SAN FRANCISCO >>Police arrested an SUV driver who shut down San Francisco’s subway system for more than two hours after the vehicle went onto the underground tracks.

Muni spokesman Paul Rose says the vehicle entered a tunnel on Church Street shortly before 6 a.m. Thursday and drove eastward almost to the Van Ness Station. It stopped when it got stuck on the tracks.

No trains were involved, and no injuries were reported.

Muni manager Tyronne Julian chased down the vehicle and says the driver appeared intoxicated.

All underground train lines were shut down during the morning commute while crews removed the vehicle and inspected the system. Trains resumed service by 8:15 a.m.
