LNER Gresley rebuild of a GER Claud Hamilton D16 class 4-4-0. Andy Rush has informed me that no. 8821 is hauling a local train arriving at the down Through platform at Ilford, passing under York Road footbridge (No.78) with Ilford West signal box behind the train. When I first showed it on the web a decade ago Ian Bowskill suggested that this shot was taken in the early days of WW2 because of the wall of sandbags at the right edge of the image.
No. 8821 became BR 62572 in August 1949 and would be withdrawn in July 1958 whilst allocated to March mpd.
