The first stage was completed last year, when we stopped using the most dangerous tank cars for transporting hazardous goods. We eliminated at least 5,000 of them. We did that thanks to one of our protection guidelines.
As for the DOT-111 tank cars, when we published our regulations in May 2015, we estimated the number of those cars to be about 150,000 across North America. We estimated the Canadian fleet to have contained about 7,500 of them when the regulations on the new requirements came into force.
We are currently looking at the transition of companies when it comes to the configuration of the TC-117 tank cars and the new configurations that will go into effect as of May 2017. We have made sure to be on the same page on both sides of the border with our U.S. counterparts.
