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!
