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!
