The is a commuter rail line in Osaka-Kobe-Kyoto Metropolitan Area, operated by West Japan Railway Company (JR West). The line was completed in 1974 by the former Japanese National Railways (JNR) to provide faster access from the Kansai region to the Hokuriku region. It originates at Yamashina Station in Yamashina-ku, Kyoto and ends at Ōmi-Shiotsu Station in Nagahama, Shiga.
Its name means "the line to the west of the lake," indicating that it approximately parallels the western shore of Biwako. Trains continue from Omi-Shiotsu Station to Tsuruga Station on the Hokuriku Main Line Yamashina to Kyoto Station on the Tōkaidō Main Line for convenient transfer to lines serving the Kansai as well as the Tōkaidō Shinkansen.
In addition to local, Rapid and Special Rapid services, limited express trains such as the Thunderbird, as well as freight trains are frequently operated on the line. Only few of limited express trains stop at Katata or Omi-Imazu and others skip all stations on the line.
A direct Tsuruga – Kyoto line was included in the 1922 Railway Construction Act.
In the meantime, the Kojaku Railway Co. opened a line from Hamaotsu on the Keihan Ishiyama Sakamoto Line 51km (32miles) to Omi-Imazu between 1923 and 1929. Between 1947 and 1965 there was a connection between Zeze on the Tokaido Main Line and Hamaotsu, allowing direct connection to the Tokaido Line.
The line was purchased by JNR and closed in 1969 so the Kosei line could be constructed over parts of the alignment, with the entire new line opening in 1974 as a dual track electrified line with CTC signalling.
The section from Nagahara to Ōmi-Shiotsu, originally electrified with 20 kV AC, was re-electrified to 1,500 V DC on September 24, 2006 enabling DC-only EMUs used in Osaka-Kyoto region to operate, and the Special Rapid through train service from JR Kyoto Line (Tokaido Main Line) was extended beyond Ōmi-Shiotsu to Tsuruga on the Hokuriku Main Line.
Legends:
Local (普通) trains stop at all stations, but they do not operate through services to the JR Kyoto Line.
Rapid (快速) trains operate only in the mornings, which heads south to the JR Kyoto Line. 2 services are operated every weekday morning and 1 service is operated every weekend morning.[1]
Special Rapid (新快速) trains operate one train per hour for both directions, throughout daytime.
