The number of trains gradually increased after JR's ownership of the Kosei Line, and a through train to Fukui via Tsuruga Station and a train running toward the south from Omi-Shiotsu Station to Nagahama Station and Maibara Station on the Hokuriku Line were established after the electrification.
JRになってから徐々に本数は増え、電車化後は敦賀を越え福井方面へ直通する列車や、近江塩津から長浜・米原へ北陸線を南下する列車も設定された。
