§¨¨§¨§§§§¨ 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. §¨§¨¨§§¨¨§
