Officially, the Kyoto Main Line is from Jūsō to Kyoto-kawaramachi, however, all trains run beyond Jūsō to Osaka-umeda terminal, using the eastern tracks of the section exclusively.

The Kyoto Main Line was constructed in the following phases:[1] Prior to the merger of Hankyu Railway (then Hanshin Kyūkō Railway) and Keihan Electric Railway in 1943, the line and its branches were owned by the latter and called the Shin-Keihan (New Keihan) Line.

[2] Originally projected for a 2020 completion, various delays have pushed back the start of operations on the new tracks to 2031.

[4] A loop line from Juso to Awaji via Shin-Osaka Station, to provide a direct connection to the Shinkansen has been proposed, but is not currently scheduled for construction.

Thus, in operation, Nakatsu Station is not listed on the Kyoto Line.
