The bus caught fire and flames were shooting out of the back.
"How did it catch on fire, sir?"
"I don't know."
"How did you realize it was on fire?"
"Someone behind me came up."
That was the bus driver. He says another driver saw the fire when they were at a light and pounded on the window to tell him. Some of the passengers said they smelled something odd, and asked the driver to pull over.
They were traveling from Sacramento and about a block away from the Stockton station.
No one was hurt. The driver says it looks like a mechanical failure caused the fire.
