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!
