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!
