History

On 28 June 1902, the Keihin Railway opened the 1,435 mm (4 ft 8+1⁄2 in) Anamori Line from Kamata to Anamori Station (穴守駅), located near the present-day site of Tenkūbashi Station. The line was electrified at 600 V DC.[1] In 1904, the line was regauged to 1,372 mm (4 ft 6 in) in conjunction with the Keikyu Main Line, and the entire route was double-tracked by 1910.[1]

The line was constructed primarily to serve visitors to Anamori Inari Shrine, located in front of Anamori Station. To increase ridership, Keihin Railway developed leisure facilities in the surrounding area, including a baseball park, tennis courts, a swimming pool, and an amusement park. In 1931, Haneda Airport opened approximately 500 m (1,600 ft) north of Anamori Station.

The Anamori Line became the primary rail route to Haneda Airport until 1945, when the airport was taken over by the United States Armed Forces. The line was subsequently reduced to single track to accommodate a parallel freight line. On 1 November 1963, it was renamed the Airport Line. Despite this designation, the line was not widely used for airport access due to limited service frequency and the absence of through services to central Tokyo, particularly after the opening of the Tokyo Monorail in 1964, which provided direct service from Hamamatsuchō to the airport terminal.

Rail service to the airport island resumed in April 1993, when the line was extended across the river to a new Haneda Airport Station at the present-day site of Tenkūbashi Station.[1] That year, Haneda Airport underwent significant expansion with the opening of a new terminal, and Keikyu received government approval to serve the facility after the monorail was deemed to have insufficient capacity. On 18 November 1998, the Airport Line was further extended from Tenkūbashi to Haneda Airport Station (now Haneda Airport Terminal 1·2 Station),[2] enabling direct services between the airport and major stations such as Shinagawa and Yokohama.[1] An infill station serving Terminal 3 opened on 21 October 2010.[1]

Future plans

Service levels are expected to increase following the completion of tail tracks at Haneda Airport Terminal 1·2 Station.[3]
