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!
