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!
