The London Transport Museum buses that attended the event at North Weald were the first prototype Routemaster RM1 and Leyland Fleetline DMS 1.
RM1 is seen here alongside RT 1 from the London Bus Museum.
RM 1 operated one return passenger journey on route 339 between North Weald and Ongar - 'Two Brewers', carrying near capacity loads. Otherwise the buses were on static display, along with many other "Number Ones" and other unique or unusual preserved vehicles.
