Officials say a faulty bearing caused the derailment of a train hauling molten sulfur in Florida.
The Lakeland Ledger reports that a passerby called 911 early Monday to report sparks near one of the wheels just minutes before nine of the 192 total cars left the tracks near Lakeland. A preliminary investigation released Tuesday by CSX officials says the cause was a faulty bearing on an axle of one of the rail cars.
The derailment spilled 3,000 gallons of molten sulfur, a hazardous chemical. Another car leaked 12,000 gallons of cooking oil. A busy road near the tracks was closed for more than 36 hours.
CSX officials say they're monitoring air quality to make sure nearby residents are safe.
