Intermodal passenger transport in the context of "Washington Union Station"

30th Street Station, officially William H. Gray III 30th Street Station, is a major intermodal transit station in Philadelphia, Pennsylvania, United States. The station opened in 1933 as Pennsylvania Station–30th Street, replacing the 1881 Broad Street station as the Pennsylvania Railroad's main station in the city. The station is the third-busiest Amtrak station in the nation with over 4.1 million passengers as of 2023.

30th Street Station is currently metropolitan Philadelphia's main railroad station and a major stop on Amtrak's Northeast and Keystone corridors. The station is also a major commuter rail station served by all SEPTA Regional Rail lines and is the western terminus for NJ Transit's Atlantic City Line. The station is also served by several SEPTA-managed city and suburban buses and by NJ Transit, Amtrak Thruway, and various intercity operators.

South Station is a railroad terminal located at Dewey Square in downtown Boston, Massachusetts. It is the busiest railroad station in Greater Boston and the second-busiest transportation facility. It is New England's second-largest transportation center after Logan International Airport. Along with North Station, it is one of two Boston terminals for the MBTA Commuter Rail system and Amtrak intercity rail service. South Station is a major intermodal transit hub; the South Station Bus Terminal is located above the platforms, and the adjacent subway station is served by the Red Line and Silver Line of the MBTA subway system.

Four terminals were built near downtown Boston in the 19th century to serve railroads running south and west from Boston. South Station was constructed in 1899 to replace these terminals with a union station. The Classical Revival structure was designed by Shepley, Rutan and Coolidge. Passenger rail service declined during the 20th century; the bankrupt railroads sold the station to the Boston Redevelopment Authority (BRA) in 1965. Portions of the station were demolished for redevelopment. Plans to demolish and redevelop the remaining section fell through; it was added to the National Register of Historic Places in 1975 as South Station Headhouse.

Getty Square is the name for downtown Yonkers, New York, centered on the public square. Getty Square is the civic center, central business district, and transit hub of the City of Yonkers. A dense and growing residential area, it is located in southern Westchester County, New York. The square is named after prominent 19th-century merchant Robert Getty.

Hoboken Terminal is a commuter-oriented intermodal passenger station in Hoboken, Hudson County, New Jersey. One of the New York metropolitan area's major transportation hubs, it is served by eight NJ Transit (NJT) commuter rail lines, an NJ Transit event shuttle to Meadowlands Sports Complex, one Metro-North Railroad line, various NJT buses and private bus lines, the Hudson–Bergen Light Rail, the Port Authority Trans-Hudson (PATH) rapid transit system, and NY Waterway-operated ferries.

More than 50,000 people use the terminal daily, making it the tenth-busiest railroad station in North America and the sixth-busiest in the New York area. It is also the second-busiest railroad station in New Jersey, behind only Newark Penn Station, and its third-busiest transportation facility, after Newark Liberty International Airport and Newark Penn Station.

Many major railway stations, bus stations and ferry terminals that are involved in intermodal passenger transport are assigned codes by the International Air Transport Association (IATA), similar to IATA airport codes. Such railway stations, bus stations and ferry terminals are typically used in air-rail alliances or code sharing agreements (commonly known as "Rail Fly") between airlines, rail lines, and ferry lines, but can also be used for buses run directly from airlines (such as the Helsinki Airport - Turku / Tampere buses directly operated by Finnair), particularly in Europe. By assigning stations an IATA code, passengers on trips involving those stations can be ticketed all the way through the journey, including being checked straight through to their final destination, without the bother of having to claim their baggage and check-in again when changing between the surface and air portions of a trip. At other places, passengers have to carry their baggage onto the train, but need no separate train booking process.

These kinds of arrangement can help airlines removing their short-haul flights and reduce their carbon footprint.

Kuala Lumpur Sentral Station (KL Sentral) is a transit-oriented development that houses the main railway station of Kuala Lumpur, the capital of Malaysia. Opened on 16 April 2001, KL Sentral replaced the old Kuala Lumpur railway station as the city's main inter-city railway station. KL Sentral is the largest railway station in Malaysia, and also in Southeast Asia from 2001 to 2021, before Krung Thep Aphiwat Central Terminal in Bangkok, Thailand was completed.

KL Sentral is designed as an intermodal transport hub. All of Kuala Lumpur's passenger rail lines serve KL Sentral except the Ampang line, Sri Petaling line, Shah Alam line and Putrajaya line. Passengers can catch intercity trains serving many locations across Peninsular Malaysia to places such as Johor Bahru, Ipoh and Butterworth, as well as special monthly excursion trains towards Thailand. It was also designed to be a new business and financial hub for Kuala Lumpur.
