Ivatt GNR designed C12 4-4-2T No. 4509 is seen here shunting at the un-GNR location of Saffron Walden on 3/8/41. I was delighted to see this shot as it includes a rare sighting of the small engine shed and its associated turtable. There is another odd thing about this image as the trucks that are being manoevered are spaced at regular intervals along the running line although that isn't readily apparent here as the image had to cropped. Renumbering of 4509 to 67367 came with nationalisation and withdrawal was from Grantham mpd in 1958.
