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!
