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

¨,,,~~~†$# there will be trees on the  side  of the #$†~~~,,,¨
¨¨¨¨,~†$## rails, but not  too close, or they  will ##$†~,¨¨¨¨
¨,~†§$#### be  cut  down by  the  railway janitors. ####$§†~,¨
¨,~†§$#### there  will  be  plains, and  bodies  of ####$§†~,¨

¨¨¨~~†$### trains  go  by day  and  by night. along ###$†~~¨¨¨
¨,~†§$####      the way, there is information       ####$§†~,¨
¨,~†§$#### scattered,  often put on  top  of poles, ####$§†~,¨
¨,~†§§$$## to be interpreted  by the train drivers. ##$$§§†~,¨
¨,~†§$#### different  parts  of  the  railway  have ####$§†~,¨

¨¨¨~~†$### for something to  happen, far away. this ###$†~~¨¨¨
¨¨¨¨¨,~§§# is  signaled  by  red  or green  lights. #§§~,¨¨¨¨¨
