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!
