In each of two round-trip services between Nishi-Maizuru Station and Amanohashidate Station, the train changes its train number and is operated as a local train (Tango Discovery nos. 64 and 72 are operated only on Saturdays and holidays as the limited express 'Tango-yuyu').
2往復とも、西舞鶴～天橋立間において、列車番号を変更の上、普通列車（64・72号は、土曜・休日のみ「タンゴ悠遊号」として運転）として運転する。
