##@&£*^-^, 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. ,,,,^-^*£&
£*^-^,,,,,                                          ,,,,,^-^*£

*^-^,,,,,, 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 ,,^-^*£&@#
