¨¨,«:*$### trains  are  so  constructed  that  they ###$*:«,¨¨
¨¨¨,«:*$## have to  follow a set path. this path is ##$*:«,¨¨¨
¨¨,«:*$### called a "railway", which  is  comprised ###$*:«,¨¨
¨,«:*$#### of  two metal rails, hence its nickname. ####$*:«,¨
¨¨,«:*$###                                          ###$*:«,¨¨
¨¨¨,«:*$## because the  low  friction  between  the ##$*:«,¨¨¨
¨¨,«:*$### wheels of the train  and the rail metal, ###$*:«,¨¨
¨,«:*$#### there are limits for  how acute a  curve ####$*:«,¨
¨¨,«:*$### can be, and  even  more so for  how much ###$*:«,¨¨
¨¨¨,«:*$## the  ground  under   the  rails  can  be ##$*:«,¨¨¨
¨¨,«:*$### sloped. thus a railway  is often not led ###$*:«,¨¨
¨,«:*$#### on  top of hills, rather through them in ####$*:«,¨
¨¨,«:*$### tunnels   (if   they   are   large),  or ###$*:«,¨¨
¨¨¨,«:*$##            artificial chasms.            ##$*:«,¨¨¨
¨¨,«:*$###                                          ###$*:«,¨¨
¨,«:*$#### there  will be trees on the side  of the ####$*:«,¨
¨¨,«:*$### rails, but  not  too close, or they will ###$*:«,¨¨
¨¨¨,«:*$## be  cut  down by  the  railway janitors. ##$*:«,¨¨¨
¨¨,«:*$### there  will  be plains,  and  bodies  of ###$*:«,¨¨

¨¨¨,«:*$## trains go by  day  and by  night.  along ##$*:«,¨¨¨
¨¨,«:*$###      the way, there is information       ###$*:«,¨¨
¨,«:*$#### scattered, often put  on top  of  poles, ####$*:«,¨
¨¨,«:*$### to be interpreted by the  train drivers. ###$*:«,¨¨
¨¨¨,«:*$## different  parts  of  the  railway  have ##$*:«,¨¨¨
¨¨,«:*$###          different speed limits.         ###$*:«,¨¨
¨,«:*$####                                          ####$*:«,¨
¨¨,«:*$### sometimes, trains  have to stop and wait ###$*:«,¨¨
¨¨¨,«:*$## for something to happen, far away.  this ##$*:«,¨¨¨
¨¨,«:*$### is  signaled  by  red  or green  lights. ###$*:«,¨¨

¨¨,«:*$### many  people follow the  rails  by foot. ###$*:«,¨¨
¨,«:*$#### often  this proves  to  be  the  shorter ####$*:«,¨
¨¨,«:*$### path between  two points.  however  this ###$*:«,¨¨
¨¨¨,«:*$## is  frowned  upon,  and   very  impolite ##$*:«,¨¨¨
