Cleanup continues at the site where a train carrying 35 cars derailed on Tuesday in Palo Pinto County. Due to damage sustained to some of the cars, officials began a liquid flare operation on Wednesday to safely dispose of the propane the damaged cars were carrying. That operation will continue throughout the day Thursday.
