Jubilee Line signals
Last month, the Overground was officially the most reliable train service in the UK. The Jubilee Line, by contrast, continues to deliver a shocking service.
The BBC reports that we only had 78% of a proper service in 2009/10 and explains that the particular problems of the last few weeks relate to the new signalling technology that all the disruption of the last few years has been for.
The trains and the stations aren't talking to each other properly at the moment, but things are apparently getting better and we should have the full new service by June "at the latest", although the last time we heard, it was supposed to be fully operational in the Spring.
