Pittsburgh Locomotive and Car Works was organized in Allegheny City, Pennsylvania in August 1865. The shop opened in the fall of 1866, and the first locomotive was finished in April 1867. By 1872 the shop had doubled its size, and by the following year, the 326th engine was completed. Orders fell off for several years until the company selected D.A. Wightman as the new superintendent. Wightman upgraded the plant with new tools, improved methods of production and a comprehensive building program. In 1901 American Locomotive Company formed, and the Pittsburgh Company was among several independents merged into the new corporation.
