AC Transit Adds New Buses to Transbay Routes
AC Transit is deploying new MCI D45 coaches to its Transbay routes connecting the East Bay with San Francisco, transit officials said. The buses will be introduced gradually over the coming months, though officials haven't specified how many vehicles are being added or the exact deployment timeline. The Transbay routes serve thousands of daily commuters traveling between Alameda and Contra Costa counties and San Francisco's employment centers.

Transbay Service Upgrade
The new coaches represent an upgrade to one of the Bay Area's most heavily used transit corridors, according to the transit agency. Transbay routes provide critical connections for workers, students, and residents commuting across the bay. Officials said the deployment aims to bring modern amenities and improved reliability to the service, though specific details about features and capacity weren't available by publication time. AC Transit operates the Alameda-Contra Costa Transit District, serving the East Bay region.
Fleet Details
The MCI D45 CRT LE coaches will be integrated into existing Transbay operations, transit officials said. Officials haven't disclosed the total number of buses being deployed or the cost of the fleet acquisition. Funding sources for the purchase weren't specified, and it's unclear whether federal, state, or local dollars are supporting the upgrade. The agency didn't provide information about which specific Transbay route numbers will receive the new vehicles first or whether all Transbay lines will eventually operate the new coaches.

Rollout Timeline
The buses will enter service gradually over the coming months, officials said, though a specific completion date for the full deployment wasn't provided. The phased approach is designed to integrate the new vehicles smoothly while minimizing service disruptions, according to the transit agency. Officials haven't said when riders can expect to see the first new coaches in regular service or how long the complete rollout will take.
Rider Impact
Commuters can expect enhanced comfort and potentially improved on-time performance as the new buses enter service, transit officials said. Specific details about onboard amenities and seating capacity weren't immediately available. Officials said they'll release additional information as the deployment progresses.
