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!
