Traction power cable replacement work in Union City

BART crews are 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.

When the work is happening near the Union City Station BART will reduce service to only one track to ensure the safety of track crews. Riders in the area that day should expect delays of 10-15 minutes. Passengers will board trains traveling in both directions on Platform 1 at Union City Station. 

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.
