The Monongahela Railway was a coal-hauling short line railroad in Pennsylvania and West Virginia in the United States. It was jointly controlled originally by the Pennsylvania Railroad, New York Central subsidiary Pittsburgh and Lake Erie Railroad, and the Baltimore and Ohio Railroad, with NYC and PRR later succeeded by Penn Central Transportation. The company operated its own line until it was merged into Conrail on May 1, 1993. The primary connection to both controlling systems was at Brownsville, Pennsylvania - with the south end of the P&LE's Pittsburgh, McKeesport and Youghiogheny Railroad and with the PRR's ex-Brownsville Railway. The PRR also interchanged traffic at Hoover, Pennsylvania, the end of its Coal Lick Run Branch. The B&O Railroad interchanged at Leckrone, Pennsylvania, and Rivesville, West Virginia. At the end of 1970 it operated 193 miles of road on 281 miles of track; that year it reported 446 million ton-miles of revenue freight. History The Monongahela Railroad's headquarters and base of operations was Brownsville, Pennsylvania. "As early as 1883, the Pittsburgh, Virginia & Charleston Railway served Brownsville as evidenced by an old lithograph of the Three Towns showing a diamond stacked locomotive coupled to four passenger cars, ready for a northward move, sitting on the track close to the Snowden House and the United States Post Office. However, the June, 1893, Official Guide (page 324), does not indicate any passenger service to Brownsville off the Redstone Branch." The Monongahela Railroad was a joint venture of the Pennsylvania Railroad (PRR) and the Pittsburgh and Lake Erie Railroad (P&LE), both of which had plans to extend their lines in the area. Each company appointed four of their members to the board of directors, who held their first meeting in January 1901. The newly formed Monongahela Railroad acquired many lines in the area from the PV&C as well as the Southwest Pennsylvania Railway Company, as well as the 19 mile (30 km) right of way from Brownsville to Adah from the PRR, for the sum of $519,696.13. In 1905 the Dunlap Creek branch opened, serving several mines and coke works and also connecting with the Baltimore and Ohio Railroad. The last move on this line was on November 6, 1975; the track was removed and the real estate disposed. In 1909 the Rush Run branch was constructed, and a patch town (Sarah, Pennsylvania) was constructed to house the workers at what was to have been
