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!
