Just for the record, during our aviation discussions on SMS, it was very clear on the record that reporting increased by 400% to 500% where SMS had been properly implemented and where there was immunity.
My question, however, has to do with the railway operating certificate. I'm curious. You've stated that current operators, the ones that are already operating, would get their rail operating certificate almost as a right, although it could be withdrawn if there were reasons to do so.
Given the fact that most of the problems we've discussed about rail safety involved the current operations of railways, why would you have this kind of grandfathering?
