Flat Rock Tunnel
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. Construction of the tunnel started in 1836 and it opened in 1840. In 1858-9 the Flat Rock and Black Rock Tunnels were widened to accommodate the wider rolling stock from the Lebanon Valley Branch. The spacing between the tracks was increased from to . The widening of the tunnel was the first project to employ electric detonation of multiple explosive charges.

Railroad Tunnels In Pennsylvania
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lebanon Valley Railroad
The Lebanon Valley Railroad was a railway company in the United States. It constructed the Lebanon Valley Branch between the cities of Harrisburg and Reading, both in the American state of Pennsylvania. The line opened on 18 January 1858. The company and its line were acquired by the Philadelphia and Reading Railroad, a predecessor of the Reading Company, on 20 March 1858, which put them in direct competition with the Pennsylvania Railroad for the Philadelphia to Harrisburg route. The line now belongs to Norfolk Southern Railway and is part of its Harrisburg Line running between Harrisburg and Philadelphia. Passenger service The line was the basis until the 1960s for passenger trains between Harrisburg and Jersey City, yet bypassing Philadelphia, most famously, the 'Queen of the Valley.'

Black Rock Tunnel
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. The tunnel is also notable as being the first for which shafts were sunk during construction. 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. The tunnel was originally long, wide, and high. The tunnel passes below the top of the hill. A then-unique feature of the tunnel's construction was the sinking of six, diameter shafts, tangent to the tunnel cross section. These shafts were spaced at intervals to correct errors in the tunnel alignment. Construction of the tunnel cost an estimated $178,992, equal to $ today. Noted local mi ...
