Rails                  
                                          
                                          
  
                                          
  
                                          
                                          
 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!
