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!
