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!
