Interesting that they are doing the "Waterloo and City line" first and for background, that is a isolated line/train that just goes from Waterloo station to the City central. I used that many times in the past and out of all the lines, was more civilised - would have commuters line up along the platform were the doors would appear once the train stopped and really a contrast to other tube/train stations. So for a first trial/go of converting existing stock/track - that I will agree is a perfect choice. Now when they get to the circle line - that IMHO will be the hardest and as a commuter.
