Federal investigators will meet next week to detail the probable cause of last year's fatal Amtrak train derailment in Philadelphia.
The National Transportation Safety Board's meeting Tuesday in Washington will be held just over a year after the crash that killed eight people and injured more than 200 others.
The New York-bound Northeast Regional train entered a sharp curve at 106 mph, more than twice the speed limit, last May 12 and tumbled off the tracks.
The train's engineer told investigators in November he remembered pushing the throttle forward to pick up speed and then braking when he felt the train going too fast into the curve.
The engineer said there were several gaps in his memory and that he didn't remember what happened between throttling up and the curve.
