Also in the early 1960s, it became known that United Steel Companies (USC) were to close their wheel and axle works, 'Baker and Bessemer' at Kilnhurst, and discussions regarding this matter between THR and USC revealed that the Yorkshire Engine Company, YEC locomotive business might be disposed of. Rolls-Royce opened negotiations with United Steels which continued throughout 1964 and finally in 1965 Rolls-Royce acquired the stock and goodwill of YEC and all locomotive production at Meadow Hall ceased. Three diesel hydraulic locomotives in stock at YEC, together with a consignment of spare parts were transferred to THR. Rolls-Royce undertook to build any future YEC diesel electric locomotives that might be required. Three Janus locomotives for USC at Scunthorpe plus one smaller locomotive for GEC and a similar powered diesel-electric for Zambia. Rolls-Royce insisted at that time in dealing with any export enquiries direct, a process that did not work and no further YEC design locomotives were built.
