Yes. Thank you for the question.
We already spoke about the weather. What makes it difficult for us when there's an incident like this is that we need to access the site. As we know, some of the roads and major highways in Ontario, like some of the 400 series, were closed at some point.
On top of accessing the location of the derailment, the location of the derailment itself was extremely difficult. The derailment occurred really close to a creek with a narrow passage from a bridge to access the derailment site.
We have to remember that this derailment involved two trains. The cars of 122 came in contact with the locomotive of train 305. Both tracks at the time had cars and locomotives derail. Normally, when we access a site, to be able to remove a derailment really quickly we use all the space we have. In this case, we were working in a really restricted area.
As an example, we also use contractors to support us, not only people from CN. Normally we can use the contractors and the heavy equipment they have and position it at the site, so we can start working in parallel. Because of the location of that derailment, we were forced to bring one piece of heavy equipment at a time to do its portion of the work, then remove it and bring another one. We could not even use our track as a space because another train was derailed on it.
It was the location of it, the fact that dangerous goods were involved, and the fact that we were in proximity to a creek and had a really narrow space to access the point of the derailment that made it much more complicated. Of course, there was the weather, as we spoke about earlier. When you put all of that together, the effects compounded.
I just want to point out, though, that once inside, our people worked 24 hours non-stop. It's wasn't only the people of CN, but also our contractors, who did a great job supporting us. We worked 24 hours non-stop to re-establish the network as fast as we could in this situation.
