¨¨,«^%%&@# 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 #@&%%^«,¨¨

¨,«^%%&@## be  cut  down by  the  railway janitors. ##@&%%^«,¨
¨¨,«^%%&@# there will  be  plains,  and  bodies  of #@&%%^«,¨¨

¨,«^%%&@## scattered, often  put  on  top of poles, ##@&%%^«,¨
¨¨,«^%%&@# to be interpreted by the train  drivers. #@&%%^«,¨¨
¨¨¨,«^%%&@ different  parts  of  the  railway  have @&%%^«,¨¨¨
