¨¨§¨§§¨¨§¨ 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.         ¨¨§¨¨§¨¨¨¨
