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!
