,,,£,,,,,, 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 ,,£,,,,,£,
