Keikyu Corporation (京浜急行電鉄株式会社, Keihin Kyūkō Dentetsu Kabushiki-gaisha) (TYO: 9006), also known as Keihin Kyūkō (京浜急行) or, more recently, Keikyū (京急), is a private railroad that connects inner Tokyo to Kawasaki, Yokohama, Yokosuka and other points on the Miura Peninsula in Kanagawa Prefecture.

The company changed its English name from Keihin Electric Express Railway Co., Ltd. to Keikyu Corporation on 21 October 2010.

[4] Trains on the Main Line have a maximum operating speed of 120 km/h (75 mph), making it the third fastest private railroad in the Tokyo region after the Keisei Skyliner and the Tsukuba Express.

The Keikyu Main Line runs between south area of Tokyo, Kawasaki, Yokohama, and Yokosuka.

On 7 April 1997, at about 2:47 pm, the first three cars of a four-car train derailed after colliding with a mudslide, resulting in 22 people injured.

Heavy rains caused the mudslide, 7 months after a report by the train company to the Transportation Minister that there was little probability of such an occurrence in that area.

The accident occurred between Oppama and Keikyu Taura stations, between Yokohama and Yokosuka, with approximately 700 passengers on board.
