In 1933, Britain's first route-setting power signal box using a swithc panel rather than a lever frame opened at Thirsk, to the specification of the LNER's signalling engineers A F Bound and A E Tattersall, forming the template for many such future installations on the nation's railway network. Larger schemes to a similar design followed at other locations on the former North Eastern Railway network, such as Hull Paragon (1938), Northallerton (1939) and York (1951 - the resignalling project was interrupted by the Second World War and not completed until after nationalisation). Thirsk signal box itself, after various alterations over the course of its life, eventually closed around 1989 under the York IECC signalling scheme.
