@##$*†~^¨¨ trains  are  so  constructed  that  they ¨¨^~†*$##@
#@##$*†~^¨ have to follow  a set path. this path is ¨^~†*$##@#
@##$*†~^¨¨ called  a "railway",  which is comprised ¨¨^~†*$##@
##$*†~^¨¨¨ of two  metal rails, hence its nickname. ¨¨¨^~†*$##
#$*†~^¨¨¨¨                                          ¨¨¨¨^~†*$#
$*†~^¨¨¨¨¨ because  the  low  friction  between the ¨¨¨¨¨^~†*$
*†~^¨¨¨¨¨¨ 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 ¨¨¨¨¨¨^~†*
$*†~^¨¨¨¨¨ be  cut down  by the  railway  janitors. ¨¨¨¨¨^~†*$
#$*†~^¨¨¨¨ there  will be  plains,  and  bodies  of ¨¨¨¨^~†*$#

#@##$*†~^¨ trains  go by  day  and by night.  along ¨^~†*$##@#
@##$*†~^¨¨      the way, there is information       ¨¨^~†*$##@
##$*†~^¨¨¨ scattered,  often  put on top  of poles, ¨¨¨^~†*$##
#$*†~^¨¨¨¨ to be interpreted by the  train drivers. ¨¨¨¨^~†*$#
$*†~^¨¨¨¨¨ different  parts  of  the  railway  have ¨¨¨¨¨^~†*$
*†~^¨¨¨¨¨¨         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. ¨¨¨¨¨¨¨¨^~
