¨¨¨¨&&&¨¨¨ 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! ¨¨&¨&&¨¨¨&
