SAN FRANCISCO (KRON/BCN) —  A San Francisco Municipal Railway cable car and a garbage truck collided in the city’s Nob Hill neighborhood this morning, taking several cable car lines out of service, according to Muni officials Wednesday.

Muni officials tweeted about the collision at 9:20 a.m. at Mason and Jackson streets involving an outbound cable car on the Powell/Mason line.

Four people reported injuries in the collision, but none required transport to a hospital, according to Muni spokesman Paul Rose.

The collision stopped service on the Powell/Hyde, Powell/Mason and California lines, which were served by buses until around 12:30 p.m., according to Rose.

Service has since been restored to all lines.
