DEER PARK, Texas -- A train hit a bus on Tuesday morning, injuring dozens of Shell plant contract workers, KPRC Local 2 reported.

The collision happened on Shell property in the 1500 block of Highway 225 near Center Road at about 7:40 a.m.

Thirty-two patients were taken to five hospitals for treatment.

Two people suffered serious injuries and remained hospitalized Tuesday evening.

Donald Coffey, a contract worker at the plant, was on the bus.

"I can't explain it, man. It's like something in the movies. (The train was) 20, 30 feet from us, coming right us," he said. "We all hollered at (the bus driver). It was probably 20 or 30 of us guys hollering, 'Hey, hey.' Bam."

Investigators said the train was moving at about 10 mph and was not towing any train cars. There are no crossing arms at the intersection.

"For this particular location, a stop sign is in regulation with … there is compliant with all regulations," Shell spokeswoman Emily Overton said.
