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!
