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!
