&¨&¨¨&¨&¨¨ 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! &¨&¨&¨&¨&¨
