Due to the capacity of the track allocated to express trains, during the morning rush there are some trains that run on the outbound track along the entire line (three section express trains that start at Moriguchishi Station from 8:00 to 9:00 in the morning, heading for Yodoyabashi Station).
急行線の容量の関係上、朝ラッシュ時には全線外側線を走行する列車がある（守口市を朝8時台に発車する淀屋橋行き区間急行3本）。
