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!
