The Kyoto Line was built by in November 1928 as dual track electrified at
600 V DC. The track between Kyoto Station and Horiuchi Station (present-day
Kintetsu-Tambabashi Station) was placed on the site of a removed railway, which had been rerouted and is now called the
JR Nara Line. The railway provided the through services to the lines of Kintetsu (originally, Osaka Electric Tramway) from the beginning. As of September 1961, Kintetsu was the largest shareholder of Nara Electric Railway with 980,000 shares out of the company's 1.9 million shares, while
Keihan Electric Railway owned 710,000 shares. Through a deal between the two major shareholders, the shares owned by Keihan were transferred to Kintetsu in April 1962 and the company was merged into Kintetsu from October 1963. The line voltage was increased to 1,500 V DC in 1969, and in 1988 through services with the Karasuma Line were introduced. ==Stations==
