Youtube had an NTSB update about 3 hours ago. They have retrieved the black box and found the locomotive and train was going between 75 and 78 mph. The allowed speed limit for passenger trains on this stretch of track is 79 mph. Additionally the train had not reached the nearest switch, so, presumably mis-aligned points would not be a cause. This would seem to exonerate the engineer......but we must wait for a more thorough investigation to be completed.
A very disheartening turn of events.
