BART's Normal Service Restored Following Transbay Tube Electrical Issue, Major Delays

The electricity issues that have plagued BART's Transbay Tube beneath San Francisco Bay since Friday morning have been resolved.

A BART spokesperson said late Friday evening that power issues in the Transbay Tube have been rectified and BART trains are no longer single-tracking through the tube between Oakland and San Francisco.

The electricity problem was initially reported at 7:11 a.m. when an electrical overcurrent caused a breaker to trip offline, taking a segment of rail in the tube out of service and forcing a San Francisco-bound train to go back to the West Oakland BART Station, where it offloaded its roughly 200 passengers around 8:35 a.m., according to BART.

Until late Friday evening, trains single-tracked through the Transbay Tube except for a brief time Friday afternoon, when Transbay Tube service stopped completely in order for BART work crews to inspect the problem area. Single-tracking resumed shortly after 2 p.m. and had expected to last throughout the rest of the day.

BART officials warned earlier in the day that a fix was not likely to take place before the end of the day because it would require stopping all service again for an extended period of time.
