¨§§¨§¨§¨§§ 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 §§§§¨§§¨§§

¨§§§¨¨¨§¨¨ scattered, often  put  on top  of poles, §¨§¨§¨¨§§§
§¨¨§¨¨§§¨§ to be interpreted  by the train drivers. §§§§§¨§¨¨§
§¨§§¨§¨§§¨ different  parts  of  the  railway  have ¨¨¨¨§§§¨§¨
