I'm using Lac-Mégantic as an end point when I'm asking this question, so 2013.
In 2003, the work-rest rules for railways' operating employees were established with a requirement of fatigue management plans, and then that was updated and replaced in 2005. Then in 2008, Transport Canada established a working group to address fatigue, as well, and even brought in a university professor from Denver. That was again updated in 2011. Then Transport Canada's rail safety branch assessed the railway companies' implementation of these fatigue management plans and found that a lot of them did not meet the established criteria.
Why can't we put this to rest, the fatigue that's going on with the rail companies?
