On June 8, 1939, a royal train rolled into Track 20 at Union Station. The station had been cleaned and shined, the columns lining the track had a fresh coat of green and white paint, and a blue carpet was rolled out from the platform to the newly redecorated station reception room. The visitors arriving in Washington that day were King George VI and Queen Elizabeth, who made history by becoming the first reigning British monarchs to ever set foot on American soil. Of the various activities that the King took part in during his stay, the irony of his visit to Mount Vernon was, quite possibly, the most intriguing.
