§¨¨§§§¨§§§ 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 §§¨¨§§¨¨¨§
