BART crews will be working in southern Alameda County to replace 34.5 kV (kilovolt) traction power cables that provide electricity for trains.
Replacing these aging power cables is essential for ensuring the continuation of reliable service in this portion of the BART system. The work team will replace approximately 1,200 linear feet of traction power cable.
The work will be happening between the Union City and Fremont stations and will require BART to reduce service to only one track between those stations to ensure the safety of track crews. This work is expected to happen all day Sunday, September 26. Riders in the area should expected delays of 15-20 minutes. Future work on this cable replacement project is expected to take place on previously planned track shutdown weekends for system revitalization work near Union City. Those weekends are October 2-3 and October 16-17. You can learn more about the overall trackway replacement work happening near Union City here.
This work is supported by voter-approved Measure RR, which provides $3.5 billion for rebuilding BART’s critical infrastructure. The 2021 Measure RR Annual Report has details on the progress that’s been made in rebuilding the BART system.
