¨¨§¨¨¨¨§¨§ 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 §¨¨¨§§§¨§§
