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!
