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!
