Update: Broken Gas Line on Caltrain Tracks Capped

The gas flow to a line that broke in San Bruno this evening should be cut off by around 11 p.m., according to Pacific Gas and Electric.

The 2-inch gas line was broken around 8:18 p.m. by construction workers near San Bruno Avenue, PG&E spokesman J.D. Guidi said.

Workers should be able to cap the gas flow to the line around 11 p.m., but there is no estimate yet on how long repairs will take once that occurs, Guidi said. The gas leak has halted Caltrain in both directions, according to Caltrain spokeswoman Christine Dunn.

Northbound train 447 was stopped at Millbrae, and all passengers have transferred to BART. Southbound train 448 stopped at South San Francisco, and those passengers have been taken by bus to Millbrae, where they can board a southbound train, Dunn said.

Caltrain is reaching the end of its normal service day. The last northbound train left the Diridon station at 9 p.m. and 448 is the last southbound train, Dunn said.

BART is accepting Caltrain tickets and SamTrans is providing a bus bridge between Millbrae, San Bruno and South San Francisco.

The line was broken by a construction crew working on the San Bruno Grade Separation Project, Dunn said. The construction is part of a $155 million project that will elevate train tracks over three streets in San Bruno.

San Bruno Avenue has been closed since Friday at 5 p.m. and is scheduled to remain closed until 5 a.m. Monday due to the project. No injuries or evacuations have been reported.
