Black Fork Grade (Western Maryland): History and Operations

Published: September 26, 2026

Black Fork Grade was the operating problem the Western Maryland never solved, only staffed. It is the climb through Blackwater Canyon between Hendricks and Thomas, West Virginia, on the old West Virginia Central main line that became the Thomas Subdivision. A loaded coal train took a locomotive for about every ten cars. An H-9 Consolidation, the railroad’s best 2-8-0, could handle about ten loads and no more.

A railroad that had to drop into the canyon

The West Virginia Central reached the North Fork of the Blackwater at Thomas in the mid-1880s, on its way from the Potomac toward the timber and coal south of Tucker County. The next town that mattered was Hendricks, where Blackwater River meets Dry Fork to form the Black Fork of the Cheat. The ridge between them is short on a map and brutal on a profile. In 1888 Henry Gassaway Davis sent the railroad into the canyon anyway. Engineers took the only line that would stay in the drainage: down the Blackwater from Thomas, past the falls country, to Hendricks.

A marker erected at Hendricks in 2017 states the result in one sentence. The grade drops 1,236 feet in about 10 miles, with pitches of 3.75 percent. Fairfax, a small place just east of Thomas, was the summit the crews used as a milepost. From there the railroad still had work to do, south of Parsons and over Haddix into Elkins, but the canyon was the part everyone meant by Black Fork Grade. The Western Maryland bought the West Virginia Central in 1905 and ran the same profile, under the same name, for eighty years.

Ten loads, and then another engine

Eastbound coal was the train that made the reputation. Loads came off the mines south of Elkins, were marshaled in the Elkins yard, and started north for Thomas, Cumberland, and tidewater. South of Parsons the railroad was merely steep. At Hendricks it became a helper district. In steam years the extra engines cut into the train there: some on the head end, some mid-train, some on the rear. The rule of thumb, repeated by the men who worked it and by the railroad’s own 1952 film Fast Freight Rolling, was one locomotive for every ten loads. A 50-car coal train was a five-engine train. A longer one could carry eight or ten, which is the number the film used. The 1972 account in Trains put the same arithmetic on the H-9: that class could take about ten loads up the hill, and no more.

The helpers stayed on through the canyon and came off at Fairfax, about four miles east of Thomas, once the worst of the climb was behind the caboose. Thomas had the turntable and the shop where those engines turned and waited for the next eastbound. Westbound empties were easier and still not easy. The grade was steep enough that a train of empty hoppers had to be handled, not just allowed to roll.

Published figures for the steepest pitch do not agree, and they should not be averaged into a false decimal. The Hendricks marker says 3.75 percent. Trains in November 1972 says 3.85 percent. The 1952 film says 3.8 percent and calls the whole struggle 17 miles, a number that reaches beyond the canyon itself toward the Elkins end of the subdivision. What the crews agreed on was the method. Short cuts of loads. Engines everywhere in the train. A speed, once the diesels came, of about 12 miles an hour for the ten miles into Thomas.

Thomas, then Elkins

The steam engine for this work was the Consolidation. H-9s, the heavy Baldwin 2-8-0s of 1921–23, were the ones a 1972 writer measured against the grade. H-7s and H-8s, the Elkins-branch engines with smaller drivers, worked the same canyon when the H-9s were elsewhere. Shays, whose regular WM job was the Chaffee Branch and its 9 percent mine spurs, also appeared on Black Fork when the railroad needed a geared engine on a piece of railroad that ordinary rod power was punishing. The class list is the steam roster.

Diesels moved the helper terminal. By 1972 the extra units were added at Elkins, not Hendricks, and they were cut out at Thomas, because the worst of the climb was over once the train was out of the canyon. Four EMD units on the head end, in the cab ride Trains published that November, took 22 loads and 13 empties, 2,225 tons, up the grade without a mid-train helper, and the writer noted that a mid-train cut of as many as six units was the more ordinary diesel practice. The speed settled near 12 miles an hour. The same four-axle EMDs and Alcos that fit every other Elkins curve fit this one. The serials are the diesel roster.

Thomas kept the scar of the old arrangement. The turntable pit was still visible when that 1972 train went by. The men and the engines had already moved to the roundhouse at Elkins.

A canyon the railroad left to a trail

Coal on the Thomas Subdivision thinned after the deep mines played out in the 1950s. The grade stayed in service because what coal remained still had to get out, and because the Elkins Division still reached Cumberland this way. Floods in November 1985 tore up the Thomas Subdivision, Hendricks and Parsons among the damaged towns. CSX, which had inherited the line through the Baltimore & Ohio, did not repair it. The track between Elkins and the north came up over the next few years.

The canyon grade is a trail now, the Blackwater Canyon Railroad Grade Trail, about 12.2 miles between Thomas and Hendricks, on the old right of way. The culverts over Tub Run, Big Run, and Flatrock Run are still the railroad’s. The helper operation is the thing a photograph can still show, and the Price picture at the top of this page is that operation: a train out of Elkins, in the canyon, with more engines than a railroad of this length would own if the hill were any kinder.
