Hopefully this might mean BART runs past 12. This is impossible. Unlike NYC's subway, there is not a third set of rails (in enough places, at least) to keep the system online 24 hours a day, while being able to perform track maintenance. Washington DC's subway is the same way and will never be a 24 hour system. It would be a better use of time to invent a teleportation device, than to wish that many of the country's subways ran 24 hours a day. EDIT: typo
