Metropolitan-Vickers andBeyer, Peacock & Co. formed a joint venture company in November 1949 to design and manufacture diesel, electric and gas turbine locomotives. Because Beyer, Peacock's Gorton works was still busy producing steam locomotives, an alternative site for the new locomotives to be built had to be found. A factory at Yarm Road,Stockton-on-Tees, on which Metrovicks had acquired a lease in 1947, was chosen as the location. The factory which had been built in 1946 for the American construction machinery company LeTourneau, was almost brand new, and covered an area of around 95,000 square feet (8,800 m2), later extended to over 125,000 square feet (11,600 m2) by Metrovicks. The works had its own railway siding running from Bowesfield Junction to the north east of the works. Initially the factory was used by Metrovicks for steel fabrication work before locomotive manufacture began in 1949.
The first locomotives built at the works were fourteen electric locomotives for theRede Mineira de Viação railway company ofBrazil. They were 1,072 horsepower (799 kW),Bo-Bo,1,000 mm (3 ft 3+3⁄8 in)metre gauge gauge locomotives. This was followed by another order for ten similar locomotives forRede de Viação Paraná-Santa Catarina, Brazil.
In 1954–55, the works built fortyNew South Wales 46 class electric locomotives forNew South Wales Railways inAustralia, along with the forty-eightWAGR X class diesel electric locomotives built forWestern Australian Government Railways, during 1953–56.
The only locomotives built forBritish Railways at the works, were the twentyBR Class 28 diesel electrics during 1958–59, and the experimental 25 kV AC locomotiveE1000 which was built by converting the gas turbine locomotive18100. Work commenced in January 1958 when 18100 was brought to Bowesfield Works from storage atDukinfield Works. The conversion of 18100 involved the removal of thegas turbine unit, generator and the middle traction motor from each bogie, which changed the locomotive from aCo-Co to anA1A-A1A wheel arrangement. The necessary electrical equipment such as thetransformer,mercury arc rectifiers andpantograph etc. was installed, with the work completed by October 1958.
In addition to building mainline locomotives, the works also constructed twelve Metropolitan-Vickers DBF type,3 ft (914 mm) gauge, battery powered under ground mining locomotives for theNational Coal Board during 1959.
The last locomotives built at the works was a batch of 135,SAR Class 5E1, Series 1 electric, 2,280 horsepower (1,700 kW), 3000V d.c.,Bo-Bo,3 ft 6 in (1,067 mm) gauge locomotives forSouth African Railways and Harbours during 1958–60.
In December 1960, it was announced that the works was facing closure due to a lack of orders, and in February 1961, the Metropolitan-Vickers-Beyer Peacock joint company was placed into voluntary liquidation. The works was closed shortly afterwards and the workforce made redundant.
The factory building was taken over by theVisqueen company, a manufacturer ofpolythene films, which is now part of theBritish Polythene Industries group. The factory closed, and from 2011 the site was taken over by Bellway Homes who developed the site as their Queensgate development which features 2,3, and 4 bedroom homes.
