Parsons Marine Steam Turbine Company company. In 1944, Parsons was one of 19 companies which formed the 'Parsons and Marine Engineering Turbine Research and Development Association', usually known as Pametrada. The last ship to use a Parsons propulsion system was launched in 1964. The company was absorbed into C. A. Parsons and Company and survives in the Heaton area of Newcastle as part of Siemens, a German industrial conglomerate. Parsons Marine Steam Turbine Company Parsons Marine Steam Turbine Company was a British engineering company based in Wallsend, North East England, on the River Tyne. The company was founded by Charles Algernon Parsons in 1897 with
Steam turbine locomotive locomotive. However, poor efficiency at slow speeds doomed this turbine, and with diesel-electrics being introduced, no more S2s were built. The locomotive was retired in 1949 and scrapped in May, 1952. The Reid-Ramsey turbine, built by the North British Locomotive Company in 1910, had a 2-B+B-2 (4-4-0+0-4-4) wheel arrangement. Steam was generated in a standard locomotive boiler, with superheater, and passed to a turbine generator. Exhaust steam was condensed and recirculated by small auxiliary turbine pumps. The armatures of the motors were mounted directly on the four driving axles. It was later rebuilt as a direct-drive turbine locomotive as seen
