[quote]QUOTE: Originally posted by rdganthracite The turbines used by the C&O (3), the N&W (1), the PRR (1), and the Pre WWII turbines on the UP (2) were steam turbines rather than gas turbines. The difference being that with a steam turbine you have a boiler which creates the steam which turns the turbine. In a gas turbine you burn the fuel directly in the turbine. Just think about what you normally call jet engines, GE used aircraft engines in the gas turbines that they made for the UP. Westinghouse did the same with the Blue Goose demonstrator. Westinghouse did not have any sales of turbines though. UP also built a coal dust fired gas turbine out of an ALCO PA, an ex GN electric, and an idle steam locomotive tender. It worked reasonably well, except that the cinders ate the turbine blades rather quickly. [/quote] In reference to the comment about the UP coal dust fired gas turbine, it was a failure and did not run many trips before it was laid up for good. The article about it said it sounded much like the normal turbine except for the blades breaking and coming through the car body. That is the quote from the men who tested it.
