UPDATE 10:48 AM A San Francisco Municipal Railway bus engine overheated and caught fire Tuesday morning, briefly blocking traffic on U.S. Highway 101, according to Muni and California Highway Patrol officials.
It was a filter in the bus engine compartment that overheated and went up in flames.
The bus was not in service and had no one on board besides the driver, who was not injured, Muni spokesman Paul Rose said.
The fire was quickly put out and the bus was eventually able to drive away shortly before 8 a.m. after blocking the far right southbound lane of the highway, CHP officials said.
