WASHINGTON (Reuters) - An FBI examination of the Amtrak train that derailed in Philadelphia last week killing eight people has found no evidence that damage to the locomotive's windshield was caused by a firearm, the National Transportation Safety Board said on Monday. The NTSB said it has not ruled out the possibility that another object may have struck the windshield. (Reporting by Eric Beech; Editing by Eric Walsh)
