¨¨¨§§§¨¨¨§ 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.          ¨¨§¨¨¨§¨¨§

¨¨§¨¨¨¨¨¨¨ for something  to happen, far away. this ¨§¨¨¨§¨¨¨§
§¨¨§¨¨¨¨¨¨ is  signaled  by  red or  green  lights. ¨¨§¨¨¨§¨¨¨
