Commuters who use a San Francisco light-rail line were facing delays after an accident on the system's F line.
Officials say six people were injured in an accident involving two San Francisco Municipal Transportation Agency trains and an SUV on San Francisco's busy Market Street around 5:45 p.m. Monday.
Monday's crash comes after 47 people were hurt in a crash involving two Muni trains on July 18.
None of the injuries appeared serious, but Muni spokesman Judson True said the driver of one of the trains was taken to the hospital for treatment of what appeared to be non-life-threatening injuries.
After the accident, Muni was transporting passengers in shuttle buses around the damaged trains.
The cause of the crash is under investigation.
