The Black Rock Tunnel is an active rail road tunnel of the old Reading Railroad. The 1835 tunnel was the third rail tunnel constructed in the United States, and is the third oldest still in use. [1] The tunnel is also notable as being the first for which shafts were sunk during construction. [2] The tunnel is cut through a hill in Phoenixville, Pennsylvania, United States. The tunnel and line are now owned by Norfolk Southern as part of its Harrisburg Line.
The Black Rock Tunnel was constructed between 1835 and 1837 and opened in 1838. W. Hasell Wilson was the resident engineer in charge. [2] The tunnel was originally 1,932 feet (589 m) long, 19 feet (5.8 m) wide, and 17 feet (5.2 m) high. [3] The tunnel passes 122 feet (37 m) below the top of the hill. [1] A then-unique feature of the tunnel's construction was the sinking of six, 7-foot (2.1 m) diameter shafts, tangent to the tunnel cross section. These shafts were spaced at 100-foot (30 m) intervals to correct errors in the tunnel alignment. [2] Construction of the tunnel cost an estimated $178,992. [4]
Noted local miner, geologist and palaentologist Charles M. Wheatley examined the rock excavated from the tunnel and identified many previously unknown fossilized species, some of which now bear his name. [5]
In 1858 and 1859 the Black Rock and Flat Rock Tunnels were widened to accommodate the wider rolling stock from the Lebanon Valley Branch. The spacing between the tracks was increased from 4 feet (1.2 m) to 6 feet (1.8 m). The widening of the tunnel was the first project to employ electric detonation of multiple explosive charges. [6]
The northern end of the tunnel is high on a steep bank of the Schuylkill River so the rail line makes a dramatic transition from tunnel to bridge. The ends of the Black Rock Tunnel are located at 40°08′51″N75°31′06″W / 40.14750°N 75.51833°W and 40°08′39″N75°30′46.5″W / 40.14417°N 75.512917°W .
Phoenixville is a borough in Chester County, Pennsylvania. It is located 28 miles (45 km) northwest of Philadelphia at the junction of French Creek and the Schuylkill River. It is in the Philadelphia metropolitan area. The population is 18,616 as of the 2020 Census. As noted by Forbes, Phoenixville is a former beaten-down mill town with a recent downtown revitalization plan that led to 10 craft breweries, a distillery, and winery tasting rooms.
The Schuylkill River is a river running northwest to southeast in eastern Pennsylvania. The river was improved by navigations into the Schuylkill Canal, and several of its tributaries drain major parts of Pennsylvania's Coal Region. It flows for 135 miles (217 km) from Pottsville to Philadelphia, where it joins the Delaware River as one of its largest tributaries.
Horseshoe Curve is a three-track railroad curve on Norfolk Southern Railway's Pittsburgh Line in Blair County, Pennsylvania. The curve is about 2,375 feet (700 m) long and 1,300 feet (400 m) in diameter. Completed in 1854 by the Pennsylvania Railroad as a way to reduce the westbound grade to the summit of the Allegheny Mountains, it replaced the time-consuming Allegheny Portage Railroad, the only other route across the mountains for large vehicles. The Curve was later owned and used by three Pennsylvania Railroad successors, Penn Central, Conrail, and Norfolk Southern.
The Union Canal was a towpath canal that existed in southeastern Pennsylvania in the United States during the 19th century. First proposed in 1690 to connect Philadelphia with the Susquehanna River, it ran approximately 82 mi from Middletown on the Susquehanna below Harrisburg to Reading on the Schuylkill River.
The Hoosac Tunnel is a 4.75-mile (7.64 km) active railroad tunnel in western Massachusetts that passes through the Hoosac Range, an extension of Vermont's Green Mountains. It runs in a straight line from its east portal, along the Deerfield River in the town of Florida, to its west portal in the city of North Adams.
The Cincinnati, Lebanon and Northern Railway (CL&N) was a local passenger and freight-carrying railroad in the southwestern part of the U.S. state of Ohio, connecting Cincinnati to Dayton via Lebanon. It was built in the late 19th century to give the town of Lebanon and Warren County better transportation facilities. The railroad was locally known as the "Highland Route", since it followed the ridge between the Little and Great Miami rivers, and was the only line not affected by floods such as the Great Dayton Flood of 1913.
Schuylkill River Passenger Rail is a proposed passenger train service along the Schuylkill River between Philadelphia and Reading, Pennsylvania, with intermediate stops in Norristown, King of Prussia, Phoenixville, and Pottstown.
The Schuylkill Canal, or Schuylkill Navigation, was a system of interconnected canals and slack-water pools along the Schuylkill River in the U.S. state of Pennsylvania, built as a commercial waterway in the early 19th-century. Chartered in 1815, the navigation opened in 1825 to provide transportation and water power. At the time, the river was the least expensive and most efficient method of transporting bulk cargo, and the eastern seaboard cities of the U.S. were experiencing an energy crisis due to deforestation. It fostered the mining of anthracite coal as the major source of industry between Pottsville and eastern markets. Along the tow-paths, mules pulled barges of coal from Port Carbon through the water gaps to Pottsville; locally to the port and markets of Philadelphia; and some then by ship or through additional New Jersey waterways, to New York City markets.
Transportation in Lancaster County, Pennsylvania has a long and variegated history. An early-settled part of the United States, and lying on the route between Philadelphia and Harrisburg, it has been the site of early experiments in canals, railroads, and highways. Before all these, at least ten Native American paths crossed parts of the county, many connecting with the Susquehannock village of Conestoga.
Mont Clare is a village in Upper Providence Township, Montgomery County, Pennsylvania, United States. The village is located on the left bank of the Schuylkill River, opposite Phoenixville and Chester County. Mont Clare is at the site of the former Jacobs' ford. Mont Clare hosts the only functional lock and one of only two remaining watered stretches of the Schuylkill Canal. Mont Clare was the birthplace of the infamous outlaw Sundance Kid.
The Harrisburg Line is a rail line owned and operated by the Norfolk Southern Railway (NS) in the U.S. state of Pennsylvania. The line runs from Philadelphia west to Harrisburg.
The Schuylkill Branch was a rail line owned and operated by the former Pennsylvania Railroad (PRR) in the U.S. state of Pennsylvania. The line ran from the Philadelphia to Harrisburg Main Line at 52nd Street in Philadelphia north via Norristown, Reading, and Pottsville to Delano Junction. From Delano Junction, the PRR had trackage rights over the Lehigh Valley Railroad's Hazleton Branch and Tomhicken Branch to Tomhicken, where the PRR's Catawissa Branch began. In conjunction with the Catawissa Branch, Nescopeck Branch, and Wilkes-Barre Branch, the Schuylkill Branch gave the PRR a direct line from Philadelphia to Wilkes-Barre.
The Main Line of the Pennsylvania Railroad was a rail line in the Commonwealth of Pennsylvania, connecting Philadelphia with Pittsburgh via Harrisburg. The rail line was split into two rail lines, and now all of its right-of-way is a cross-state corridor, composed of Amtrak's Philadelphia to Harrisburg Main Line and the Norfolk Southern Railway's Pittsburgh Line.
The Pennsylvania Canal was a complex system of transportation infrastructure improvements including canals, dams, locks, tow paths, aqueducts, and viaducts. The Canal and Works were constructed and assembled over several decades beginning in 1824, the year of the first enabling act and budget items. It should be understood the first use of any railway in North America was the year 1826, so the newspapers and the Pennsylvania Assembly of 1824 applied the term then to the proposed rights of way mainly for the canals of the Main Line of Public Works to be built across the southern part of Pennsylvania.
The Phoenixville Tunnel, originally called the Fairview Tunnel, was part of the Pennsylvania Schuylkill Valley Railroad in Phoenixville, Pennsylvania.
The Flat Rock Tunnel is an active railroad tunnel located on Norfolk Southern's Harrisburg Line near Manayunk, Pennsylvania, United States. The tunnel was built by the Reading Railroad for its line along the Schuylkill River.
The Catawissa Railroad was a railroad that operated in Pennsylvania between 1860 and 1953. For most of its lifespan it was leased by the Reading Company, and was subsequently merged into the Reading.
The Pickering Valley Railroad was a short line railroad in Chester County, Pennsylvania. It ran from Phoenixville to Byers, near Eagle, in Upper Uwchlan Township, a distance of approximately 11 miles (18 km), over which distance it gained 316 feet (96 m) in elevation. Operated as a unit of the Reading Railroad, the Pickering Valley was not a great success; passenger service was discontinued in 1934, and most of the line was abandoned in 1948. The remainder of the line was closed in the 1980s; little remains today.
The Lehigh Line is a railroad line in central New Jersey, Northeastern Pennsylvania, and the Lehigh Valley region of eastern Pennsylvania. It is owned and operated by the Norfolk Southern Railway. The line runs west from the vicinity of the Port of New York and New Jersey via Conrail's Lehigh Line to the Susquehanna River valley at the south end of the Wyoming Valley Coal Region. Administratively, it is part of Norfolk Southern's Keystone Division and is part of the Crescent Corridor. As of 2021 the line is freight-only, although there are perennial proposals to restore passenger service over all or part of the line.
