A US passenger train that derailed, killing three people, was travelling at 130km/h on a curve with a speed limit of 48km/h, data from the train's rear engine indicates.
It happened in Washington state during rush hour yesterday.
Officials say 100 people were taken to the hospital.
The train crashed shortly after leaving a new station on its inaugural run.
Authorities said all carriages had now been searched, but would not rule out a rise in the number of fatalities.
