Among the retired cars, there had been four cars of the old series KuMoHa 51 (train series 51 with a cab-equipped motor coach) which remained in operation until the last moment before the renovation of the Keihanshin Local Line, among which KuMoHa 51010, equipped with Garland ventilator, was transferred to the Chuo Line, and the three other cars (51028, 51038 and 51056) were remodelled into new series MoHa 51 (train series 51 with motor coaches).
しかし、最後まで残った旧型車の中にはクモハ51が4両残っており、中でもクモハ51010は中央線投入組の生き残りで、新造時のままのガーランドベンチレーター装備車であったほか、残りの3両(51028,51038,51056)はモハ51として新製された。
