Thank you all the same for making that distinction. We've gone from one step to a big step. I imagine we're ahead.
I'll now go back to Mr. Hackl and Mr. Benson.
As far as the recordings are concerned, which have created quite an uproar, I think we agree. The TSB asks for access to the recordings to conduct its investigations, and you are prepared to give them, as long as the recordings remain confidential. I think we agree on that. That said, it is a post-accident measure. You have given me a glimmer of hope as to possible measures to counter fatigue.
I would like to address one last point with you. For decades, Canada's rail industry has relied on a visual signal system to control traffic over a significant portion of the network. It has also been more than 15 years since the TSB has steadily emphasized the need for additional physical defence. We are talking here about alarms. It even asks that the train be automatically stopped if the driver misses a signal, for instance. Bill C-49 says nothing about all of these measures. In my opinion, these are genuine rail safety measures, since they allow pre-accident response, not post-accident analysis.
Where do you stand on these measures? I would like to hear your views on establishing additional physical defences on locomotives.
