##&%**~:¨¨ 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! ¨¨:~**%&##
