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!
