§¨§§§§§§§§ 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. ¨¨§¨§§§¨¨¨

¨§¨¨¨¨§¨¨¨ 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 ¨§§¨§¨¨¨§§

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