The 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 Gloucester Railway Carriage and Wagon Company, each with two 230 hp British United Traction - Albion engines.Ian Allan ABC of British Railways locomotives, winter 1962/3 edition, page 289 The class was built specifically for parcels, fitted out with parcel racks and bike storage at each end, and did not feature any passenger accommodation. The last members of the class were withdrawn in 1990 and broken up the following year, and none were preserved.
