Thank you for the question.
My answer will be threefold.
First, the rail tragedy in Field, British Columbia, is still under investigation by the RCMP.
Immediately after the Field incident, there was a train with a crew nearby and with the emergency brakes on, and it started to roll. Transport Canada, within a very short period of time—I can't remember, but Mike could say; it was probably like hours and days—put in place an additional requirement on the train securement rules, essentially requiring.... It added a very clear standard for handbrakes on unattended trains at grade, even if they are unpowered.
I think the member is right. There was an incident recently of a train in a similar area that didn't have the handbrakes applied. It turns out that the principle of the rule that we put in place immediately after Field was clear: If the train is unattended, you have to put on the handbrakes according to a formula based on the number of cars and the grade. That wasn't done.
There was, I would say, a difference of perspective as to whether or not the train was unattended. The clarification of the rules was not to say that unattended trains have to be secured; that was established across Canada in a very unambiguous way immediately after Field. Rather, it was a clarification that in Transport Canada's view, these conditions make for an unattended train, and in those conditions, you have to put on the handbrakes according to the formula.
Mike, do you want to elaborate on that? This is a specific incident that we've taken quite seriously and that I know you've been following closely.
