I would say that the issue of fatigue has been an area of continuing discussions. I'm not able to comment on the various reviews or updates you referred to, but in the new SMS regulations that came into effect on April 2015 have strengthened the requirement for railway companies to take into account signs of fatigue in scheduling their employees. We continue to look at that aspect as we start audits in April.
I should add that under the advisory council on railway safety, which includes railway companies, Transport Canada, and bargaining agents, there was a working group set up to look at the issue of fatigue and to bring forward recommendations to the minister. That working group has since been disbanded because the members of the working group could not agree on specific recommendations to be presented to the minister. The department is now taking a look at what is coming out of the audits, but we intend to engage with all the players in terms of how we'll move forward on this file.
