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!
