¨¨¨§¨¨§§§¨ 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. ¨§¨¨§§¨¨§¨

§¨¨¨§¨§¨¨¨ 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 ¨¨§¨¨¨§§¨¨
