I remember that incident well. It was a tragedy. In its immediate aftermath, as the member indicated, we issued some ministerial orders to enhance train securement. This was in direct response to what we saw there. A couple of years later, we did discover another train that we felt was unsecured. I think it provides a very good example of our oversight program and the tools we have in place to take immediate action. As a result of these, our inspector on the spot was able to act and react accordingly.
I'll ask Mike to elaborate on what we're doing from a rules perspective to even further enhance safety.
