SI Staff Use Smithsonian Metro Station Farecard Vending Machines, , Smithsonian Institution Archives, Caption from Torch: "Six hundred eighty-five Smithsonian staffers gathered in the new Metro station on June 17 for a guided tour and explanation of the system by Metro officials. The initiation must have helped because an unofficial count shows that delighted station users include many SI employees who had never ridden the Metro until the blue line opened on July 1. In the photograph, a group of employees try out an automatic farecard machine.".
