Oral Answers to Questions — Post Office. – in the House of Commons at on 12 December 1938.
asked the Postmaster-General on what date the Park Telephone Exchange was converted from manual to automatic working; and whether the conversion took place without interruption or inconvenience to the public?
The Park Telephone Exchange was converted to automatic working at 2 p.m. on Saturday, 3rd December. Apart from a few minor troubles, which must be expected in a transfer of this magnitude, the conversion was quite satisfactory.
Will my right hon. Friend give an opportunity to subscribers to visit the exchange and see the working?
Yes, Sir. If the subscribers realised that 4,447 lines were transferred in seven minutes, they would realise that there must be some delay at the moment. They would be most welcome to see the exchange.
