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!
