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!
