¨¨¨§¨¨¨§¨§ 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 §¨§¨§§§§§§
