So, the budget’s, obviously, been an exceptionally difficult set of circumstances. For rail in particular, this has been an issue ever since the pandemic hit. So, the current budget difficulty is not the first time that rail has been involved in this. In fact, I recently said to the First Minister that I had about eight halcyon weeks in post after the last election before I realised that I was just going to spend all of my time talking about rail budgets. That's because we've done something unique in Wales—we've nationalised the railway, but we also took responsibility for the core Valleys lines network, the actual infrastructure. Network Rail is not responsible for that; they are responsible for everything else, but they're not responsible for that. So, that means there's a particular set of investments and opportunities that we want to be able to do, and TfW is not a private company, so they can't raise money in the way private companies could. So, they're reliant on us to be able to facilitate them to get their farebox up enough for us to free up enough money to invest, and for us to have a plan in place to invest.
Our plan to invest was very much based on passenger numbers before the pandemic. There's not getting away from that. And those passenger numbers were severely disrupted, both during the pandemic, when, obviously, they stopped altogether for a time, but then didn't recover, and then have recovered differently, as we've already discussed. There's no getting away from the impact that that has on the budget, because the farebox—. The cost of the railway is £550 million-ish. The farebox is around £200-250 million. The difference is what we have to give them, and that difference can vary considerably. So, that's very top of the line. Peter will give you more detail if you want it.
So, we really need to make sure that, on the investment that we put in place, we basically hold our nerve. So, we keep the investment going in order to get that farebox up. Because if we don't do that, we will, absolutely and inexorably, end up paying more for a worse railway. So, paying more is inevitable. We're either paying more for a better railway, or we're paying more for a worse railway. Those are the two options. There isn't an option of 'don't pay more', unless we shut the whole railway down, which quite clearly isn't an option. So, I do think getting your head around the basics of that is one of the first things you have to do.
So, we've had to provide the funding upfront, both capital funding for the core Valleys lines, which was the first budget problem we had, going back—as I say, my time sense is terrible—to 2021, before Peter joined actually. I think, when he joined, he had a bit of a crash course in where we'd been so far. We had to sort out the core Valleys lines investment, because without that, we cannot get all the things Luke's just been talking about; we can't do that. You can see that happening; you can see it happening on the ground, as the lines are worked on. They're not there yet, but you can see the hoardings and all the rest of it going up everywhere.
