¨§¨§¨§¨§¨§ 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.            ¨¨§¨§¨§¨§¨

¨§¨§¨§¨§¨§ 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. ¨§§¨§¨§¨§¨
