Keikyu-Kamata, Castle Wall in the High-density City

Along with Chofu Station on the Keio Line (see my blog on October 17th, 2012), another bottleneck station has dispelled its negative image. That is Keikyu-Kamata Station on the Keikyu Line, some 10 km south of the city center.

On October 22nd, Keikyu Electric Railway completed the construction of elevated tracks around Keikyu-Kamata Station on the Keikyu-Main and Keikyu-Airport lines (see the top photo). A total of 6km of surface tracks have been elevated.

Before completion of the new tracks, Keikyu-Kamata was a bottleneck station on the timetable, as the Main Line and the Airport Line trains crossed on the surface. But, after the completion, a grade separated crossing has made it possible for the trains to be operated smoothly.

Just like Chofu on the Keio Line, another advantage of the elevated tracks is the elimination of traffic jams at railway crossings. The Keikyu lines crossed the arterial road, Route 15. High concentrations of cars passing the railway crossings had been causing chronic traffic congestion. It has completely disappeared after completion of the construction.

In the meantime, with the completion of the grade separated crossing, Keikyu has changed the timetable on the lines. Express services between Shinagawa, Yokohama and Haneda Airport (Tokyo International Airport) have been expanded drastically. It's good news for airline passengers. The next highlight will be a counterplot by Tokyo Monorail, which is Keikyu's primary competitor for transportation between the city center and Haneda Airport.

New Keikyu-Kamata station, it's a castle wall in the high-density city.
