However I am concerned that they are addressing the symptom not the problem, which is the lack of capacity on the Victoria line itself.
People have to be locked out because there are simply not enough trains to take them away even at the 2min headways now in use.
What is required, and required urgently, is increased north/south capacity from Victoria, preferably at standard gauge; links with Crossrail and Thameslink would obviously be advantageous. There is even a fantastic construction compound available at Battersea.
Perhaps the giant new northern concourse is being built that size in anticipation, I do hope so.
