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!
