,£££££££,, 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!         £,,££££££,
