According to "Tetsudo Yoran (Railway Directory)," this line's starting station is Yodoyabashi Station; however, Sanjo Station is the operational starting station and the train heading for Osaka from Kyoto is denominated as the 'outbound train' and the train heading for the opposite direction, 'inbound train' (the same as the Hankyu Kyoto Main Line).
なお、当線は『鉄道要覧』では大阪の淀屋橋駅が起点として記載されているが、運行上の起点駅は京都の三条駅であり、京都から大阪に向かう列車が「下り」、その逆が「上り」となる（阪急京都本線も同様）。
