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!
