¨§¨¨¨§§§§§ 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 §¨¨¨¨§§§¨§

¨¨§¨¨¨§§§¨      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 ¨§¨§§¨¨¨§§
