§¨§§¨§¨§¨§ 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. ¨§¨§¨§¨§§¨

§¨¨§¨§¨§¨§ the  ground  under  the  rails   can  be ¨§¨§¨§¨§§¨

§¨§§¨§¨§¨§ tunnels   (if   they   are   large),  or §§¨§¨§¨¨§¨
