I don't have all the underlying activity data. That is one of the challenges and one of the initiatives we are working on with Transport Canada and the railway industry, including the major railways and the Railway Association of Canada.
If we look at a million train miles, there were 79 million train miles travelled in 2021 versus just over 80 million train miles in 2020. There's a difference in activity level, but we don't have a good way of calculating a rate.
Uncontrolled movements can happen in yards; they can happen on the main track or on a secondary track. The issue is trying to calculate a rate. We just don't have that activity data to calculate a rate when it comes to uncontrolled movements, but it's one of the issues we're working on with Transport Canada and the industry.
