It really is a very well-implemented project. I also went for a ride on the first train through the tunnels on Sunday, and the impact it's going to have on a lot of journeys across London was pretty clear. It's not absolutely perfect. The absence of step-free boarding at the stations shared with National Rail infrastructure is unfortunate, and some of the interchanges with other lines involve annoyingly long paths. But these are compromises and I really hope some of them can be rectified in the future. But the design of the stations, the lighting, the trains… just all absolutely first-rate.
