,£,,££,,£,                                          £,,££££££,
,,,,,,,,,, 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!         ££££££££££
