¨¨¨¨§§§¨¨¨ 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 ¨¨¨¨¨¨¨¨¨§

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

¨¨¨§¨¨§§¨¨ to be interpreted  by the train drivers. ¨¨¨¨§¨¨§§¨
§§¨¨¨¨¨¨¨¨ different  parts  of  the  railway  have ¨§§¨¨¨¨¨¨¨

§§§§¨¨§§§§ for something to happen, far  away. this ¨§§§§¨¨¨§§
