From the NTSB's press conference:
<> From the NTSB event recorder findings:
<> Preliminary info from event recorders shows train was traveling at approx 82 mph as it entered the 30 mph curve.
<> Approximately 6 seconds before the rear engine came to a stop, the throttle went to idle.
<> Approx 5 seconds before the engine came to a stop, pressure in the brake pipe dropped from 120 psi to 0 - which resulted in max braking.
<> We do not yet know the initiating event for the throttle going to idle or the brake pressure dropping to 0 psi.
<> There were 9 station stops prior to the derailment. We are not aware of any prior issues with the brakes.
