As I mentioned earlier, we've invested in the last couple of years more than $80 million to improve safety on our own infrastructure. Thanks to the economic action plan, a portion of that money has been invested in making sure that all our public crossings on our own infrastructure are equipped with the most modern technology available. So they're fully protected with gates and lights.
We're also investing in what we call CTC, that's centralized traffic control, so there's no dark territory on our own infrastructure. So all the infrastructure is signalled. We've done also a lot of bridge repair, etc., but the work that we've done on our infrastructure to make sure that all our crossings, the public crossings, are fully protected, I think is the main answer.
I'd like to add to what Jean has mentioned on working with the community. For our locomotive engineers, who circulate on the network across the country every day, we have a responsibility. We initiated a program with them that I think is very unique where they identify every day if they see a fence that is broken, if they see a situation around the road that could cause a risk for trespassers who are crossing, and they report that situation to their manager, to the local committee.
Every month Steve and I attend a call and the managers have to report on situations that have been brought to the attention of the locomotive engineers. We take that and we go back to the community, the police, the school, etc., and we inform them about the situation that's been brought to our attention and we try to work with the community to reduce or to eliminate that situation. It's been done across the country.
