[quote]QUOTE: Originally posted by M636C There was a proposal for an EMD Gas Turbine, but this was quite different to the GE Turbines used by UP. This was a "gas generator" turbine which was to use French 'Pescara' free piston engines (double ended diesel engines with no crankshaft but two pistons that fired alternately, producing exhaust gas which loses its energy in a direct drive turbine coupled through driveshafts and gearboxes like diesel hydraulic locomotives)[/quote] That sounds very much like the free piston/turbine engine that Westinghouse was pursuing in the late '40s and early '50s. Westinghouse had ads in most of the mags of the time. They even took over Baldwin in 1950 so they would have a major erecting facility for the orders they were sure would be coming for the turbine and for the opposed piston diesel engine that Westinghouse had been developing and transferred to Baldwin. Baldwin was about to come out with a new Vee type engine that would have been competitive with the 567 and 251 but Westinghouse shelved it in favor of the exotic possibilities. The free piston engine that Westinghouse was developing was to be a larger version of the free piston diesel compressors that some of the more modern U Boats used very successfully during the war. Unfortunately for Baldwin neither power plant panned out, and since they were using 1930's design diesel engines they went out of business rather quickly
