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!
