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!
