LAKELAND, Fla. (WTSP) -- CSX’s preliminary investigation found a faulty bearing on one of the cars caused a train to derail in Lakeland Monday, spilling thousands of gallons of molten sulfur.

The Federal Railroad Administration is conducting the formal investigation into the cause. They tell us their findings won't be available until February.

Meanwhile, crews cleared the tracks where the derailment happened. A different trained moved through the area much more slowly Tuesday morning.

Cars had to find another route. Part of Kathleen Road remained closed Tuesday.

“Oh, the traffic's horrible,” Ginger Pollino, who lives nearby, said.

She's not concerned about the thousands of gallons of molten sulfur that spilled.

“I guess if you live near a train track, then you're susceptible to things like that that could potentially happen,” she said.

The cars that carried the chemicals were moved from the track to the other side of the street, about 100 yards from Matheau Francis’ house. He is concerned about the chemicals.

“Drinking sulfur ain't good,” he said. “If it gets in the water table, you're going to get sick. A lot of people around here are going to get sick.”

CSX is handling the cleanup. Florida DEP is overseeing it. A spokesperson for CSX wouldn't answer 10News’ questions on the phone, inquiring about when the company last did maintenance on the tracks or cars.

Instead, the spokesperson referred us to a statement, in which CSX assured neighbors the sulfur didn't get into the groundwater. Their tests found no sign of dangerous chemicals in the air either, according to the release.

“There's a lot of questions I guess we'll never have answers to,” Pollino said.

Neighbors hope they can trust the company that caused the spill to clean it up too.
