#&^†=~¨¨¨¨ trains  are  so  constructed  that  they ¨¨¨¨~=†^&#
##&^†=~¨¨¨ have to  follow a set path. this path is ¨¨¨~=†^&##
###&^†=~¨¨ called a "railway",  which is  comprised ¨¨~=†^&###

#&^†=~¨¨¨¨ wheels of  the train and the rail metal, ¨¨¨¨~=†^&#
&^†=~¨¨¨¨¨ there  are limits  for how acute a curve ¨¨¨¨¨~=†^&

†=~¨¨¨¨¨¨¨ 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 ¨¨¨¨¨¨¨¨¨¨
