SAN FRANCISCO (CBS SF) — BART is recovering from earlier major delays on the San Francisco line Tuesday evening because of an equipment problem on a train and a problem in the trackway, BART officials said.

An alert about the delay, which is in the San Francisco International Airport, Millbrae, Daly City and East Bay directions, was sent out at 5:54 p.m.

That alert came after an earlier tweet by the @SFBARTalert account.

While both that account and the more general @SFBART account posted that the system was recovering, @SFBARTalert tweeted shortly before 6 p.m. that the major delays were continuing.

It was nearly an hour later that the @SFBARTalert account once again retweeted that the transit system was recovering from the ongoing problems.
