Because of their unique appearance, the JNR/JR Suburban Train Series 419 and JNR/JR Suburban Train Series 715, which were called 'bread trains,' and JNR/JR Suburban Trains Series 457, which were converted from the rapid train, were used at Omi-Imazu Station and stations to the north from 1991, but they disappeared from regular operation on the Kosei Line after Tsuruga Station was DC-electrified due to the revision.
また、特異な姿から食パン電車とも呼ばれる国鉄419系・715系電車や、急行から転用の国鉄457系電車が近江今津以北で1991年以降使用されていたが、敦賀直流化の改正以降湖西線に定期運用で姿を現すことはなくなった。
