I will try to answer your first question, and my colleague will jump in on the dangerous goods aspect.
On the first one, let's be clear about that. We do inspect the railways. We do inspections. That's why we have inspectors. We do audits of their practice to see if they have integrated safety practice. We do investigate when an accident happens, as does the TSB, Transport Safety Board, and we do take enforcement measures that can go with, of course, AMPs, administrative monetary penalties for example, or we can go also, of course, with criminal charges. That is something that we do, actually.
