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!
