Let me take a shot at that first.
As a service to the whole industry, we maintain a staff in the Railway Association of Canada who are the most expert people in the country on dangerous goods. They're located out west, in Toronto, and in Montreal. They work directly with the emergency response people from the railways if we have an incident. Their job is to monitor and advise on dangerous goods at an incident site. They do training of operational crews on dangerous goods. They're also very involved in any regulatory processes. You may be aware that new tank car standards were published very recently for Canada and the U.S. There's a consultation process going on with the supplier industry on that as we speak. These are the people who are involved in those sorts of matters.
