Actually if the new technology being installed on the Jubilee Line works and is allowed to work to it's full potential, it really could improve capacity and journey times. It allows the train to run far closer together. But I still don't see it making Canada Water any easier to use. The trains are always going to be packed when they reach there having passed Waterloo and London Bridge on their way to Canary Wharf. On topic, I can't believe the proposal is to remove so many train services from SE London, especially those serving Kings. It seems ludicrous.
