¨¨¨¨¨~«=$¤ trains are so constructed that they ¤$=«~¨¨¨¨¨
¨¨¨¨¨¨~«=$ 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 «~¨¨¨¨¨¨¨¨

¨¨¨¨¨¨¨¨¨¨ ¨¨¨¨¨¨¨¨¨¨
¨¨¨¨¨¨¨¨¨¨ sometimes, trains have to stop and wait ¨¨¨¨¨¨¨¨¨¨
