¨§¨§¨¨§¨§¨ 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 ¨§¨§¨§¨§§¨
