Shall I start on this one, and maybe take a step back? So, the step-back position, I guess, is that it is the Welsh Government's policy position that rail should eventually be devolved. Personally, and I think in my role corporately, I would say that that's the right thing to happen. If you look at the performance of the core Valleys lines, where we own and run all of it, in comparison with Wales and cross borders, the gap is about 20 percentage points. So, that's a real gap. That is not me in any way doing a disservice to the people who work very hard in Network Rail to run the Wales and cross-borders network. It's just about an integrated railway, controlling mind, and people feeling that they own it, including one Government owning the services and the track.
So, that's the direction that we want to go in. The Railways Bill is really an enabling framework, and the detail that follows I think is what determines how effective it is, I would say, both for England and for Scotland and Wales. For Wales, the minimum we have to have, in my view, is that the ability to work more efficiently across track and train that GBR will be granted in England needs to be granted to us for CVL in Wales. The Welsh Government have clearly stated that that is what they expect to see through, in effect, the enactment of some secondary legislation. All of the conversations we've had with the DfT have been positive on that, but obviously until it happens, it doesn't happen. So, we have to have the ability to integrate CVL and remove some unnecessary bureaucracy.
The second thing that we have argued for is around the creation of an empowered business unit within GBR for Wales. Now, this would still be ultimately accountable to the UK Government, because it's non-devolved, but at least we would have an entity that is similar—well, it would be smaller than TfW—but that, in theory, ought to be able to keep pace with us. At the minute, if we want to do things with a huge public body in England, they cannot keep pace with us, just because of their corporate governance. Frankly, Wales is on the corner of their business, so they're not very interested.
But, really, what we would want is to get that empowered business unit, at least in part accountable to TfW, so it is, in turn, accountable to the Welsh Government and to committees such as this. If you think about it, infrastructure exists for the trains that run on the infrastructure. The trains that run on the infrastructure exist for the benefit of the people and communities who use them. So, to have an edifice on which you say the track is the thing that's really important and we won't integrate it is just really quite weird.
So, I am hopeful that we will make progress. The legislation allows for progress to be made, but the detail of what is in the memorandum of understanding, what is in that secondary legislation and, frankly, the behaviour set and the instructions given to GBR will be really important as we move forward, and I don't think this is a one-time option either. I've heard a lot of people say that this is the only time that we can make any changes in rail. We think about what the Welsh Government did on CVL. The Welsh Government did that, actually, at a time of differential politics between Wales and the UK, and through hard work without a process, we got something devolved. So, I think we should get everything we can out of this, and then I think we can constructively go back for more.
