When Rakusai New Town was constructed on the city's outskirts, many people moved in because they'd heard that the subway line would be extended up to this area in the future, and thus most were very hopeful regarding the extension of the line; however, the plan is nowhere in sight because of the strained state of Kyoto City's public finances (for details, see "The plan for westward extension").
市の郊外に洛西ニュータウンが建設された際、「将来ここまで地下鉄が来る」という話を聞いて入居した人が多く、住民から延伸を望む声が強いが、京都市の財政事情が厳しいことから建設の見通しは立っていない（詳細は西部への延伸構想）。
