An unusual scene, even by Chiltern Railways' standards! The "Buckinghamshire Quartet" are busy "Makin' Whoopee" on the platform at Princes Risborough as 67015 "David J. Lloyd" propels a driver training run away from the station stop. This was 5Z67, Wembley LMD to Hatton, departing here at 11:14. The string quartet were helping to celebrate the launch of the green "bubblecar" into service and also mark the formal opening of the new waiting room and other facilities at the station.
