Sources: NTSB To Cite 'Operator Error" In Deadly Amtrak Derailment In Philadelphia

PHILADELPHIA (WJZ)-- Multiple sources tell CBS News that the NTSB is expected to cite operator error as the cause of an Amtrak derailment that left eight dead in Philadelphia.

According to the Associated Press, a U.S. official briefed by investigators says an Amtrak engineer was distracted by radio transmissions before his train derailed.

The official was not authorized to comment publicly because of the ongoing probe and spoke to The Associated Press on the condition of anonymity.

It's unclear what radio transmissions investigators are citing.
