,,,,£,,,££ 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!        ,,,£,,,£££
