£$*:~^¨¨¨¨ trains  are  so  constructed  that  they ¨¨¨¨^~:*$£
$*:~^¨¨¨¨¨ have to follow a set path.  this path is ¨¨¨¨¨^~:*$
*:~^¨¨¨¨¨¨ 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       ¨¨¨¨¨¨^~:*
$*:~^¨¨¨¨¨ scattered,  often  put  on top of poles, ¨¨¨¨¨^~:*$
£$*:~^¨¨¨¨ to be interpreted  by the train drivers. ¨¨¨¨^~:*$£
#£$*:~^¨¨¨ different  parts  of  the  railway  have ¨¨¨^~:*$£#
##£$*:~^¨¨          different speed limits.         ¨¨^~:*$£##

##£$*:~^¨¨ sometimes, trains have  to stop and wait ¨¨^~:*$£##
#£$*:~^¨¨¨ for something to happen, far away.  this ¨¨¨^~:*$£#
£$*:~^¨¨¨¨ is signaled  by  red  or  green  lights. ¨¨¨¨^~:*$£

£$*:~^¨¨¨¨ many people  follow  the  rails by foot. ¨¨¨¨^~:*$£
#£$*:~^¨¨¨ often  this  proves  to be  the  shorter ¨¨¨^~:*$£#
##£$*:~^¨¨ path  between two  points.  however this ¨¨^~:*$£##
