Between the anti-tank blocks on the W side of the railway (SMR 20028/MCC5149) and the hairpins on the E side is a distance of perhaps 20 yards which would have been bridged by anti-tank obstacles. Across the line itself, moveable obstacles would have maintained the integrity of the defences although it is not known at the present time what form these took. However, an aerial photograph taken in 1949 shows two parallel rows of small white dots smaller than cubes bridging the gap between the railway line and the position of the hairpins (SMR 20030/MCC5151). There were perhaps 9 or 10 dots in each row, many close together. It is not known what these were, perhaps pimples although these were usually in a staggered formation or the concrete footings of upright lengths of railway line.<1>
