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!
