When changing trains from Keishin Sanjo Station to Keihan Main Line, passengers could pass through the ticket gate with a single ticket, but after the opening of the Tozai Line, they had to buy a new ticket (although the situation was improved to some degree on April 1, 2007, by the introduction of PiTaPa, a smart card for payment of amongst other things, railway fares).
京津三条駅から京阪本線へ乗り換える際は1枚の切符で可能であったが、東西線開通後は改めて切符を買いなおすことが必要になった（しかし2007年4月1日のPiTaPa導入である程度の改善は図られた）。
