§§¨¨¨¨¨§¨¨ 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.          ¨§§¨§§§¨¨¨

§§¨§§¨§¨§¨ sometimes, trains have to stop and  wait §§§§¨§¨§§¨
§¨§§¨§§§§§ for something to  happen, far away. this §¨¨¨§§§§¨§
¨§§¨§§¨¨¨¨ is  signaled  by  red  or green  lights. ¨§¨¨§¨¨¨§§
