[ca. 1834-1962]

The Baldwin Locomotive Works of Philadelphia, founded in 1832, had built more steam locomotives than any other institution in the world by the time construction was phased out in the early 1950s. Late in the 1890s, in conjunction with Westinghouse Electrical Manufacturing Company, Baldwin built small electric locomotives for mining and industrial use. By the mid-1920s, the company started experimenting with "oil" and diesel engines, and by 1939, was producing diesel electric locomotives. In the early 1950s, Baldwin merged with the Lima-Hamilton Company and the Austin-Western Dump Car Company and became the Baldwin-Lima-Hamilton Company, which continued until 1972.

The collection consists primarily of the engineering drawings for the locomotives produced, as well as various related indexes, registers, order books and specification books. The indexing system is incomplete and complicated and some gaps exist in the collection. The drawings are semi-processed at this time. For an explanation of how drawing searches can and cannot be done within our collection, detailed searching instructions are available. *** Please note: These are not searches that you can do yourself on our website. We have no online indexes or databases or digitized images of Baldwin records available over the internet. The instructions merely explain what sorts of searches staff can do for you, or the types of searches you can do if you visit the State Archives yourself or acquire copies of our records.

If we do not hold the records you are looking for, you may wish to consult a descriptive list of other institutions possessing Baldwin records.
