A spin-off effect of such construction was the assurance of fare collection from passengers on the turnaround trains then being operated by Keihan (by purchasing a special ticket and getting on at Tofukuji Station for Shichijo Station and then transferring to a Keihan super express made it possible to go as far as Yodoyabashi Station) (special tickets for turnaround trains are currently not sold and it's necessary to purchase a ticket again at Shichijo Station).
なおこの構造のため、当時京阪で行っていた折り返し乗車（専用乗車券を購入することで例えば東福寺駅から一旦七条駅に向かい、京阪特急に乗り換えて淀屋橋駅に行くことができた）の料金収受を確実にできるという副産物もあった（現在折り返し専用乗車券は発売されておらず、七条駅で再度乗車券を購入する必要がある）。
