¨¨¨¨¨¨=^*& 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 ##&**^^=~¨
