¨¨¨¨--†*&# 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. ####&*†--¨
¨¨--†*&###                                          ###&*†--¨¨
¨¨¨--†*&## because  the  low  friction between  the ##&*†--¨¨¨
¨¨¨¨--†*&# 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 ###&*†--¨¨

¨¨¨--†*&## be cut  down  by  the  railway janitors. ##&*†--¨¨¨

¨¨¨¨--†*&#       the way, there is information      #&*†--¨¨¨¨
¨¨¨¨¨--†*& scattered,  often  put on top of  poles, &*†--¨¨¨¨¨
¨¨¨¨--†*&# to be interpreted by  the train drivers. #&*†--¨¨¨¨
