Well, we had to, didn't we? After all, it's not every day a new Tube extension is opened. I decided not to try to get the very first train along the new branch, as that would have meant somehow getting to Battersea Power Station for 5:30 am and I wasn't too sure how I could do that. But as I was going to Walthamstow anyway for grandmother duty, I thought right, I could explore on the way home.
The Swan Whisperer decided to come with me, and so we went off together to pick Boy 2 up from school and encourage him to practice the piano and get changed into football kit ready for training later. The Boy, meanwhile, is now at secondary school and stayed late to try out for the football team, which he was - and we were all - delighted he was selected for! So we are very proud grandparents, as well as nerdish!
And then it was time to go home, and the Daughter dropped us off near the Tube station, and we went normally as far as Warren Street, where we changed for the southbound Northern Line. When we got there, this was the signage for the next few trains:
But, as you see, a train pulled in just then, and I realised it couldn't be the Kennington one and, sure enough, it was going to Battersea Power Station, so we got on.
I don't often seem to go down the Charing Cross branch of the Northern Line, for some reason, but it was fairly familiar, until we got to Kennington. There may be trouble ahead but today everything went smoothly. I don't know how many people were going just to say they had, as we were, but the train was still quite full when it arrived at Nine Elms. There is an island platform there, but if you are thinking of Clapham North and Clapham Common, don't. It's about the same size as Canary Wharf, and looks very like it, only no platform edge doors.
We didn't get out, although we were tempted, but carried on until we got to Battersea Power Station; again, huge wide island platforms, then a short-ish escalator leading up to a mezzanine floor where tickets could be bought, I think there may be a public toilet (but wouldn't swear to it), etc. Then a longer escalator to the surface - and a fairly amazing view of the new station with the eponymous power station in the background. 
And only a short walk to the terminus of the P5 bus, which took us home nicely in time for the supper that was waiting for us in the slow cooker!
