Uniformed Department of Homeland Security officers seen patrolling BART trains and stations Tuesday are members of a Transportation Security Administration team, according to BART officials.
Photos posted to social media, including a
tweet by Janice Li, a San Francisco local running for the Bay Area Rapid Transit Board of Directors, show a line of at least eight armed, uniformed DHS officials walking in the aisle among seated passengers on a train bound for the Civic Center BART station in San Francisco.

Article says they're patrolling with BART officers. I'd be a little worried if they were out there on their own as there are some very special procedures involved to stop trains or drop the power to the third rail, something that's done pretty frequently when people get on the tracks.
