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 
 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!
