First of all, Transport Canada, as the regulator, does have regulations with respect to fatigue in a number of modes and certainly in rail and air. From the point of view of the Transportation Safety Board, we always look to see if fatigue may have been a factor in any mode of transport we investigate. When we find it, and when we determine that it did have an impact on crew performance, then we cite it as a finding in our report, either as a causal or as a risk finding.
With respect to crew fatigue in the rail industry, in 2016 when we issued our current watch-list, we did identify crew fatigue in the rail industry as a watch-list issue. We highlighted a number of investigations where we'd reported it as a causal factor, a risk factor, and we are looking to see that Transport Canada work with the railway industry to require fatigue management plans for the railway industry to mitigate the risk of fatigue.
