#¶@=†-~,,, 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 ,,~-†=@¶##

##¶@=†-~,, scattered, often put  on top  of  poles, ,,~-†=@¶##
