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!
