It runs from Yamashina in Yamashina -ku, Kyoto Prefecture after Ōmi - Shiotsu in Nagahama, Shiga Prefecture. The name of the track means " western sea line ", which refers to the route along the shore of Lake Biwa.
The Kosei Line is used by many workers to be settling to Osaka, Kobe and Kyoto. Since the commuting distances are sometimes very far, but the offer is on the Kosei Line in local, rapid and differentiated Limited Express connections. Many compounds are bound from Yamashina on the Tōkaidō Main Line to Kyoto, where, inter alia, a transition to the Tōkaidō Shinkansen is.
In addition to the compounds of daily offer also used the night train Nihonkai that runs between Osaka and Aomori, the Kosei Line. Furthermore, the Kosei Line is also used for freight.

The Kosei Line is an option for the planned extension of the Hokuriku Shinkansen from Osaka to Kanazawa. In contrast to two other possible Trassierungsvarianten that should be investigated, no conversion of the Kosei Line would be from Cape gauge to standard gauge at the Kosei -line option. Instead, the present experimental Kikan Kahen Densha would be used that would have umspurbare chassis and therefore could change from standard-gauge Shinkansen network to the kapspurige Kosei Line.
