¨¨~==*&£## 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! £&*==~¨¨¨¨
