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!
