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!
