Monongahela Railway: Map, Rosters, History

Last revised: September 22, 2026

The Monongahela Railway was a coal railroad with three famous parents and one job. Reporting mark MGA. From Brownsville, Pennsylvania, it ran south along its namesake river into the northern West Virginia seams and back out again, handing hoppers to the Pennsylvania, the Pittsburgh & Lake Erie, and, after 1927, the Baltimore & Ohio. The main line from Brownsville to Fairmont was about 69 miles. With branches it was still a short railroad. At the end of 1970 it operated 193 miles of road. In its last years it was loading on the order of 30 million tons a year, on heavy rail, and it looked like a small Class I.

The Monongahela Railroad was incorporated under Pennsylvania law on December 31, 1900. The first board met in January 1901. Trains of its own were running by 1903. On July 1, 1915, it consolidated with the Buckhannon & Northern and took the name Monongahela Railway. Conrail absorbed it on May 1, 1993.

Brownsville, 1900

The Pennsylvania reached West Brownsville on May 15, 1881, over the Pittsburgh, Virginia & Charleston, and folded that company in on April 1, 1905. The Pittsburgh & Lake Erie came down the other side of the argument in 1890, by way of the McKeesport & Belle Vernon, to a point near Brownsville. The two owners were rivals everywhere else. South of Brownsville they agreed that one jointly owned coal road was cheaper than two.

Each parent named four directors. The new Monongahela Railroad took over the rail the Pennsylvania already had in the Brownsville area, including a 19-mile right of way from Brownsville toward Adah that the Pennsylvania sold for $519,696.13, and pieces of the South-West Pennsylvania Railway. Construction from Brownsville Junction to Adah Run ran through 1901–1903. Brownsville became the headquarters, the shop town, and the place the hoppers were made up for Pittsburgh and the Ohio mills. In 1910 the company put a ten-stall roundhouse in Bridgeport, now South Brownsville. That yard stayed the principal terminal for the life of the railroad.

The Monongahela Connecting, the U.S. Steel switching road inside Pittsburgh, was a different company and a different map.

To Fairmont

The Dunlap Creek branch opened in 1905, mines and coke ovens on a line that also reached the Baltimore & Ohio. The last move on it was November 6, 1975. Rush Run, 4.2 miles built in 1908–1909, is the branch that almost wasn’t. A patch town, Sarah, was laid out for a mine whose coal turned out to belong to someone else. Four trains ran on the branch, the ones that brought the ballast, and then the line and the town were taken up.

The push that made the railroad was the state-line extension. Between 1910 and 1914 the company built south from Martin to the Pennsylvania–West Virginia line, with a river crossing and two large creek bridges, to meet the Buckhannon & Northern. That West Virginia road had been incorporated February 7, 1902, aimed first at Buckhannon and Fairmont and then, under George Gould and the Wabash, at a longer scheme that was never finished. What opened, under Pittsburgh & Lake Erie influence, was about 30 miles from the state line to a Baltimore & Ohio connection at Rivesville Junction. The Paw Paw branch left Rivesville for a mine at Loveridge.

Articles of consolidation dated November 24, 1914, were filed in Pennsylvania on July 1, 1915, and in West Virginia on July 10. The Monongahela Railroad and the Buckhannon & Northern became the Monongahela Railway. The main line those two companies made, Brownsville to Fairmont, was about 69 miles. A short Prickett Creek cutoff around Fairmont, built by the Baltimore & Ohio to get coal trains out of a crowded terminal, was later folded into that main.

Branches and new mines

In 1927 the Baltimore & Ohio bought one-third of the stock, one-sixth from each of the original owners. It was already in the neighborhood. It held a quarter of the Buckhannon & Northern, a third of the Chartiers Southern, and all of the Indian Creek & Northern, a three-mile spur from Lowsville, West Virginia, to Federal Nos. 3 and 4 at Arnettsville. That spur came up between 1960 and 1963.

The west bank was the Chartiers Southern country. The Pennsylvania, Monongahela & Southern, organized in 1902, reached Crucible on December 15, 1913. Service to the town began November 1, 1919. The Ten Mile Run branch opened to Waynesburg on January 1, 1930. Emerald Mine, near Waynesburg, was still a shipper long after the Monongahela name was gone.

Scotts Run was a failed interurban that became a coal branch. The Morgantown & Wheeling left the river at Randall, just north of Morgantown, and reached Brave, Pennsylvania, in August 1918, well short of Wheeling. The Scotts Run Railway was organized in May 1923 to take it over. The first four miles served nearly three dozen mines. The railroad was also a 4 percent hill railroad with sharp curves. The last train to Brave ran on February 12, 1967, and the branch came up in the 1970s.

The replacement was new railroad, which by the 1960s almost nobody was building. The Waynesburg Southern, organized in September 1966 in the Pennsylvania’s interest, opened in June 1968: about 27 miles from the Ten Mile Run line to a connection with Scotts Run at Blacksville, plus the six-mile Miracle Run spur. Grades were gentle. The White Cottage Tunnel, about halfway, is 1,415 feet. The mines were Blacksville No. 1, Blacksville No. 2, Federal No. 2, and Emerald. In 1984 the 15-mile Manor Branch opened to the Bailey Mine. Coal loadings that had been a few million tons in the 1970s were reported near 30 million tons a year by the early 1990s.

Passenger trains

Passengers were a sideline from the start. Service began with the railroad in 1903 and reached Fairmont with the 1915 consolidation. There were seventeen stops that mattered, including Brownsville Union Station, a two-story depot opened in January 1929 and shared with the Pennsylvania and the Pittsburgh & Lake Erie. The 1920s were the best years. A gasoline railcar arrived from the Pittsburgh & Lake Erie in 1940 and was sold after a short career. The last passenger train, Fairmont to Brownsville, ended on October 21, 1950.

Three owners, then two

The Pennsylvania and the Pittsburgh & Lake Erie each held half until the Baltimore & Ohio’s 1927 purchase. After the war the parents had their own troubles, and the Monongahela showed it: deferred maintenance, a steam fleet that lasted until May 26, 1954, and a diesel roster that began with Baldwin S-12s on November 25, 1952, because Eddystone would still build a plain switcher and the railroad needed twenty-seven of them. Secondhand New York Central sharknose RF-16s arrived in 1967, the last of that model still at work. Five new GP38s came in 1969. Nine secondhand Pittsburgh & Lake Erie GP7s followed in the mid-1970s. The Super 7s of 1989–1990, former Western Pacific U23Bs rebuilt with Dash-8 electronics, were the last purchase. Paul Reistrup, then the Monongahela’s president, gave the rebuild its name.

Penn Central inherited the Pennsylvania and New York Central shares. Conrail inherited Penn Central’s. The Baltimore & Ohio share became a CSX share. The Pittsburgh & Lake Erie sold out. By the late 1980s the owners were Conrail and CSX. CSX sold its one-third interest in 1990. Conrail had complete control in 1991 and merged the company on May 1, 1993. The last decade had 132-pound welded rail, a maintained right-of-way, and computer-assisted dispatching on a railroad of fewer than 175 route-miles.

What remains

In the 1999 breakup of Conrail, Norfolk Southern took the former Monongahela as the MGA Mine District. CSX kept the right to serve shippers on the line. Both railroads still run coal over the old Brownsville–Fairmont road and the mine branches that survived. In 2012 Norfolk Southern painted ES44AC 8025 in Monongahela colors for its thirtieth-anniversary heritage set.

The locomotives are on the other two pages. There is no George Drury chapter for this railroad. The steam roster is the all-time class list from David Gratz and Terry Arbogast, with the USRA Mikados and the Baldwin L-2s checked against the builder records. The diesel roster is every diesel-electric the Monongahela numbered, with serials and, where the builder used one, the order number.
