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!
