Join me aboard 74 year-old London Transport AEC Regent III / Park Royal RT1790 (KYY 628) on route 145 to Barking, Fair Cross.
With pleasant engine tone and gearbox notes, RTs like this were a ubiquitous sight and sound familiar to Londoners from the 1940s up to 1979, but now an increasing rarity, enjoyable on special Running Days (and service 339 to the Epping Ongar Railway).
The bus was operating as part of the Barking Garage Centenary Running Day by the London Bus Museum.
