Some trains are eight cars long, but the through trains between Kyoto and Osaka are operated with seven cars (because Chushojima Station or the further stations at which the local (semi-express) train stop only permit trains with fewer than seven cars).
8両編成の運転もあるが、京阪間通しの列車は7両編成での運転である（中書島以遠の普通（準急）停車駅が7両編成までの対応のため）。
