MARC Train in the context of "Washington Union Station"

The Northeast Corridor (NEC) is an electrified railroad line in the Northeast megalopolis of the United States. Owned primarily by Amtrak, it runs from Boston in the north to Washington, D.C., in the south, with major stops in Providence, New Haven, Stamford, New York City, Newark, Trenton, Philadelphia, Wilmington, and Baltimore. The NEC is roughly paralleled by Interstate 95 for most of its length. Carrying more than 2,200 trains a day, it is the busiest passenger rail line in the United States by ridership and service frequency.

The corridor is used by many Amtrak trains, including the high-speed Acela (formerly Acela Express), intercity trains, and several long-distance trains. Most of the corridor also has frequent commuter rail service, operated by the MBTA (Keolis), CT Rail, Metro-North Railroad, Long Island Rail Road, New Jersey Transit, SEPTA, and MARC. While large through freights have not run on the NEC since the early 1980s, some sections still carry smaller local freights operated by CSX, Norfolk Southern, CSAO, Providence and Worcester, New York and Atlantic, and Canadian Pacific. CSX and NS partly own their routes.

Lucketts is an unincorporated historic hamlet in Loudoun County, Virginia, United States, along U.S. Route 15, north of Leesburg. It was originally known as "Black Swamp" due to the large number of black oak trees growing in the area at the time of its settlement. From the late 18th century until the mid-19th century, it was known as "Goresville" after the name of prominent local landowner, Thomas Gore. The name was finally changed to "Lucketts" in 1865. The town's Lucketts School is listed on the National Register of Historic Places.

Lucketts is approximately 7 miles (11 km) north of Leesburg and 18 miles (29 km) south of Frederick, Maryland. The Potomac River is between Lucketts and Frederick, approximately 4 miles (6 km) north on Route 15. Also, Washington Dulles Airport (IAD) is located 23 miles (37 km) to the south, with some of the airport's major approach and departure paths directly above. The MARC commuter train makes frequent stops on the Maryland side in Point of Rocks. Train whistles of the freight trains at night and dawn are frequently heard throughout Lucketts.
