§¨§¨¨¨§¨§¨ 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. §¨§¨§¨§§¨¨

¨§§¨¨§¨§§§ 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 ¨§¨§§§¨¨¨§

¨¨¨§§¨§§¨§ be  cut  down by the  railway  janitors. ¨§§§§§¨§¨§
§¨¨§¨§§¨§§ there  will  be  plains,  and  bodies of ¨§¨¨¨¨§§§§

§¨§§¨§¨¨¨§ to be interpreted by  the train drivers. ¨¨§§§§§¨¨¨
