{{nihongo|'''Keikyu Corporation'''|京浜急行電鉄株式会社|Keihin Kyūkō Dentetsu Kabushiki-gaisha}} ({{tyo|9006}}), also known as {{nihongo4||京浜急行|'''Keihin Kyūkō'''}} or, more recently, {{nihongo4||京急|'''Keikyū'''}}, is a private railroad that connects inner [[Tokyo]] to [[Kawasaki, Kanagawa|Kawasaki]], [[Yokohama]], [[Yokosuka, Kanagawa|Yokosuka]] and other points on the [[Miura Peninsula]] in [[Kanagawa Prefecture]]. It also provides rail access to [[Haneda Airport]] in Tokyo. {{nihongo4||京浜|Keihin}} means the {{nihongo4|Tokyo|東'''京'''}} - {{nihongo4|Yokohama|横'''浜'''}} area. The company's railroad origins date back to 1898, but the current company dates to 1948. The railway pioneered [[Kantō region]]'s first electric train and the nation's third, after [[Hanshin Electric Railway]] and Nagoya Electric Railway ([[Meitetsu]]) with the opening of a short {{Convert|2|km|mi|abbr=on}} long section of what later became the [[Keikyū Daishi Line|Daishi Line]] in January 1899.<ref>{{Cite book|series=Color Books No.778|title=Nippon Densha Hattatsu-shi|trans-title=The History of Development of Electric Trains in Japan|author=Yoshikawa, Fumio|language=ja|year=1989|publisher=Hoikusha|location=Osaka|page=99}}</ref>

== Accidents ==
Since 1997, Keikyu has had five accidents, all of which were on the main line, in the vicinity of Yokosuka and Yokohama.

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. The accident occurred between Keikyu-Taura(In Japanese:京急田浦) and Anjinzuka (In Japanese:安針塚 or 按針塚) stations, with approximately 60 people on board. 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. 500 workers were mobilized as the train service was temporarily suspended between Kanazawa-Hakkei and Horinouchi Stations.<ref>"22 injured as mudslide derails train" The Daily Yomiuri (April 8, 1997).</ref>

On 24 November 2000, at about 5:20 am, the front car of a four-car train derailed after a truck collided with the first car of the train at a railroad crossing, resulting in 3 passengers being slightly injured. The accident occurred in Yokosuka and the approximately 100 commuters on board later walked about 200 m to the nearest station to continue their commute via bus. The driver of the truck reported his foot became stuck between the accelerator and brake pedals, sending him through the crossing bar and into the crossing. Normal operations continued about 4 hours later that morning.<ref>"Kanagawa truck-train collision hurts 3" The Daily Yomiuri (November 25, 2000).</ref>

On 24 September 2012, at about 11:58 pm, the first three cars of an eight-car train derailed after colliding with a mudslide, resulting in injuries to 28 people including the train driver. 7 men and women were seriously injured, including fractures, broken ribs and pelvises. The accident occurred between Oppama and Keikyu Taura stations, between Yokohama and Yokosuka, with approximately 700 passengers on board. Heavy rains caused the mudslide, sweeping away safety nets that had been installed in 1998, the year after a similar mudslide in the area.<ref>Aoki, M. (September 27, 2012). "Keikyu ups injury total from derailment to 28". The Japan Times</ref> An area of soil about 12 meters high and 15 meters wide fell onto the tracks, bringing trees and fencing structures with it. The train was travelling 75&nbsp;km/h before the driver applied the brakes, 30 to 40 meters before the mudslide.<ref>"11 injured in train derailed by landslide". (September 26, 2012). The Daily Yomiuri</ref> Train services were temporarily suspended between Kanazawa-Hakkei and Hemi stations and temporary bus services were provided by the train company until normal operations resumed approximately {{frac|55|1|2}} hours later after the assessment and clean-up process.<ref>Keikyu line resumes operations; company to reconsider sections subject to driving restrictions. (September 28, 2012). The Daily Yomiuri</ref>

On 18 April 2013, at about 4:30 pm, two window panes shattered in the front car of a local commuter train while passing an express train going the opposite direction, resulting in minor cuts to two high school students sitting with their backs to the windows. One window pane was also cracked on the passing train with no injuries. The accident occurred between Taura and Anjinzuka stations, with approximately 30 people in that car at the time of the accident.<ref>Carriage windows shatter as keikyu trains pass. (April 19, 2013). Japan Today. Retrieved from http://www.japantoday.com/category/national/view/carriage-windows-smash-as-keikyu-trains-pass</ref>

On 5 September 2019 a limited express train crashed into a truck in nearby Kanagawa-Shinmachi Station. There were 33 injuries and 1 death (truck driver).<ref>{{cite web
