An Update: The investigators recovered the 2nd data recorder, the engineer's cell phone, and the videos from the front facing camera, all from the front of the train that crashed into the station. They have determined from them that the train entered the station track at 8mph (within the speed limit) but accelerated to 21mph while entering. They also determined that the engineer applied the emergency brake approximately 1 second before the point of impact.
This does not bode well for the engineer. I think he can kiss his career goodbye.
