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!
