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!
