BALDWIN DS 4-4-1000 (BS10a) switcher diesel locomotive



The Baldwin DS-4-4-1000 followed its predecessor model the VO-1000 in 1946 originally using the company's 608NA prime mover. Aside from the updated prime mover the model was virtually identical to the VO1000 with all internal components outsourced to Westinghouse and continued to carry a length of 48 feet, 10 inches. The only noticeable difference was the DS-4-4-1000's increased starting tractive effort of 72,000 pounds. This first version of the model was built through January of 1951 and sold rather poorly as only 56 were ever built. The second version used the company's somewhat more reliable 606SC prime mover produced the same 1,000 horsepower while also offering turbocharging. In just 11 months (from January to November 1951) Baldwin was able to sell some 446 DS-4-4-1000s to several Class Is (like the Union Pacific, Chicago & North Western, Reading, Seaboard, Frisco, B&O, and others), smaller railroads, and industries. Once again, the company's best customer proved to be the Pennsylvania Railroad which bought 136 examples.
