####$$†«-¨ trains  are  so  constructed  that  they ¨-«†$$####
####$$†«-¨ have to follow a set path. this  path is ¨-«†$$####
####$$†«-¨ called  a "railway", which is  comprised ¨-«†$$####
##$†--¨¨¨¨ of  two metal rails, hence its nickname. ¨¨¨¨--†$##

#$$«««¨¨¨¨ because  the  low  friction  between the ¨¨¨¨«««$$#
##$$$$†«-¨ wheels of  the train and the rail metal, ¨-«†$$$$##
#$††«¨¨¨¨¨ there  are limits for how acute  a curve ¨¨¨¨¨«††$#
####$$†«-¨ 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 ¨-«†$$$###
