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!
