§¨§§¨§¨§¨§ 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.          §¨§¨§¨§¨§¨

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