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!
