨¨ is  frowned  upon,   and  very  impolite ¨¨¨^~†$###
####$†~^¨¨         toward the train drivers!        ¨¨^~†$####
