In the passing stations (except for Ogotoonsen Station and Makino Station), signal equipment, in which classification by the shape of turnout is available in both directions of inbound and outbound lines, was installed (block sections are provided on a double track but there is one block section on a single track).
おごと温泉を除く待避可能駅とマキノには分岐器形状による分類を、上下線との両方向で使用できる信号設備（複線利用では閉塞区間があるが、単線で使用時は1閉塞扱い）を配置した。
