I can't pick out any one particular one. Certainly the larger class 1 railways would typically have more infrastructure internally to support their safety management system, but in our belief, any commercial operator, regardless of mode, should have a means to manage their safety risks. That requires some sort of institutionalized and documented formal process for identifying hazards and mitigating risks. That said, I can't say that we've seen a specific difference between the two through our investigations.
