Planning for Bay Area Rapid Transit (BART) began in the 1950s after the Key System had been dismantled. The first passenger embarked on Sept. 11, 1972 on the first BART line, which ran between MacArthur and Fremont.
BART says we can expect to hear more about the 40th anniversary year in coming weeks, including special promotions and events.
