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!
