UPDATE: 6 p.m. EST — The death toll has now risen to four in Tuesday’s collision of a freight train and charter bus that appeared to be stuck on the tracks in Biloxi, Mississippi.

The four were among 43 people on the northbound bus, which had traveled from Austin, Texas. Three people died at the scene and the fourth died later. Two people had to be removed from the wreckage by a Jaws of Life, Incident Cmdr. Joe Boney said. Thirty-five people were hospitalized, several airlifted from the scene.

The CSX train was heading east when it collided with the bus, which had become stuck 5 minutes earlier, witnesses said. A nearby car, which was not involved in the crash, was used as a stepladder to get people off the bus.

The accident was the second in two months involving a train and a vehicle in Biloxi. A Pepsi-Cola delivery truck was hit by a CSX train Jan. 5 when it became stuck on a steep upgrade. The truck driver managed to escape before the impact and called for help.

Ameet Patel, senior vice president of regional operations for Penn National Gaming, owner of Hollywood Gulf Coast Casino and Boomtown Biloxi Casino, said the bus was headed to Boomtown from the Hollywood casino.

All train traffic in the area has been halted.
