37047 accelerates away from Wraysbury, returning from Windsor & Eton Riverside, with the Pathfinder Tours 1Z91 'Buffer Puffer - The Return!' railtour on 20 March 2004. With so few Class 37s left in service with EWS at the time, it must have been quite an achievement to get two Mainline blue locos for the tour - 37203 was on the rear working top'n'tail. The train is just approaching a footpath crossing, and although not apparent here, the whole area on both sides of the line consists largely of lakes.
