I've spoken to CN workers in my community, and they speak of very poor morale within the culture of CN. You're probably correct in saying that a big part of the problem here is that within certain of our railways we don't have the culture that enables SMS to work properly.
The evidence from our aviation safety review was very clear. The main airlines in Canada started implementing safety management systems well ahead of time, before the legislative structure was even in place, and it was actually working. But that's not the case with rail. I think that's going to be part of the final report we have coming out of this review. Some legislative changes will probably be needed to make sure that SMS actually does the job for which it was intended.
