What to do with this extra cash? If Governor Jerry Brown's $611 million budget is approved, BART officials are proposing to spend it on new seat covers and cushions, cleaning up silver cars, improving escalators, upgrading the system's rail to make the trains quieter and possibly run trains late at night. The surplus is the result of an increase in the number of riders, sales tax revenue and a hiring freeze a few years ago. The next BART fair increase isn't scheduled until July 2012. If the surplus ends up being less than the projection, the projects will be completed according to priority.
