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!
