SAN FRANCISCO, Calif. -

Striking San Francisco Bay Area rail workers and transit agency officials plan to resume talks, as the walkout enters its fourth day.

Bay Area Rapid Transit spokesman Rick Rice says negotiations are scheduled to start again at 11 a.m. Thursday.

Talks between the nation's fifth largest rail system and its two largest labor unions went late into the night Wednesday before adjourning.

Union officials declined to characterize the state of the talks.

But in a statement, BART says it was sorry that the actions of the unions had caused such a tremendous disruption.

Key issues in the labor dispute include salaries, pensions, health care and safety.

Commuters are getting a reprieve from crammed buses and bumper-to-bumper traffic thanks to the Fourth of July holiday.
