§§¨¨§§§§§¨ 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.            ¨§¨¨¨¨¨§§§

§¨¨¨§¨¨§§¨ 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.          §§¨¨§¨§§§§

§¨§¨¨¨§§§§ for something to happen,  far away. this ¨¨§¨§§¨¨¨¨
