How it started
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 4.2 mi (6.8 km) Rush Run branch was constructed, and a patch town (Sarah, Pennsylvania) was constructed to house the workers at what was to have been a coal mine. It was later determined that the coal did not belong to the mine developer, and the line was abandoned, the town was scrapped. Only four trains ever ran on this line, those carrying the ballast to complete the track.
In 1910 the federal government condemned the low-clearance covered bridge in Bridgeport (now South Brownsville), and the Monongahela Railroad bought the bridge company and removed the bridge. In the same year they installed a 10-stall roundhouse in Bridgeport. This was to be the main yard for the railroad throughout its history.
