Since becoming independent and the opening of Keihan Oto Line in 1989, the Eizan Electric Railway gradually showed a characteristic of Keihan; particularly, after the Keifuku Electric Railroad sold its shares to the Keihan Electric Railway in 2002 due to the deteriorating conditions caused by the train crash on the Echizen Main Line of the Keifuku Electric Railroad, and became a wholly owned subsidiary of the Keihan Electric Railway, the Eizan Electric Railway has been gradually showing a characteristic of Keihan rather than Keifuku.
独立後、1989年の京阪鴨東線開業あたりから、徐々に京阪色も出てきていたが、2002年に京福電気鉄道が京福電気鉄道越前本線列車衝突事故による経営悪化のため所有株を京阪電気鉄道に売却し、同社の完全子会社となって以降、京福色から徐々に京阪色の色合いが濃くなってきている。
