BART operates six named and interlined heavy rail services plus one separate automated guideway line. Five of the heavy rail services run through Oakland, and all of those but the Berryessa/North San José–Richmond line and the SFO–Millbrae shuttle go through the Transbay Tube to San Francisco. All six services run on weekdays until the end of the afternoon rush hour; evenings (after about 7:00 pm), nights (after about 9:00 pm), and Sundays have as few as three services operating. Three of the services change terminals at certain times so that all stations are served during all service hours.
