OAKLAND (CBS SF) — BART service was halted Monday morning through the Transbay Tube to and from San Francisco after a power pole toppled near the West Oakland station, draping a high-intensity line across the tracks.

The transit agency issued a tweet around 8:30 a.m. saying the downed wires forced all service to and from Oakland West to be halted.
