We're working on that, definitely. We've very aware, as I said to Mr. Barsalou-Duval, that it's an absolute priority.
However, let me ask you a question. It's not spin and it's not political or this and that. If I changed the fleet tomorrow morning and I had 100% diesel locomotives, or I waited a few years to get hybrid locomotives, is it worth it or not? Honestly, I'm reflecting on that too, because if I were to buy today and renew everything, I would be getting the same type of polluting locomotives.
