£¨¨¨¨¨¨¨¨¨ 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!        ¨¨¨¨£££¨¨¨
