BILOXI - A witness says the conductor of a freight train was slowing down and trying to stop before colliding with a charter bus, but still slammed into it.

Four people were killed and more than three dozen injured in the Tuesday afternoon collision in Biloxi, Mississippi.

Biloxi native Mark Robinson tells WLOX-TV that he saw passengers who were trying to get off the bus either thrown beneath it or run over by the train. He says "body pieces were thrown everywhere."

Authorities said it took more than an hour to get everyone aboard the bus out of the wreckage. Two people had to be removed with metal-cutting equipment.

The CSX Transportation locomotive pushed the bus about 300 feet before coming to a stop with the mangled bus still straddling the tracks.
