Representatives with one of the unions representing BART workers and the federal mediator in charge of trying to broker contract deals are saying they won't be going on strike Wednesday, and that they will continue to work toward a deal through Tuesday night.

"I have been authorized by the parties to announce that the negotiations are continuing under our auspices. Progress is being made," mediator George Cohen was quoted as saying in a release from BART management Tuesday. "Out of respect to the public and BART ridership I have also been authorized to announce that trains will be running all day tomorrow."

Bargaining was set to continue Tuesday night, representatives with one of the unions said.

"(N)o deal has been reached, however our negotiation team is still working and continues to do so through the night again," Amalgamated Transit Union Local 1555 posted to Twitter on Tuesday night.

BART's unions had said they could strike Monday, but they have put off a strike as negotiations have continued under the direction of a federal mediator. Commuters have expressed frustration with the ongoing uncertainty, and the late-night notice about the availability of train service; commuters weren't told that trains would be running Tuesday until 1 a.m. - three hours before train service would have halted if a strike had taken place.

Meanwhile, managers at AC Transit have asked Governor Jerry Brown for a 60-day cooling off period in an effort to halt a strike by the bus service's workers; Brown has not yet said if he will seek the cooling off period from a court. AC Transit's workers rejected a contract deal reached in August and a second deal reached on September 25; unions representing AC Transit's workers have said they could strike as soon as Thursday.
