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!
