Gas turbine-electric locomotives

In April of 1950, Baldwin and Westinghouse completed an experimental 4,000 hp (3,000 kW) gas turbine locomotive, numbered 4000, known as the "Blue Goose", with a B-B-B-B wheel arrangement. The locomotive used two 2,000 hp (1,500 kW) turbine engines fueled by Bunker C fuel oil, was equipped for passenger train heating with a steam generator that utilized the waste exhaust heat of the right hand turbine, and was geared for 100 miles per hour (160 km/h). While it was demonstrated successfully in both freight and passenger service on the PRR, MKT, and CNW, no production orders followed, and it was scrapped in 1953.

General Electric

In 1952, General Electric successfully introduced Gas Turbine Electric Locomotives for the Union Pacific Railroad.
