From what I have heard, the train crew was made up of one enginman and two conductors. One of the conductors had gone over to the single car (carrying lumber) in an attempt to apply the handbrake and it is possible that he managed to uncouple the car from the locomotive before it went over the side of the canyon.
The enginman either jumped or was thrown from the locomotive before it too, went over the side and he survived with non-life threatening injuries.
The other conductor went over with the locomotive and was killed.
The locomotive appears to be a GP40-2 without dynamic brakes, which is something that would not have been tolerated on that grade (2%+) or any other grade back in BC Rail days, as all BC Rail locomotives were dynamic brake equipped.
My condolences to the familys of the crew.
