Video of London Buses route 66 in Double Deck operation.

You may be interested that I have captured video of route 66 in action. It uses Wright Gemini 2 VDL DB300 where it was based from Clapton garage (CT). The bus is now currently in Grays (GY) for route 66 and briefly on route 370.

You may notice with the double decker routes operated from Grays Garage, you may notice they mix their double deck fleets on route 66 and 370, it does not mean it's official allocation as you see on London Vehicle Finder.
