In the counsel, Kyoto City suggested an idea of passing the area to the north of the existing route with a mountain tunnel from Yamashina and connecting the line directly to downtown Kyoto; however, Keihan Electric Railway disagreed with the idea, insisting that the passenger transportation volume wasn't sufficient for the two lines to compete with each other, so eventually both sides agreed to discontinue the section between Keihan-yamashina and Sanjo on the Keishin Line of Keihan Electric Railway and allow Keihan Electric Railway to use the Tozai Line, Kyoto Municipal Subway.
その協議の場において京都市側は、山科から現ルートよりも北側を山岳トンネルで貫いて京都市都心部へ直行する案を提示したが、京阪電気鉄道側が両線が競合するほどの輸送量は無いとこれに反対し、京阪電気鉄道が京津線の京阪山科～三条間を廃止し、京都市営地下鉄東西線へ乗り入れることで決着した。
