Context paragraphs:
Luray Norfolk and Western Passenger Station: The Luray Norfolk and Western Passenger Station is a historic train station located in Luray, Virginia, United States.  The Shenandoah Valley Railroad reached Luray in 1881 and constructed a station near where the present station is located.  Shortly after the Norfolk and Western Railway absorbed the Shenandoah Valley Railroad in 1890, plans arose to construct a new station in Luray.  This station, which still stands, was constructed in 1906 and was designed by the railroad's Chief Engineer, Charles S. Churchill.  The structure was partially destroyed by fire in 1908 when it was struck by lightning; however, it was soon thereafter reconstructed according to the original design.  The station is a one-story brick structure featuring a hip roof.  The building was converted to freight use around 1960 and was sold to the town of Luray by the Norfolk and Western's successor, the Norfolk Southern Railway, in 1999.

Conococheague Mountain Tunnel: The Conococheague Mountain Tunnel was a proposed railroad tunnel in Perry County, Pennsylvania.  It was originally planned as part of the Path Valley Railroad, with the intent to link the Newport and Shermans Valley Railroad with the East Broad Top Railroad and the Tuscarora Valley Railroad further west.  Only about 100 feet of either end of the planned 2600 foot tunnel was completed in 1894.

Lehigh and Mahanoy Railroad: The Lehigh and Mahanoy Railroad, originally the Quakake Railroad (pronounced quake-ache), was an independently financed railroad planned and built at almost the same time as the Lehigh Valley Railroad (LVRR), when in part, some of its backers were also of the backers (and perhaps officers) of the Lehigh Valley Railroad.  The railroad is mentioned as part of the engineering report following the survey of 1846 by Robert H. Sayre, at the time chief engineer of the Lehigh Coal & Navigation Company, where the branch is "described as part of the overall scheme to connect New York Harbor via the Central Railroad of New Jersey to the frontiers via Lake Erie and the Susquehanna River valley.  The official incorporated name on the report is the Delaware, Lehigh, Schuylkill, & Susquehanna Railroad Co. where the Schuylkill name is the Quakake Creek climb out of the Lehigh Valley and drop down into Delano Junction which has a descent path to Tamaqua, Pennsylvania in the Little Schuylkill River basin.  Accordingly, the Quakake Railroad would become part of the Mahanoy Branch of the Lehigh Valley Railroad in northeastern to north-central Pennsylvania.  The Catawissa region was an important source of iron ores and developed into an Anthracite pig iron smelting center, as did Catasauqua, Pennsylvania also on the line of the Lehigh Valley.

Shenandoah Valley Railroad (1867–90): Shenandoah Valley Railroad was a line completed on June 19, 1882, extending down the Shenandoah Valley from Hagerstown, Maryland through the West Virginia panhandle into Virginia to reach Roanoke, Virginia and to connect with the Norfolk and Western Railway (N&W).  The development of this railroad had considerable backing from the Pennsylvania Railroad.  In September 1890 it went into bankruptcy and was reorganized as the Shenandoah Valley Railway.  In December 1890, it became part of N&W.  Today the tracks are a major artery of the Norfolk Southern system.

Shenandoah Valley Railroad (short-line): The Shenandoah Valley Railroad (reporting mark SV) is a shortline railroad operating 20.2 miles of track between Staunton and Pleasant Valley, Virginia.  The railroad interchanges with CSX and Buckingham Branch in Staunton and Norfolk Southern in Pleasant Valley.  The railroad was purchased from Norfolk Southern in 1993 and is currently operated by the Durbin and Greenbrier Valley Railroad.

Belvidere Delaware Railroad: The Belvidere Delaware Railroad (Bel Del, 1851–1871) was a railroad running along the eastern shore of the Delaware River from Trenton, New Jersey north via Phillipsburg, New Jersey to the small village of Manunka Chunk, New Jersey.  It became an important feeder line for the Lehigh Valley Railroad's join to the Central Railroad of New Jersey, which was constructed into Phillipsburg, NJ at about the same time.  This connected Philadelphia and Trenton, NJ at one end of the shortline railroad to the rapidly growing lower Wyoming Valley region, and via the Morris Canal or the CNJ, a slow or fast connection to New York City ferries crossing New York Harbor from Jersey City, NJ.  In 1871 the CNJ leased various railroads in Pennsylvania, most from the Lehigh Coal & Navigation Company allowing the CNJ to penetrate to the upper Wyoming Valley, over some stretches, competing directly with the Lehigh Valley Railroad and with the Lehigh Canal and the trunk road connection of the Belvidere Delaware Railroad to New York became less profitable since Philadelphia connected more easily to Northeastern Pennsylvania thereafter without needing a double-crossing of the Delaware River; a general revenue decline ensued, leading to the Pennsylvania Railroad acquiring the rights, where it served as part of the Pennsylvania Railroad (PRR) system, carrying mainly anthracite coal and iron ore from northeastern Pennsylvania to population centers along the coast.

Cumberland Valley Railroad: The Cumberland Valley Railroad (reporting mark CVRR) was an early railroad in Pennsylvania, United States, originally chartered in 1831 to connect with Pennsylvania's Main Line of Public Works.  Freight and passenger service in the Cumberland Valley in south central Pennsylvania from near Harrisburg to Chambersburg began in 1837, with service later extended to Hagerstown, Maryland and then extending into the Shenandoah Valley to Winchester, Virginia.  It employed up to 1,800 workers.

Canadian Pacific Railway No. 1246: Canadian Pacific Railway No. 1246 was one of three 1200-series Canadian Pacific Railway locomotives in the Steamtown, USA collection.  Like CP 1293 and CP 1278, this locomotive was one the operational engines at Steamtown.  When Steamtown left its Bellows Falls, Vermont location in the fall of 1983, the engine led the "farewell to Vermont" excursions.  There were two such 100 mi excursions "through a landscape of covered bridges, rushing streams and scenic countryside".  The train had the capacity of 800–1000 passengers.  Built in 1946, CPR 1246 is a 4-6-2 type, class G5c locomotive.  After operating in Steamtown in Scranton between 1984–1986, it was determined that 1246 was inadequate for service as it was "too light for the heavy grades and sharp curves of the Steamtown line".  The National Park Service sold it to the|Connecticut Valley Railroad]], in 1988.  Note The locomotive was never owned by the Valley Railroad of Essex.Ct.  The Railroad Museum of New England,changed their name from The Connecticut Valley Railroad sometime after they moved to Thonaston, Ct.  The engine was moved to the Connecticut Valley Railroad This locomotive was on static display from 1996–2008, at the Valley Railroad in Essex, Connecticut.  In 2008, it was moved to the Naugatuck Railroad which is operated by the Railroad Museum of New England, Thomaston, Connecticut.

Pennsylvania Railroad: The Pennsylvania Railroad (reporting mark PRR) (or Pennsylvania Railroad Company and also known the "Pennsy") was an American Class I railroad that was established in 1846 and was headquartered in Philadelphia, Pennsylvania.  It was called the Pennsylvania Railroad because it was established in the state of Pennsylvania.

Durbin and Greenbrier Valley Railroad: The Durbin and Greenbrier Valley Railroad (reporting mark DGVR) is a heritage and freight railroad in the U.S. states of Virginia and West Virginia.  It operates the West Virginia State Rail Authority-owned Durbin Railroad and West Virginia Central Railroad (reporting mark WVC) , as well as the Shenandoah Valley Railroad in Virginia.  Beginning in 2015, DGVR began operating the historic geared steam-powered Cass Scenic Railroad, which was previously operated by the West Virginia Division of Natural Resources as part of Cass Scenic Railroad State Park.
