Hayward Maintenance Complex

BART needs increased maintenance capacity as part of its Fleet of the Future program. The Hayward Maintenance Complex (HMC) will ensure that BART’s maintenance and repair capacity is sufficient to support the new railcar fleet for both the current system and system expansions.

Hayward Maintenance Complex (HMC) project would consist of acquisition and improvement to three properties on the west side of the existing Hayward Yard for a larger primary repair shop, a new component repair shop, a vehicle overhaul shop, a new central parts warehouse, and a new maintenance and engineer­ing repair shop.  It also includes the construction of additional storage tracks for a maximum of 250 vehicles on undeveloped BART property on the east side of the Hayward Yard.

Part of the "Big 3"

BART has prioritized three interrelated capital investment initiatives to ensure the system can safely, efficiently, and comfortably serve current and new riders.  They are known as the “Big 3” and include the Fleet of the Future, an improved train control system to enable trains to operate more frequently and this new maintenance facility to maintain and store the expanded fleet.

The “Big 3” together can address some key current bottlenecks that hinder BART’s ability to meet current and future ridership growth.

Funding and Phasing

The HMC will cost approximately $432 million, and a funding plan has been developed by BART and the Metropolitan Transportation Commission to cover the full project cost. Creation of the HMC is jointly supported by BART and the Santa Clara Valley Transit Authority (VTA). Environmental clearance for the HMC project has been approved, cost-sharing agreements with VTA have been ex­ecuted, and design work is currently in progress.
