¨§¨¨§§§§§§ 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 ¨§¨§§§¨§§§

¨¨§¨§§¨¨§§ 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 ¨§¨¨§¨¨§¨¨
