£$*==-¨¨¨¨ trains  are  so  constructed  that  they ¨¨¨¨-==*$£
$*==-¨¨¨¨¨ have  to follow a set path. this path is ¨¨¨¨¨-==*$
*==-¨¨¨¨¨¨ called a "railway",  which is  comprised ¨¨¨¨¨¨-==*

#£$*==-¨¨¨ the  ground  under   the  rails  can  be ¨¨¨-==*$£#
£$*==-¨¨¨¨ sloped. thus a railway is  often not led ¨¨¨¨-==*$£
$*==-¨¨¨¨¨ on top of hills, rather through  them in ¨¨¨¨¨-==*$
*==-¨¨¨¨¨¨ tunnels  (if   they   are   large),   or ¨¨¨¨¨¨-==*
