One would probably be anonymous reporting. They have a system down in the U.S. It's a pilot project done by the FRA. They have a close-call reporting process down there, by two railways. I think one is the Union Pacific and I think CP has just signed on down there. It's where a third party actually takes the calls. So anybody can call in a near miss, so there's a process that's going on there. We're actually exploring that at CP as well. What we're struggling with, again, is the anonymity of it. So that would probably be the first one.
The second one would be investigations for contributing factors rather than what happens in a lot of cases, I believe more on one railway than others. They get to one fault and they say that's it, whereas in any incident or accident there are contributing factors of five, eight, or ten items that need to be fixed, such that if you took any one of those out, it wouldn't have happened.
So I think that would probably be two items.
