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!
