Thank you for the question, Mr. Barsalou-Duval.
Yes, there are multiple modes of communication.
I think the communication breakdown was twofold. One of the messages we sent out from central that was direct by email to passengers on train 55 was in error. We said that the tree had been removed. It had not been removed. That was due to a communication issue we had with CN. We provided the wrong information to passengers directly. Obviously, they didn't take it well, because they saw that the tree was still there. That was a failure. From an on-train perspective, we had offered the same information to our crew, so they had the wrong information and they were conveying that to passengers. That creates anxiety and mistrust on the train.
In terms of other modes, as you mentioned, instead of using the audio system on board the train, part of the effort of the crew is to actually walk through the train and on a one-on-one basis, row by row, actually be present and visible, answering questions as they go along.
We had a multipronged approach. If there's something further that we can do, we will be looking for that in our efforts with regard to the review we will be doing.
