¨-~^$$¤¤££ trains are so constructed that they ££¤¤$$^~-¨
¨-~^$$¤£## have to follow a set path. this path is ##£¤$$^~-¨
¨-~^$$£### called a "railway", which is comprised ###£$$^~-¨
¨¨¨¨~~$$¤# of two metal rails, hence its nickname. #¤$$~~¨¨¨¨
¨-~^$$¤£## ##£¤$$^~-¨
¨-~^$$¤£## because the low friction between the ##£¤$$^~-¨
¨-~^$$£### wheels of the train and the rail metal, ###£$$^~-¨
¨¨¨--^$$¤¤ there are limits for how acute a curve ¤¤$$^--¨¨¨
¨¨¨¨¨¨~$$£ can be, and even more so for how much £$$~¨¨¨¨¨¨
¨¨¨¨¨¨¨~$¤ the ground under the rails can be ¤$~¨¨¨¨¨¨¨
¨-~^$$$¤¤£ sloped. thus a railway is often not led £¤¤$$$^~-¨
¨-~^$$$$$¤ on top of hills, rather through them in ¤$$$$$^~-¨
¨-~^$$¤¤¤# 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 ##£¤$$^~-¨

¨-~^$$¤££# scattered, often put on top of poles, #££¤$$^~-¨

¨-~^$$¤£## different parts of the railway have ##£¤$$^~-¨
