History

On 28 June 1902, the Keihin Railway opened the 1,435 mm (4 ft 8 ¹⁄₂ in) gauge Anamori Line from Kamata to Anamori Station (穴守駅) (close to the present-day Tenkūbashi Station), electrified at 600 V DC.^[1] In 1904, the line was regauged to 1,372 mm (4 ft 6 in) in conjunction with the regauging of the Keikyu Main Line. The entire line was double-tracked in 1910,^[1] and in 1935, it was returned to 1,435 mm gauge.

In 1945, one track was converted to 1,067 mm (3 ft 6 in) gauge and used by the Allies to haul freight to Kamata. That line was returned to 1,435 mm gauge in 1952, with dual-track operation resuming. The overhead wire voltage was increased to 1,500 V DC in 1947.

On 20 April 1956, the line was extended to a new Haneda Airport Station (present-day Tenkūbashi Station), and from 1 November 1963 the line was renamed the Airport Line.^[1]

From 18 November 1998, the Airport Line was extended from Tenkūbashi to Haneda Airport Station (present-day Haneda Airport Domestic Terminal Station).^[1] Haneda Airport International Terminal Station opened on 21 October 2010.^[1]
