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.
