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!
