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!
