Bay Area transit agencies are getting $45 million dollars in federal funds to upgrade infrastructure and improve service. Local officials Monday joined Federal Transit Administration Deputy Director Therese McMillan to announce the grants.  McMillan says a large portion of the money will go toward replacing aging fleets of diesel buses throughout the region.

"These buses have logged in thousands of miles over many years," she says.  "And importanly, they're being replaced with clean, fuel-efficient hybrid vehicles that also improve the beautiful environment we all love and respect here."

The funds will also go to a variety of other projects, including installing real-time departure screens in BART stations and expanding Muni's Rapid Network Service.
