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!
