The stations are wheelchair-friendly, with elevators, narrow gaps between platform and train, and no height differences at places like restrooms.

As a result of negotiations, Kyoto City and Keihan Electric Railway agreed to establish a Third Sector (public-private partnership) company to obtain a Type-3 railroad business permit and control the tracks, while the City of Kyoto would obtain a Type-2 railroad business permit and operate the trains on that section.

The section from Daigo to Nijō opened in 1997, and the Keihan Keishin Line was integrated from Misasagi to Kyoto Shiyakusho-mae.

The reason it did not originally continue to the (then-)terminus at Nijō was for the Kyoto Municipal Transportation Bureau to keep the calculated costs of running the trains balanced.

However, since the opening of the extension in 2008, this is no longer the case and trains of the Keishin line now continue to the present terminus at Uzumasa Tenjingawa.

A plan exists to extend the Tōzai Line as far west as Rakusai in Nishikyō-ku, but for the time being, the extension will be stopped at Uzumasa Tenjingawa; prospects beyond that are as-yet still unclear.
