Intercity rail in the context of "Mass transit system"

Public transport (also known as public transportation, public transit, mass transit, or simply transit) are forms of transport available to the general public. It typically uses a fixed schedule, route, and charges a fixed fare. There is no rigid definition of which kinds of transport are included, and air travel is often not thought of when discussing public transport—dictionaries use wording like "buses, trains, etc." Examples of public transport include city buses, trolleybuses, trams (or light rail), rapid transit (metro/subway/underground, etc.) and passenger trains and ferries. Public transport between cities is dominated by airlines, coaches, and intercity rail. High-speed rail networks are being developed in many parts of the world.

Most public transport systems run along fixed routes with set embarkation/disembarkation points to a prearranged timetable, with the most frequent services running to a headway (e.g., "every 15 minutes" as opposed to being scheduled for a specific time of the day). However, most public transport trips include other modes of travel, such as passengers walking or catching bus services to access train stations. Share taxis offer on-demand services in many parts of the world, which may compete with fixed public transport lines, or complement them, by bringing passengers to interchanges. Paratransit is sometimes used in areas of low demand and for people who need a door-to-door service.

The National Railroad Passenger Corporation, doing business as Amtrak (/ˈæmtræk/; reporting marks AMTK, AMTZ), is the national passenger railroad company of the United States. It operates intercity rail service in every contiguous U.S. state except for Wyoming and South Dakota as well as in three Canadian provinces. Amtrak is a portmanteau of the words America and track.

Founded in 1971 as a quasi-public corporation to operate many U.S. passenger rail routes, Amtrak receives a combination of state and federal subsidies but is managed as a for-profit organization. The company's headquarters is located one block west of Union Station in Washington, D.C. Amtrak is headed by a Board of Directors, two of whom are the secretary of transportation and chief executive officer (CEO) of Amtrak, while the other eight members are nominated to serve a term of five years.

The Keystone Corridor is a 349-mile (562 km) railroad corridor between Philadelphia and Pittsburgh, Pennsylvania, that consists of two rail lines: Amtrak and SEPTA's Philadelphia-to-Harrisburg main line, which hosts SEPTA's Paoli/Thorndale Line commuter rail service, and Amtrak's Keystone Service and Pennsylvanian inter-city trains; and the Norfolk Southern Pittsburgh Line. The corridor was originally the Main Line of the Pennsylvania Railroad.

Amtrak runs two intercity rail services along the Keystone Corridor: the Harrisburg-to-New York City Keystone Service and the Pittsburgh-to-New York City Pennsylvanian. SEPTA operates daily Paoli/Thorndale commuter rail service between Philadelphia and Thorndale on the Philadelphia-to-Harrisburg main line. The towns along this stretch form a socio-cultural region called the "Philadelphia Main Line".

Luz Station (Portuguese: Estação da Luz, IPA: [(i)staˈsɐ̃w dɐ ˈlus]) is a commuter rail and intercity rail station in the Bom Retiro district of São Paulo, Brazil, serving RFFSA, the intercity rail network of Brazil, CPTM Line 7-Ruby, Line 11-Coral and Line 13–Jade (Airport-Express). It has subway connections to São Paulo Metro Line 1-Blue and ViaQuatro Line 4-Yellow via its underground metro station of the same name.

It is currently located in Bairro da Luz and was built between 1895 and 1901, designed by the British architect Charles Henry Driver for the São Paulo Railway, a company based in London that was responsible for building the first railway line in the state of São Paulo, connecting the port of Santos to the city of Jundiaí.
