History

The line was opened on 21 January 1899 by the Daishi Electric Railway (大師電気鉄道), as a standard gauge line electrified at 600 V DC, between Kawasaki Station (later renamed Rokugōbashi Station (六郷橋駅), which closed in 1949) and Daishi Station (later renamed Kawasaki-Daishi Station).^[3] The company was renamed Keihin Electric Railway (京浜電気鉄道) on 25 April 1899.^[3] The line was double-tracked over its entire length from 29 November the same year,^[3] and extended from Rokugōbashi Station to the present-day Keikyu Kawasaki Station on 1 September 1902.^[3]

The line was extended to Sakuramoto in 1945, and the overhead line voltage was raised from the original 600 V DC to 1,500 V DC on 16 March 1951 except for the Shiohama to Sakuramoto section, which was transferred to the Kawasaki Streetcar Co. and operated as a tramway.^[3]

Originally, the line was built to transport the visitors of Kawasaki Daishi buddhist temple. But later, factory workers increased, as the east side of the temple became an industrial zone.^{[citation needed]}
