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!
