On positive train control, we are following very closely what is happening in the U.S., and we've been doing studies of train control in Canada. Last September or November, we shared with this committee a copy of the report of the Advisory Council on Rail Safety, which did an analysis of train control.
The conclusion was that positive train control, in its current form, was not something that we should be pursuing in Canada. Advanced train control technologies are definitely something that we should do, and we will continue to do those assessments. We are currently working with the rail research group at the University of Alberta to conduct further analysis. We will be happy to share future reports with the committee.
