The flagship route of the Oatford map is arguably the route 90, and what better than Studio Polygon's Enviro 400MMC to drive it with today. It may not fit the area but for one day only, the route gets the Sapphire treatment from Arriva.
(I failed to recognise that the market was where you are supposed to change the destination board before going back, so I terminated the route on the narrow bridge instead. Oops.)
