Let me just add one thing. We've been focusing a lot on identifying the things that go wrong, or mistakes that may be made in the locomotive cab, but it's also a way of capturing best practices and sharing best practices across the locomotive, engineer, and conductor workforce, in terms of why it is that some people do certain things that keep them from maybe missing a signal or that improve communications within the crew. If those best practices can be shared as part of the initial training, etc., that's just going to help the system overall.
