Commission) proposed consolidating the region's rail operations, including a new Washington Union Station (approved 1903, completed 1908) and a New Long Railroad Bridge (completed 1904). In accordance with the plan, the Pennsylvania Railroad (PRR), Baltimore and Ohio Railroad, Southern Railway, Chesapeake and Ohio Railway, Atlantic Coast Line Railroad, and Seaboard Air Line Railway formed the Richmond-Washington Company to manage traffic. This holding company controlled the Richmond, Fredericksburg and Potomac Railroad (RF&P), the new Alexandria Union Station, which opened in 1905, and the new switching yard—Potomac Yard—which opened on October 15, 1906. The booming "Pot Yard" attracted thousands of workers, who largely settled in the areas of Del Ray and St. Elmo. These subdivisions incorporated as the town of Potomac in 1908, but were annexed by the City of Alexandria in 1930. Potomac Yard in its heyday was one of the busiest railyards in the Eastern United States, processing thousands of cars daily. The PRR extended its railway electrification program to Potomac Yard in 1935, marking its southernmost point. The Penn Central segment of the famous Tropicana Juice Train operated from here. The site reached capacity in 1937. After the corporate mergers of the former separate railroad companies that used the yard to interchange freight cars, the need for Potomac Yard greatly diminished. It was determined by the RF&P that the land was worth more than the need for yard switching. The PRR's old catenary was dismantled in the 1980s. The facility was identified as a toxic waste site in 1987. The RF&P finally decommissioned it in 1989. Plans for rehabilitation and redevelopment of the land have been a source of intense debate since then. Redevelopment At decommissioning, decades of industrial use had left the site contaminated with heavy metals and hydrocarbons, including diesel fuel. It was immediately declared a Superfund site. In 1995 the Environmental Protection Agency (EPA) approved RF&P's study and cleanup plan, and cleanup was declared completed by 1998. Various commercial and community interest groups came into conflict over the future of the brownfield land. The City of Alexandria rejected the original mixed-use plan in 1992. Jack Kent Cooke, owner of the then Washington Redskins, unsuccessfully pushed for the construction of a new football stadium on the site. Seventy of the 400 acres (1.6 km²) of the site were approved for retail use in 1995; the Potomac Yard Center, a strip mall anchored by big box stores, was
