Curve is rated for 30 mph and he was entering it at 82 mph had been reported from the black boxes. Either the brakes failed or the engineer was negligent in some way. Perhaps pushing the cars ahead of him rather than pulling them contributed to his forgetting the curve ahead. Sad thing to occur anyways.

We had a far too fast into a curve case up here in Canada not that long ago as well. Again it also was a commuter train but cannot remember if there were any casualties.
