,,,£,,,,,, 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!        ££,,,,£,,,
