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!
