There was little difference in time between express and local trains in the section from Korien Station to the north, until the timetable revision was made in June 2000, because the local train was not passed by the express train that came up from behind (although, the local train made a stop at Hirakatashi Station and Fukakusa Station in order to let it pass).
香里園以北での急行と普通の格差があまりないために2000年6月のダイヤ改正までは香里園から先は後続の急行に追い抜かれることはなかった（ただし枚方市と深草で特急の通過待ちを行っていた）。
