,£,,,,,,,, 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 ,,,,£,,,,,

,,,,,£,££, Rails,  But Not Too Close, Or  They Will ££,,,,,,£,
,,,,,,,£££ Be Cut  Down By  The  Railway  Janitors. £££,,,,,,£
£,,,,,,£,£ There  Will  Be  Plains, And  Bodies  Of £,££,,,,,,

,,,,£,,,,,       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 £,,,£,,,££

£££,,,,,,£                                          ,,£,,,£,,,
£,££,,,,,, 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 ,,,£££,,,£
