...~;$@#@# trains are so constructed that they #@#@$;~...
....~;$@#@ have to follow a set path. this path is @#@$;~....
...~;$@#@# called a "railway", which is comprised #@#@$;~...
..~;$@#@## of two metal rails, hence its nickname. ##@#@$;~..
...~;$@#@# #@#@$;~...
....~;$@#@ because the low friction between the @#@$;~....
...~;$@#@# wheels of the train and the rail metal, #@#@$;~...
..~;$@#@## there are limits for how acute a curve ##@#@$;~..
...~;$@#@# can be, and even more so for how much #@#@$;~...
....~;$@#@ the ground under the rails can be @#@$;~....
...~;$@#@# sloped. thus a railway is often not led #@#@$;~...
..~;$@#@## on top of hills, rather through them in ##@#@$;~..
...~;$@#@# tunnels (if they are large), or #@#@$;~...
....~;$@#@ artificial chasms. @#@$;~....
...~;$@#@# #@#@$;~...
..~;$@#@## there will be trees on the side of the ##@#@$;~..
...~;$@#@# rails, but not too close, or they will #@#@$;~...
....~;$@#@ be cut down by the railway janitors. @#@$;~....
...~;$@#@# there will be plains, and bodies of #@#@$;~...
..~;$@#@## water. ##@#@$;~..
...~;$@#@# #@#@$;~...
....~;$@#@ trains go by day and by night. along @#@$;~....
...~;$@#@# the way, there is information #@#@$;~...
..~;$@#@## scattered, often put on top of poles, ##@#@$;~..
...~;$@#@# to be interpreted by the train drivers. #@#@$;~...
....~;$@#@ different parts of the railway have @#@$;~....
...~;$@#@# different speed limits. #@#@$;~...
..~;$@#@## ##@#@$;~..
...~;$@#@# sometimes, trains have to stop and wait #@#@$;~...
....~;$@#@ for something to happen, far away. this @#@$;~....
...~;$@#@# is signaled by red or green lights. #@#@$;~...
..~;$@#@## ##@#@$;~..
...~;$@#@# ######## #@#@$;~...
....~;$@#@ @#@$;~....
...~;$@#@# many people follow the rails by foot. #@#@$;~...
..~;$@#@## often this proves to be the shorter ##@#@$;~..
...~;$@#@# path between two points. however this #@#@$;~...
....~;$@#@ is frowned upon, and very impolite @#@$;~....
...~;$@#@# toward the train drivers! #@#@$;~...
