Kyoto Bus started its business as a relatively small company of 27 employees and 14 cars, having inherited from the former two companies the nature of a suburban bus company in the Rakuhoku and Rakusai areas; however, after the war it gradually resumed the operation of the routes that had been suspended until the merger, thanks to the improvement of the situation surrounding the supplies of materials and fuels.
京都バス（株）は合併前の両社からそれぞれ洛北・洛西の郊外バスとしての性格を受けついで発足し、事業規模も従業員27人、車両数14台という小規模な企業体であったが、戦後資材・燃料などの事情も好転してきたのに伴い、合併前に休止していた路線も徐々に復活していった。
