Today, September 11, marks the 51st anniversary of the opening of BART in the San Francisco Bay Area.  As of 2023, the system serves 50 stations along 131.4 miles (211.5 kilometers) of track.  Needless to say, this is significantly more than the 12 stations and 28 miles (45 kilometers) that were opened on this date in 1972.

To mark its 50th anniversary last year, BART posted a variety of material about the agency’s history on its website and also held multiple events last September and October to celebrate the occasion.  Missed out on the festivities?  You can read all about how BART celebrated its golden anniversary on their website!  Make sure to check out the many historical stories posted on the website, including one about how BART could have been built as a monorail and another explaining why BART does not use standard gauge.
