York, Philadelphia and Norfolk Railroad (NYP&N), that connected southern markets with the north. Despite no longer being an executive with PRR, he was elected to the PRR's board of directors and was recalled in 1899 to serve as president. Cassatt more than doubled the PRR's total assets during his term, from $276 million to $594 million, while Track and equipment investment increased by almost 150 percent. The route from New York through Philadelphia, Harrisburg and Altoona to Pittsburgh was made double-tracked throughout; to Washington, D.C., four-tracked—Pennsy's "Broad Way." Many other lines were double-tracked; almost every part of the system was improved. New freight cutoffs avoided stations; grade crossings were eliminated, flyovers were built to streamline common paths through junctions, terminals were redesigned, and much more. Cassatt initiated the Pennsy's program of electrification which led to the road being the United States' most electrified system. Cassatt was succeeded as Pennsylvania Railroad president by James McCrea. Civil engineer In the Spring of 1861, Cassatt had been hired as part of the Engineer Corps of the Pennsylvania Railroad, again as a rodman where he worked on the Connecting Railway. It is unknown how Cassatt managed to avoid the Pennsylvania militia draft during the Union mobilization in this period but in 1864, Cassatt was transferred to Renovo, Pennsylvania, as a resident engineer to work on the middle division of the Philadelphia and Erie railroad. In 1866, Cassatt became superintendent of motive power and machinery for the Oil Creek and Allegheny River Railway, recently reorganized in 1864 as the Warren and Franklin Railroad which was growing rapidly due to the discovery of oil in the region and coal mining. In 1867, Cassatt was appointed as superintendent of motive power and machinery for the Pennsylvania railroad in Altoona with a salary of $3,000 per year ($=) when a trainman made less than $10 a week ($=). Sometime during Cassatt's tenure as superintendent, he married Lois Buchanan, daughter of the Rev. Edward Y. Buchanan and Ann Eliza Foster. Lois Buchanan was a niece of James Buchanan, 15th President of the United States, and through her mother, a niece of songwriter Stephen Foster. The couple had two sons and two daughters. In 1872, Cassatt was elected as a member to the American Philosophical Society.
