#@@&$*\~^, trains are so constructed that they ,^~\*$&@@#
#@@&$*\~^, have to follow a set path. this path is ,^~\*$&@@#
#@@&$*\~^, called a "railway", which is comprised ,^~\*$&@@#
&***\~~,,, 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 ,^~\*$&@@@
