About This Trail

The Sligo Spur is a nine mile branch of the Redbank Valley Trail in Clarion County. It leaves the main trail at Lawsonham, at mile 6 on Redbank Creek, and climbs north along Wildcat Run past Rimersburg to Walker Farm Road, a mile south of Sligo borough. This is the hilly cousin of the main trail. The old railroad grade climbs steadily through woods and farm country, with the high points near the Route 861 crossing at Rimersburg and again near Sligo. The surface is crushed limestone the whole way. Rimersburg's business district sits about a mile off the trail by Mill Alley Road, and the Lawsonham end has parking and a portable toilet but no other services.

RailTrailWx TIPS

Sligo Spur

Your comfort. Prognosticated.

  • Northbound from Lawsonham is the uphill direction: about 350 feet of net climb to Walker Farm Road, with the grade reaching about 2 percent in sustained stretches and 3 percent in spots.
  • The trail is well shaded for most of its length, with about a quarter of it in deep woods, so afternoons stay cooler than in the open farm country around Rimersburg,
  • For most of the way the grade hugs the wall of the Wildcat Run valley, and the slope above faces east. Expect morning sun on the trail and shade by mid afternoon.
  • The corridor runs close to north and south. A south wind is a tailwind on the climb toward Sligo and a headwind coming back down; a west wind is mostly blocked by the valley wall.
  • Expect fog in the mornings after calm, clear nights, especially during fall.
  • The lower couple miles of Sligo Spur are quite scenic, so tap the brakes on your fast descent and enjoy the trail.
  • Starting from Sligo, you can reach Brookville, East Brady, Upper Hillville, or Leechburg entirely by rail trail. Eventually, when the Kiski Flyover is complete, you'll be able to reach Butler and points farther south along the Allegheny River.

Trivia

  • Wildcat Furnace, a charcoal iron furnace on Wildcat Run about a mile from Rimersburg, was built in 1843 by Lawson and Flick and abandoned in 1863, and its ruined stack still stood beside the Sligo Branch Railroad in the 1880s.
  • The Sligo furnace of 1845 shipped its iron by boat down the Clarion River to Callensburg before the railroad reached town.
  • The Sligo Branch Coal Company opened its works just east of Rimersburg in 1874 and shipped its first coal in 1875, mining the Freeport upper coal bed.
  • In its early years the Sligo Branch hauled pig iron, tan bark, hoop poles, iron ore, timber, coal, and livestock out of Sligo.
  • Lawsonham takes its name from David Lawson, a surveyor and land agent who named his home there soon after settling.
  • A sawmill stood at Lawsonham for many years until it was taken down to make room for the Low Grade railroad.
  • Mills and 16 coal mines are reported to have once lined the Sligo Spur, and the trail association is still gathering information to pin down where they stood.

History

Iron came before the rails on Wildcat Run. Lawson and Flick built Wildcat Furnace on the run about a mile from Rimersburg in 1843. Two years later a second charcoal furnace went up at Sligo. Sligo shipped its iron by boat down the Clarion River to Callensburg. Wildcat Furnace closed in 1863. The Allegheny Valley Rail Road graded its Low Grade Division along Redbank Creek in 1872 and finished it in March 1873. A branch from that line at Lawsonham up Wildcat Run to Rimersburg and Sligo followed in 1873, built to move lumber and coal out of Clarion County. The Sligo Branch Coal Company opened its mine east of Rimersburg in 1874 and shipped its first coal the next year. The branch carried pig iron, tan bark, hoop poles, iron ore, timber, coal, and stock. The Pennsylvania Railroad bought the Allegheny Valley in 1900. Service on the Sligo Branch ended before the main line did. The last train on the Redbank Valley corridor ran on November 5, 2007, pulling up its own rails as it went. The Allegheny Valley Land Trust bought the corridor on June 25, 2010, and the Redbank Valley Trail Association began building the trail that August. Volunteers surfaced the full nine-mile Sligo Spur with crushed limestone, finishing in August 2019, with parking improvements at the Route 861 trailhead in Rimersburg.
