¨¨^=^$$§£# trains  are  so  constructed  that  they #£§$$^=^¨¨
¨¨¨^=^$$§£ have to follow a set path. this path  is £§$$^=^¨¨¨
¨¨^=^$$§£# called  a "railway", which is  comprised #£§$$^=^¨¨
¨^=^$$§£## of two metal rails, hence  its nickname. ##£§$$^=^¨

¨¨¨^=^$$§£ because  the low  friction  between  the £§$$^=^¨¨¨
¨¨^=^$$§£# wheels of the train and the  rail metal, #£§$$^=^¨¨

¨¨¨^=^$$§£ the  ground  under  the  rails  can   be £§$$^=^¨¨¨
¨¨^=^$$§£# sloped. thus a railway is often  not led #£§$$^=^¨¨

¨¨^=^$$§£# tunnels  (if   they   are   large),   or #£§$$^=^¨¨
