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!
