I don't know if I would use the same qualifier. I think “significant” is a word that everyone measures in a different way. We definitely saw that they took action. There was an increase in the number of inspections. There was more rigorous follow-up on corrective actions, as we talked about earlier. In our sample, in 92% of the case files we looked at there was a follow-up on corrective actions, and they had been taken.
We saw an increase in risk-based planning about oversight activities. What's missing now is making those linkages of collecting data and using that data to inform future risk-based information. More importantly, what we think is one of the key fundamental gaps.... There are actually two. One is measuring the effectiveness of the safety management systems of the rail companies. Then it's to make sure of the overall effectiveness of all of this increase in activity and to make sure it's directed in the right places and having an impact on rail safety overall.
