I think it's important to start by differentiating between the safety management system and an inspection. An inspection looks at the equipment, the tracks, the equipment, the crossings, and whether they're operating as intended or are defective or need to be repaired. The safety management system, as I said, is about the culture, that big framework within an organization.
We recommended in 2013 that a more risk-based approach was needed for inspections. What we found in our follow-up audit was that they were absolutely doing more inspections and that they were now doing risk-based inspections. In fact, they were doing risk-based inspections, random inspections as well as reactive inspections.
All of that is great. It feeds into the safety management culture that you should have in an organization. But then the audits, when they identify weaknesses, should also feed into determining where an inspection should go.
We definitely saw an increase in inspections, but there is still an opportunity to make sure that those inspections, when they are risk-based, are targeting the right companies and the right risks.
