BART is replacing electrical lines that are critical for maintaining train service in that part of the system. BART has already been replacing traction power cables at different locations across the system. BART is reaching out to neighbors about potential construction impacts. The work will require that service be reduced to one track in Lafayette on several weekend days. The next work day for this project that will require single tracking is Sunday, September 19. Riders in the area should expect delays of 10-15 minutes.

This critical infrastructure provides power for our trains from the high voltage switching substation and supports redundancy for this portion of the BART system. This equipment is essential for ensuring reliable train service. This 50-year-old electrical infrastructure (part of the legacy system) has exceeded the end of its design life and must be replaced. Loss of power in this section of track without any backup would have major impact on train operations for the entire BART system.

In order to perform this critical job, BART crews will also be working nights to complete the work in this section of trackway. Neighbors can expect construction activities under our aerial trackway with the operation of construction equipment.
