Rail traffic across the Altamont Pass in unincorporated Alameda County was stopped early Thursday after Pacific Gas and Electric contractors spotted what may have been a gas leak in Livermore, according to Union Pacific Railroad and PG&E officials.
The railroad was notified of the leak around 12 a.m., Union Pacific spokesman Tim MaMahan said, who added all train traffic over the pass has stopped and won’t be restarted until the repairs are completed.
