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!
