During the daytime, aside from regional rapid trains, rapid trains ran through Yamato-Koizumi Station and Koriyama Station (Nara Prefecture) (their destination sign was orange, when in those days, the lettering of these signs was written in red), and daytime trains that ran directly between JR Nanba and Takada and came to stop at every station on the Wakayama Line were also operated as 'rapid trains' rather than 'regional rapid trains.'
また昼間にはこの区間快速とは別に大和小泉駅・郡山駅_(奈良県)通過の快速（種別の色がオレンジ。当時は旧幕の字体であって赤色で表示）や、昼間のJR難波-高田間直通で和歌山線内各駅停車となる列車も「区間快速」ではなく「快速」として走っていた。
