In the portion of Wadayama northward, trains are often delayed because of the Bantan Line's limited express, which runs straight into this line, and special train service in the tourism season, including the time required for tourists to get on and off.
和田山以北では播但線の特急も乗り入れている関係や、観光シーズンになると臨時列車の運行や乗降に時間を取られ、遅延が発生することが多い。
