The British Rail Class 28 (Metropolitan-Vickers Type 2) diesel locomotives, or 'Metrovicks' as they were popularly known, were built as part of the British Railways 1955 Modernisation Plan. The locomotives had a Co-Bo wheel arrangement (a 6-wheel bogie at one end, a 4-wheel bogie at the other) – unique in British Railways practice though not uncommon in other countries, notably Japan. This made maintenance more complicated. The maximum tractive effort of 50,000 lbf (220 kN) was unusually high for a Type 2 locomotive but, as there were five (not four) driving axles, the risk of wheelslip was minimal.
