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!
