Last weekend not only saw the Cobham rally, but also a celebration event for the 60th anniversary of the route 109 and Arriva London's Thornton Heath bus garage in south London on saturday 9th. To mark the occasion, Arriva London took four of their Routemasters, gold RM6, RML901, RMC1453 and RM2217, from their heritage fleet to run special services on the 109 throughout the day.
