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!
