§§¨¨§¨§¨§¨ 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 §¨§¨§¨§¨§¨
§§¨¨§¨§¨§¨ path  between two  points. however  this §¨§¨§¨§¨§¨
¨§¨§§¨§¨§¨ is  frowned  upon,   and  very  impolite §¨§¨§¨§¨§¨
