¨¨¨£¨¨£¨¨£ 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 ££¨¨¨£££££
¨¨£££¨££¨£         toward the train drivers!        ¨¨£¨¨£¨¨¨¨
