The short answer is that there has been an increased cost as a result of extreme climate change and extreme conditions. That is something that all of the railways are planning for in their contingency plans. One thing that I think the railways have been doing more and more of is reaching out to other subject matter experts in meteorological changes or extreme weather patterns. Analytics are being used. Short-term and long-term forecasting is now in place. Contingency plans are done on a regional basis as well. I think it's something that the railways are all taking seriously. It's all part of their future planning.
Yes, there has been a significant amount of investment and there has been a significant allocation of time and people's resources to make sure that we can plan as best as we can and anticipate as quickly as possible when those events occur.
