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!
