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!
