History
The line opened on 15 April 1910, when the section from Temmabashi to Gojō (the present Kiyomizu-Gojō) was placed in service as a double-tracked electric railway. Opening had been scheduled for 1 April but was put back fifteen days after a transformer fire at the Moriguchi substation, and rolling-stock failures on the first day drew harsh newspaper notices, prompting the company to halve fares for three days. The Osaka end had originally been planned to start at Kōraibashi but had to be moved to Temmabashi under pressure from the City of Osaka, and reaching the city centre remained a long-held ambition. The line was developed rapidly in its early years: Japan's first express electric train began running on 15 May 1914, and on 1 April 1915 the railway introduced Japan's first three-aspect colour-light automatic block signals. On 27 October 1915 the line was extended from Gojō to Sanjō, completing the through route between Osaka and Kyoto.
Reaching deeper into central Osaka took half a century: the underground extension from Temmabashi to Yodoyabashi finally opened on 16 April 1963, establishing the present Osaka terminus. Across the 1960s to 1980s the line was progressively grade-separated and quadruple-tracked. The Temmabashi–Gamo Signal Box section was quadruple-tracked and elevated in 1970, and the Doi–Neyagawa Signal Box quadruple-track elevation was completed in 1982. The 12.5 km quadruple-tracked stretch between Temmabashi and the Neyagawa Signal Box is the longest quadruple-track section among the major private railways of the Kansai region; running different train classes on the inner and outer pairs of tracks allows a dense timetable.
On 4 December 1983 the maximum speed was lifted from 105 km/h to 110 km/h. In Kyoto, the street-level section from Tōfukuji to Sanjō was replaced by a tunnel in 1987, and on 5 October 1989 through-services were extended to the current northern terminus, Demachiyanagi, over the connecting Keihan Ōtō Line, which functions as an effective extension of the Main Line. Several stations were subsequently elevated: Hirakatashi in 1993, Neyagawashi in 1999 and Yodo in 2011. On 19 October 2008 the Keihan Nakanoshima Line opened with through-running from the Main Line, and the same day Gojō and Shijō stations were renamed Kiyomizu-Gojō and Gion-Shijō.
Today the Main Line carries commuter, school and tourist traffic between Osaka and Kyoto. From Sanjō, trains continue onto the Ōtō Line to Demachiyanagi under a unified timetable, and some services run through onto the Nakanoshima Line from Temmabashi. As of March 2025 the line operates a range of services including the all-reserved Liner, the Rapid Limited Express "Rakuraku", Limited Express, Rapid Express, Express, Sub-express, Semi-express and Local trains; extra-fare reserved-seat "Premium Car" accommodation was introduced on 8000-series limited-express trains on 20 August 2017. The Tōfukuji–Sanjō section, long classified as a tramway under the Tramways Act, was reclassified as a railway under the Railway Business Act on 20 December 2013.
The line has a history of accidents, and of flooding tied to the rivers it follows. In 1917 a fire at the Fukakusa depot destroyed 19 vehicles, and the "Taishō great flood" that autumn breached embankments and cut services north of Hirakata Higashiguchi. A collision at the Gamo Signal Box on 3 August 1966, in which an express ran into the rear of a local and injured 51 people, was caused by the express driver missing a red signal and led the company to adopt automatic train stop (ATS) — the first installation on a Kansai private railway. Grade-separation work continues: construction to elevate the remaining at-grade section between Neyagawashi and Hirakatashi began in September 2022, aiming to eliminate 21 level crossings.
