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!
