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!
