Northeast Regional in the context of "Inter-city rail"

The Acela (/əˈsɛlə/ ə-SEL-ə; originally the Acela Express until September 2019) is Amtrak's flagship passenger train service along the Northeast Corridor (NEC) in the Northeastern United States between Washington, D.C., and Boston via 13 intermediate stops, including Baltimore, New York City and Philadelphia. Acela trains are the fastest in the Americas, reaching 150–160 miles per hour (240–260 km/h), qualifying as high-speed rail, but only for approximately 40 miles (64 km) of the 457-mile (735 km) route.

In fiscal year 2024, Acela carried more than 3.2 million passengers, second only to the slower and less expensive Northeast Regional, which had over 10.8 million passengers. Ridership was down from the pre-COVID-19 pandemic high of 3,557,455 passengers in 2019. Its 2024 revenue of $531 million was around 21% of Amtrak's total.

Newark Liberty International Airport (IATA: EWR, ICAO: KEWR, FAA LID: EWR) is a major international airport serving the New York metropolitan area. The airport straddles the boundary between the cities of Newark in Essex County and Elizabeth in Union County, in the U.S. state of New Jersey. Located approximately 4.5 miles (7.2 km) south of downtown Newark and 9 miles (14 km) west-southwest of Manhattan, it is a major gateway to destinations in Europe, South America, Asia, and Oceania. It is jointly owned by the two cities, and the airport itself is leased to its operator, the Port Authority of New York and New Jersey. It is the second-busiest airport in the New York airport system behind John F. Kennedy International Airport and ahead of LaGuardia Airport.

The airport is near the Newark Airport Interchange, the junction between both Interstate 95 and Interstate 78 (both of which are components of the New Jersey Turnpike), and U.S. Routes 1 and 9, which has junctions with U.S. Route 22, Route 81, and Route 21. AirTrain Newark connects the terminals with the Newark Liberty International Airport Railway Station. The station is served by NJ Transit's Northeast Corridor Line and North Jersey Coast Line. Amtrak's Northeast Regional and Keystone Service routes also make stops at the station.

Newark Liberty International Airport Station (also known as Newark Airport Rail Station and Newark RaiLink station, and often announced simply as Newark Airport) is a railroad hub on the Northeast Corridor (NEC) in Newark, New Jersey. The station provides access to Newark Liberty International Airport (EWR) via the AirTrain Newark monorail which connects the station to the airport's terminals and parking areas. The station is served by New Jersey Transit's (NJT) Northeast Corridor Line and North Jersey Coast Line and Amtrak's Northeast Regional and Keystone Service trains.

The station, located in the Dayton neighborhood of the city, is accessible only by train. A project to expand the station to include direct pedestrian access is under construction.
