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!
