¨§¨§¨¨§¨§¨ 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 §¨§¨§¨§¨§§
