For reference, the camera is part of their equiv. of a black box system. It also records speed, throttle position and brake application and settings. This train had multiple locos and when they do that the rear most loco faces aft, that is why you get a camera view. The camera for the lead loco would also have any conversation from the crew, but I haven't found that one posted. The video IS verified genuine.
They had one tank car with some VERY nasty stuff in it that fortunately did not rupture. Another one with nasty, but not quite so nasty, stuff did rupture, forcing the evacuation of the surrounding area.
