There are really three elements to this recommendation. The first is group planning. You take a look at your route and choose the safest route over which to carry those dangerous goods. If there's only one route, then you move to the second element, which is an examination of train operations to make sure that the operations on that route, whether it's the chosen route or the only available route, have the highest safety standards.
We would be looking to the railways to look at such things as track-side testing, speeds, ensuring that the equipment is of the highest standard, things like that, to make sure that they're playing the A game, really, on those routes.
Then what we've asked them to do is not make it static. You don't just put this in place and then move goods over that route for the next 20 years. We want them to follow up with risk assessments on an ongoing basis to make sure that the control measures they have put in place are working. You can have an accident with the same consequences as Lac-Mégantic that is caused by something totally different.
What you need to do is bring down the risk in the whole system that there are going to be accidents, derailments, for instance. You want to bring down that whole risk.
