I'm very happy to talk about what we're doing in that space. Obviously, the first thing we want to do is to minimise the need for dealing with unexpected delays or cancellations. But whatever we do, and even if we had 100 per cent reliable infrastructure with a 100 per cent reliable fleet, our trains, unfortunately, would hit things on the line and, therefore, we will always end up with disruption.
Because of the nature of the tracks over most parts of the UK nowadays, particularly in Wales, we have large sections of single track running. Therefore, when things happen, they evolve quite quickly into significant disruption, because you're not just impacting the train that hits something, or that gets caught somewhere, or that breaks down, you're impacting everything that's behind it, and it takes hours, sometimes, to unwind that. So, having better information is really important.
It's also really stubbornly difficult to deal with. I think we went through a period where we found it particularly difficult to deal with, and that was when we were both dealing with infrastructure-linked disruption and had a shortage of rolling stock. The way that the railway, broadly speaking, works is it will have a plan, a very, very detailed plan, and if that plan can operate effectively, without interruption, the system works amazingly—everything's where it's meant to be, everyone knows where it is, and everything is fine. All information is perfect.
That then starts to fall apart if you have not enough rolling stock. Whilst it is falling apart, the people in the control room—controllers who have to try and piece back together 1,000 services a day in a new way—find that very difficult, whilst at the same time communicating to the general public through systems that are quite old-fashioned and quite difficult to get real-time information.
So, that's the backdrop, and that's where we've been. The two big things we have done—and then I will ask Jan just to give a bit more information, because Jan deals with this on a day-to-day basis—is firstly we have addressed the problem around lack of numbers of rolling stock, and I'm sure we'll talk about that later. Secondly, we have put our Twitter and comms teams into our control centres. That's a new thing for us. It took quite a lot of working through with the relevant teams, because the control centre is a controlled environment. It is a highly safety-critical environment. Therefore, putting 'people who just talk to the public' in there—I'm not personally downplaying that—is quite a radically different thing to do. But we have done that, and it is paying dividends.
The other thing we've been doing is to introduce a whole lot of new control staff and really encouraging, wherever possible, a customer-centric view of what you do in a situation where things are falling apart, so we want to focus on getting the customer where they need to be, rather than getting the train where it needs to be, but there are trade-offs, as Jan I'm sure will cover.
