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!
