,@,@@,,,,@ 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 @,,,,,@@@@

,@@@@,@,,@ @@@@@@@,,,
,@,,,@@@,@ trains go by day and by night. along ,,,,,,,@,,

,,,,,,@@,, different parts of the railway have @@@@,,,@,,

,,,,,,@@@@ ,@,,@@,@,@
