££,,,,,,£, 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!         ,,,£,££,,,
