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!
