PITTSBURGH LOCOMOTIVE WORKS RECORDS, 1874-1910
#164
(1.5 cubic feet: 2 DB, 2 F/O)
by: E.S. Etuk & Robert S. Harding, September 1985
History
Pittsburgh Locomotive and Car Works was founded by Andrew Carnegie and T.N. Miller in 1865.
Like most other railway companies, Pittsburgh Locomotive and Car Works was involved in
designing and building light locomotive engines. Its first locomotive was finished in April, 1867,
two years after the Civil War.
An energetic new superintendent, Daniel A. Wightman of Allegheny, Allegheny County, joined the
company soon after its founding. The date of his employment with the company is unknown, but
Wightman's sketches of locomotives appear about 1874. In 1893, Wightman applied to the
Commissioner of Patents for patent rights over his invention of an improvement in compound
engines.
Wightman was the company's Superintendent and General Manager between 1895 and 1900. By
the following year, 1901, the company had built a total of 2,400 locomotives. That same year,
Pittsburgh Locomotive merged with a new corporation, the American Locomotive Company. The
American Locomotive eventually closed the Pittsburgh plant after March, 1919.
Pittsburgh Locomotive Works was one of the first to produce really huge locomotives under Daniel
A. Wightman. Many of these engines were sold to other Railway Companies throughout the United
States.
Scope and Content
This collection consists of business correspondence 1895-1901 of the company, including
correspondence of the General Manager, D.A. Wightman; personal papers of Mr. Daniel A.
Wightman including a sketch book, 1874-76; Specifications for locomotives and tenders; price lists;
locomotive cost estimates; tests; hauling capacities of locomotives; and conditions of
apprenticeship. In addition, there are also as 311 blueprints of the company's designs or drawings
for various sizes of locomotives.
Provenance
Transferred from the Division of Transportation July 3, 1985.
