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!
