Thank you for the comment.
What's important to understand is that railways don't sell or produce what they transport. This means that we depend entirely on the demand of our customers and the service provided at the destination.
In my opening remarks, I talked about an integrated system. That's really important because, for us in the rail sector, if volumes double, we will inevitably have to invest in our own infrastructure, just as others will have to invest in theirs, particularly ports and so on. As I said, where and to what extent those investments will be needed will depend, in our view, on demand at the time.
