37688 Great Rocks arrives at Long Marston on 7 September 2020 with the 5Z20 07:08 Crewe to Long Marston ECS. I was surprised to get this, as I had photographed it earlier at Aldington, and the walk back to the car, and the minor roads en-route, should have insured that it arrived at Long Marston before I did. However, as I was driving up to the bridge, it was slowly approaching, so a quick sprint from the car secured this bonus picture.
