On Sept. 11, 1972, the very first passenger embarked on the very first BART line, which ran between MacArthur and Fremont stations.
Since that fateful day, millions of people have turned to the Bay Area Rapid Transit System to get them to work, home or the next Giants game.
This September marks 40 years of service for BART , a huge milestone for the entire agency, its employees, and of course, its passengers.
In honor of the big 4-0, BART is exhibiting various memorabilia and photos from the last four decades throughout its stations.
