Metrolink's express service between downtown LA and Antelope, Santa Clarita valleys starts in May

The express trains will begin operating May 9 as part of a six-month pilot project.

"This new service will eliminate 32 minutes each way for Antelope Valley commuters and Santa Clarita Valley commuters will save 15 minutes each way to and from Union Station," according to Los Angeles County Supervisor Mike Antonovich, a member of the Metrolink Board of Directors.

"Eliminating nine stops, the Antelope Valley express train will make just two stops between Palmdale and Los Angeles Union Station -- at the Santa Clarita Valley and downtown Burbank stations," he said.

The express trains will have up to six cars, he said.
