New York's governor says the operator of a train involved in a fatal derailment should be "disciplined in an appropriate way."
Gov. Andrew Cuomo made the comment about William Rockefeller at an unrelated event Tuesday.
Investigators have not determined whether Sunday's crash was caused by operator error or illness, a mechanical problem or some other factor.
The National Transportation Safety Board says the train was going 82 mph as it entered a 30 mph turn.
Cuomo called that a "gross deviation from the norm."
He said other agencies might want to take a look at the engineer's "behavior in operating the train."
Union leader Anthony Bottalico says he is confident the investigation will reveal "there was no criminal intent."
Four people died and more than 60 were injured in the wreck.
