In the case of travel between Yamashina Station and Omi-Shiotsu Station using a standard ticket, an exception of a specific route section is applied, where a fare based on operating kilometers via the Kosei Line also covers that via Maibara Station; however, a specific route section isn't applied to a commuter ticket and consequently passengers can't use commuter tickets via the Kosei Line (which is cheaper) for travel via Maibara Station.
山科～近江塩津間をまたぐ場合、普通乗車券では湖西線経由の営業キロによる運賃で米原経由にも乗車できる経路特定区間の特例があるが、定期券の場合は経路特定区間が適用されず運賃が米原経由より割安な湖西線経由の定期券では米原経由で利用できない。
