Given such a background, the lines belonging to Hankyu Railway (except for the lines included in the Kyoto Main Line system) are sometimes called the Jinpo Line, after the combination of the first Chinese letter of the lines, in order to distinguish one from the other.
またこのような経緯から、京都本線系統の路線を除いた阪急各線をその頭一字を取って神宝線と総称し、お互いを区別することがある。
