This telephone exchange retains its original built-in automatic exchange equipment invented and designed by Mr Strowger and made by Siemens Brothers. The exchange also contains an early mobile exchange, which could be installed to give up to 100 self-contained lines at very short notice. It also retains all its original cabling and wiring allowing many of the original equipment to still function. The building's former generator room still survives, as do the recreation room and other facilities provided for the men who looked after all this equipment. The building also contains a "shelter" installed during the Cold War era to provide protection for those manning the station during a nuclear attack. This building now houses the Institute of British Telecommunication Engineers Museum of Telecommunications. (LB Online)
