BART is currently running at what could be considered its maximum theoretical capacity given conditions. What I mean is that the built environment provides only unidirectional flow of passengers: toward SF in the morning, way from SF in the evening. With the addition of tracks to San Jose, this could change. We could start getting more flows of people where neither end is SF. That should boost ridership but of course they are adding a lot of miles.
