Steam turbine steam jacks. In 1672 an impulse steam turbine driven car was designed by Ferdinand Verbiest. A more modern version of this car was produced some time in the late 18th century by an unknown German mechanic. In 1775 at Soho James Watt designed a reaction turbine that was put to work there. In 1827 the Frenchmen Real and Pichon patented and constructed a compound impulse turbine. The modern steam turbine was invented in 1884 by Sir Charles Parsons, whose first model was connected to a dynamo that generated 7.5 kW (10 hp) of electricity. The invention of Parsons' steam turbine
Steam turbine locomotive turbine failed after eleven years in heavy service. The Turbomotive was converted to piston drive in 1952, renamed "Princess Anne" and shortly after entering service was withdrawn following the deadly Harrow and Wealdstone railway accident in 1952. Another locomotive was built by Beyer-Peacock, using the Ljungström turbine by Fredrik Ljungström. Like one of Ljungström's early designs, the driving wheels were under the tender. Performance was disappointing, however, partly because of poor heating of the boiler. Another unit was rebuilt by the North British Locomotive Company. In its first incarnation (described below) it had an electrical transmission. Only a few tests
