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!
