After the war, Keihan Electric Railway separated again as an independent entity in 1949; however, the Shinkeihan Line and its three feeder lines, the Senriyama Line (the section from Awaji Station and to the north of the current Senri Line), the Juso feeder line (the section from Awaji Station and to the west of the current Kyoto Main Line) and the Hankyu Arashiyama Line, remained as a railway of Hankyu Corporation because the trains of the Shinkeihan Line had shared the track of the Takarazuka Line since 1945, arriving at and departing from Umeda Station, etc.
戦後、京阪電気鉄道は1949年に再び分離発足することになるが、この際に新京阪線の電車は1945年から宝塚線へ乗り入れを行って梅田駅発着となっていたことなどの理由から、同線と支線の千里山線（現在の千里線の淡路以北）・十三支線（現在の京都本線の淡路以西）・阪急嵐山線は阪急の路線として存置することになった。
