SAN FRANCISCO (AP) — Trains in San Francisco's subway system were halted during the Monday evening commute because of a problem with the system's signals, a transit spokesman said.
All underground trains in the San Francisco Municipal Transportation system were stopped because of electrical problems caused by a transformer that blew near Muni's Van Ness station around 5:45 p.m., said Muni spokesman Paul Rose.
Stranded passengers were being taken by bus shuttles between the Embarcadero and West Portal stations.
Crews were working on restoring service, but Rose could not say when the subway trains would be running again.
In a separate incident, a woman in a wheelchair was hospitalized with life-threatening injuries after she was hit by a Muni train around 5:30 p.m. near Church and Market streets, said San Francisco police Officer Carlos Manfredi, a spokesman for the department.
Because the woman was trapped underneath the train, special equipment had to be used to lift the train up so she could be freed, Manfredi said.
Investigators were interviewing witnesses and would try to determine if the incident was recorded on surveillance video.
Rose said the two incidents are unrelated.
