I'm going to give you an example of when I was with Transport Canada in the civil aviation world. I looked after their operating certificates, mainly the same as with rail.
When our inspectors used to go out and do these inspections, that's when they would catch, or find, issues with the companies' safety programs. When they announce that they have to go, and they have to give them so much notice, it gives the companies time to, for a lack of better words, clean up and hide some of the problems they have been dealing with.
That's why it's so important that the random and unannounced inspections are happening. That's when I used to see a lot of notices of suspensions towards the company—operations were suspended until they fixed these problems. Right now that tool is no longer in place, and it doesn't give me the warm and fuzzies when it comes to the safety of rail.
