The 'Beilhack' ZZA Snowplough dates back to 1982, when BR required additional snowploughs on the network. A novel solution was found using redundant bogies from withdrawn Class 40 and 45 locomotives, which were fitted with a plough blade manufactured by Beilhack, and weight added. A total of 10 were built at Stratford and Ashford up to 1990 latterly using Class 45 bogies. They have carried several liveries including BR yellow, Railtrack, and they are still in use today with Network Rail.
