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!
