Tokyo Monorail is a monorail system connecting Haneda Airport to Hamamatsucho Station. The trains operate along an elevated line that follows the coast of Tokyo Bay.
The line opened in 1964 to coincide with the 1964 Summer Olympics. Built by Hitachi Monorail, the first cars were made in Japan from the German ALWEG design (also used in the Seattle and the original Disneyland Monorail), and were replaced by newer models in 1969, 1977, 1982, and 1989.
Originally, the monorail only served Hamamatsucho and the airport. The first station added in between was the Ooi Race Track in 1965, followed by Seibijou in 1967.
When the monorail began operation, the passenger terminal at Haneda Airport was located on the west side of the airfield, south of Seibijou, and this was the southern terminus of the monorail. Upon the opening of the new passenger terminal (now Terminal 1) in 1993, the monorail was extended to a new platform, and the former passenger terminal was razed to make room for an extension of Runway B. The now-unused monorail tunnel leading to the old station was leased from the Transport Ministry and therefore had to be restored to its original state prior to its handover. Although the rails were removed from the tunnel and its entrance walled off, the tunnel remains otherwise intact today below the extension of Runway B.
A1-station, 0.9km extension to Haneda's new Terminal 2 opened on December 1, 2004, and the opening of a passing loop at Showajima allowed starting express services from March 18, 2007.
Currently, the Tokyo Monorail serves ten stations and handles about 300,000 passengers on weekdays, operating from 5:30 AM to midnight with over 500 trains.
