A federal investigator says there is indication of a link between today's New York commuter train derailment and the derailment of a freight train that occurred in the same location in July.
"We will be looking at that, but at this point, we have no indication that it's a factor," National Transportation Safety Board member Earl Weener said.
Mr Weener said investigators would be on the scene of the crash in the New York city borough of the Bronx for seven to 10 days.
