    BART to begin major track rebuild between South Hayward and Union City stations

    May 11, 2021
    The first weekend track shutdown for the work will be May 15-16.

    The Bay Area Rapid Transit (BART) is beginning a large construction project in southern Alameda County.  

    Crews will replace critical track components between the South Hayward and Union City BART stations, as well as begin preliminary work to create a storage facility at the Hayward Maintenance Complex for hundreds of new Fleet of the Future cars.  

    BART is targeting stretches of trackway in the system that are in the greatest need of replacement and prioritizing work on those sections. This critical work will replace nearly 50-year-old track infrastructure. Many of these aging track components have been in operation since the beginning of BART service in 1972 and have outlived their design lives.  

    Funding for the track replacement work is coming from voter-approved Measure RR. Funding for the new rail car storage facility is provided in part by a $1.17-billion grant from the Federal Transit Administration. The storage facility is part of the Transbay Corridor Core Capacity Program, which will dramatically increase the number of trains BART can run through the Transbay Tube. 

    Part of the project will involve the construction of a retaining wall. The equipment used for this part of the project installs the piles for the wall by vibrating the piles into the ground.  

    Once complete, BART passengers should experience a smoother, safer and more reliable ride. The new rail car facility will bolster BART’s service to San Jose as well as help to ensure BART is maximizing the number of Fleet of the Future trains in operation. 

    The project will require a series of weekend track shutdowns between South Hayward and Union City.  On those weekends, free buses instead of trains will carry passengers between those stations. Thirteen weekends have been scheduled for track shutdowns in South Hayward in 2021.   

    Additional shutdown weekends are expected spring through fall in 2022 but specific dates have not yet been selected. This is the initial phase of work at the Hayward Maintenance Complex with additional stages of construction likely to occur over the next several years. 

    Electrical cable replacement requires night and weekend work 

    Along with installing new rail components, BART will also replace the 34.5kV electrical cable to ensure trains have a reliable source of traction power. Replacing these electrical cables is also an important step in allowing BART to run more trains in the future. This work will be performed primarily at night but will also require some weekend days when train service between the South Hayward and Union City stations will be reduced to only one track.
