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!
