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!
