£££,,,££££ 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!         £,,£,,,,,£
