£¨£¨¨££££¨ 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!         ££¨¨£££££¨
