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!
