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!
