British Power Signalling Register

The British Power Signalling Register compiled by Andy Overton is a free listing and historical analysis of all power signalling equipment installations commissioned in Britain from 1883 to the present day, excluding those on London Underground and metro networks. Aimed at both the signalling enthusiast and the professional engineer alike, the documents present in one place –

The lists are combined in a single Microsoft Excel (XLS) format file which can also be read by a number of competing software products. Within the file, the lists are combined into a set of cross-referenced spreadsheet pages to enable the use of data analysis, filtering and sorting tools.

A supporting text document in PDF format provides a comprehensive explanation of the technology and its development in easy to understand language, and features around 190 photographs to aid identification of designs. In order to fully understand the register you should read through this document first.

Strict definitions of panel types are provided, utilising industry-accepted names where already in use, with new sub-categorisations to add detail. Power signalling technology can now be referred to with the same universal understanding enjoyed by mechanical lever frames following earlier categorisations of that equipment.

The British Power Signalling Register represents a condensation of many decades of recording and research by a large number of signalling enthusiasts and industry professionals, and has been fully peer-reviewed by signalling historians and signalling engineers. It is intended to be a living, up to date register of the past and current British power signalling scene and updated versions are produced from time to time.

This web site is now the only authorised source for these documents. To maintain accuracy and version control, please do not host them anywhere else. Put a link to this page instead!

Both the author and the Society are grateful to Danny and Luke for previously hosting the register on their Heritage Operations Processing web site.
