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!
