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!
