SC train derailment caused by bouncing wheels

LIBERTY, S.C. (AP) - A freight train operator says bouncing wheels on one railcar was among the causes of a 24-car derailment that led to the evacuation of 436 homes in northwestern South Carolina.

Norfolk Southern told The Greenville News on Friday that its own investigation of the June 10 derailment near the town of Liberty showed that wheels of a railcar were bouncing from side to side as the train slowed down.

Norfolk Southern spokesman Robin Chapman says the condition known as truck hunting is hard to detect.

The Federal Railroad Administration says the northbound train was traveling at 47 mph on the main rail when it jumped the track, causing more than $1 million in equipment damage and $650,000 in track damage.

Residents were evacuated as hazardous waste spilled from tankers carrying isopropyl alcohol and ethylene glycol.
