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!
