Service for underground Muni trains traveling through San Francisco was restored after more than three hours Sunday afternoon because of faulty signals at Church Station.
Muni spokesman Paul Rose said all trains were affected.
“The signals are not communicating properly,” he said.
Operators noticed the signal problems around 11:30 a.m. Service was restored by 2:50 p.m.
Rose said most of the cars were running above ground, but would not enter the tunnels. Shuttles were put in place instead.
At Van Ness Station, Muni employees were directing passengers attempting to use the underground to Market Street for travel between Embarcadero and Church stations.
No announcements were made about the service change at Montgomery Station. A handful of people sat near the outbound train’s normal pickup area, surfing the Internet on iPhones or listening to music.
When no train had appeared for about seven minutes, David Siu, 33, and his family decided to try their luck at street level.
“The digital reader said there was an N-Judah in eight minutes,” he said. “But there’s been no announcement and it’s really quiet down here.”
Shana Valenzuela, 24, who lives in the Mission district, was hoping to take the J-Church home. But after 10 minutes without seeing a train go through the station, she too went to catch a bus line.
"Trains are usually a lot slower on Sundays,” she said. “I’m not surprised Muni did not say there was a problem (with the trains).”
