British Rail Class 128

British Rail Class 128 was a class of diesel multiple unit, built for British Rail. Introduced in 1959, ten of the class were built by British United Traction, each with two 230 hp Leyland engines. The class was built specifically for parcels, and did not feature any passenger accommodation; fitted out with parcel racks and bike storages at each end. The last members of the class were withdrawn in 1991, and none were preserved.
