Officials in Biloxi, Mississippi, said four people were killed and more than 40 injured on Tuesday when a freight train hit a charter bus.
Witnesses told WLOX the bus, carrying passengers from an Austin, Texas, senior center to a casino, was stuck on the tracks when the train slammed into it. A spokesman for the city of Biloxi said there are signs at the crossing that warn of a low ground clearance, but he did not say if that's what caused the bus to stop on the tracks. He also said nine of the injured passengers are in critical condition.
The city has a high number of train crashes for the area, officials said, and the mayor wants to close some of the rail crossings. The site where Tuesday's accident took place was not slated to be closed.
