On a bright and sunny Friday 26th January 2024, a very smart English Electric Class 37 No. 37901 'Mirrlees Pioneer' (re-engined with a Mirrlees MB275T in 1986) runs through Ely and onto the Down Goods Line to run round Barrier Vehicles 6340 and 6344 on 5M57, the 15.14 Ely Papworth Sidings to Derby Railway Technical Centre. Vehicle 6340, nearest the camera, was formerly Mark 1 Brake Composite Corridor (BCK) No. 21251, built in 1962 at Swindon Works and has an impressive 62 years of service behind it! Photo: Tony Field.
