San Francisco BART riders were hit with "major delays" Thursday morning after travel was halted between 24th Street and Colma for about 20 minutes.

According to BART, at 10:55 trains stopped traveling "between 24th and Mission and Colma Stations."By 11:18, they had "restored normal service between Colma and 24th Street Stations," but continued to warn that riders should still expect "a major delay on the San Francisco Line in all directions."

According to BART spokesperson Alicia Trost, an equipment problem on a train and subsequent track realignment in Daly City caused the service disruption.

By 11:50 a.m., delays for riders had been downgraded from "major" to "10 min," and Trost said that things should be back to normal well before the evening commute.
