Baldwin DS-4-4-1000

The Baldwin DS-4-4-1000 covers two models of four-axle, 1,000 horsepower diesel-electric switcher locomotives built by Baldwin Locomotive Works between 1946 and 1951. The first 56 locomotives used an eight-cylinder normally aspirated prime mover, and from 1948 a second model used a six-cylinder turbocharged engine. Both replaced the VO-1000 in Baldwin's catalog and were in turn replaced by the S-12 in 1951. Preserved examples include Santa Fe 2260 at the Museum of the American Railroad in Frisco, Texas, Canadian Pacific 7069 at the Toronto Railway Museum, and Reading 702 at the Reading Railroad Heritage Museum in Hamburg, Pennsylvania.
