Within the New York City metropolitan area, the airport system—which includes John F. Kennedy International Airport, LaGuardia Airport, Newark Liberty International Airport (located in New Jersey), Stewart Airport and a few smaller facilities—is one of the largest in the world. The Port of New York and New Jersey, which includes the waterways around New York City and its metropolitan area, is one of the busiest seaports in the United States. There are also three commuter rail systems, the PATH rapid transit system to New Jersey, and various ferries between Manhattan and New Jersey. Numerous separate bus systems also operate to Westchester County, Nassau County, and New Jersey. For private vehicles, a system of expressways and parkways connects New York City with its suburbs.
All the trains are computer-controlled and have no driver: a passenger service agent (PSA) on each train is responsible for patrolling the train, checking tickets, making announcements, and controlling the doors. PSAs can also take control of the train in case of computer failure or emergency. Operation and maintenance of the DLR has been carried out by a private franchise since 1997. The current franchise, due to expire in April 2013, belongs to Serco Docklands Ltd, a company jointly formed by Serco and the former DLR management team.
Since opening on 31 August 1987, the system has been extended and upgraded many times to increase the extent of its coverage and increase capacity with new branches being constructed to take the network to Bank in the City of London, London City Airport, Lewisham and Woolwich Arsenal.

Continuation of the West Cross Route northwards under the roundabout was cancelled leaving two short unused stubs for the slip roads that would have been provided for traffic joining or leaving the northern section.
