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!
