I thank the noble Baroness for her question. I am as aware as she is that level boarding is a really important consideration for many people, including those with disabilities. However, even in respect of HS2, it is a complicated subject because there are relatively few HS2 stations and, as it is now configured, those trains will serve many stations on the conventional railway network, at which platforms have been at differing heights for as long as they have been built, in some cases going back to the 1840s. However, the point she raises is really important; the point she raises about Old Oak Common is important, and the point about Old Oak Common is equally complicated, because Old Oak Common will not merely serve the new HS2 trains in their new station—at which level boarding will be relatively simple—but will also serve trains on the conventional railway network on both main and relief lines out of Paddington, which have themselves several different floor heights. We need to crack this problem, and I am very sympathetic to the point raised by the noble Baroness, but it is more complicated than it might sound. I will give her the assurance that she wants that we are actively considering it, because building new railway stations is very expensive and takes a long time and we should try to get it right.
