From http://www.light-straw.co.uk/ate/ar2/kelvintrunk.html Trunk Control Centres 1949-1951 By 1945, 40% of trunk traffic was controlled by local auto-manual centres, but this still had to be routed via Faraday and thus to give relief, three Trunk Control Centres were planned: TCC City opened in Monarch Telephone Exchange in 1949 TCC Bloomsbury opened in Museum Telephone Exchange in 1950 TCC North opened in Kelvin House, Judd Street in 1951 In November, 1947, the International Radio Exchange moved to the top of Monarch Exchange building, and in January 1949 Trunk Control City, the first of London's Trunk Relief exchanges was opened. Even prior to this date Faraday had not controlled all the Trunk traffic originating in the London Group. Trunk Control North Trunk Control Centre (TCC) North, which was planned to house two manual board units, opened in a new building at 123 Judd St , London, WC1 on 30 April 1951. This was part of a policy to devolve Trunks into separate centres, starting in 1949, owing to the vulnerability of a centralized Trunk system.
