#$†~,,,,,, trains  are  so  constructed  that  they ,,,,,,~†$#
$†~,,,,,,, have to  follow a set path. this path is ,,,,,,,~†$
†~,,,,,,,, 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. ,,,,,,,,~†

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