¨§¨¨¨¨¨¨¨¨ 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. §¨§§¨¨¨§§§

¨§§§¨¨§¨§§ many people follow  the  rails  by foot. §§¨¨§¨§§¨¨
¨§¨§§¨¨¨§§ often  this  proves  to  be the  shorter ¨§§¨¨¨§§§¨
