The
Baldwin Locomotive Works was an American builder of
railroad locomotives. It was originally located in
Philadelphia, and later moved to nearby
Eddystone, Pennsylvania. Although the company was very successful as the largest producer of
steam locomotives, its transition to the production of
diesels was far less so. Later, when the early demand for diesel locomotives to replace steam tapered off, Baldwin could not compete in the marketplace. It stopped producing locomotives in 1956 and went out of business in 1972, having produced over 70,000 locomotives, the vast majority powered by steam.
