Operation Pattern

In the daytime, trains from Keisei Tsudanuma to Chiharadai station and Shin-Keisei through services from Matsudo to Chiba-Chuo run at 20-minute intervals. On the Keisei Chiba Line, trains operate at 10-minute intervals. All trains are at most 6 cars long due to the platform length restriction at the intermediate stops between Keisei Tsudanuma Station and Keisei Chiba Station. Four-car trains were also used on the line, but they were discontinued at the start of the 8 December 2018 timetable revision.^[3]

There are also trains to and from Keisei Ueno Station on the Main Line during mornings and evenings. In the morning, trains towards Keisei Tsudanuma operate at the same 10-minute interval as other trains, and trains towards Chiba Chuo operate every 6 to 10 minutes.
