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!
