[data] from Railway Codes, of course. Where else?
The British railway is, for a variety of reasons, awash with acronyms and codes of various kinds. This web site sets out to explain some of these related to the infrastructure and to operational issues. Not included in this site are abbreviations of company names or information about trains themselves: this information is available elsewhere and the editor's main interest lies in infrastructure.
Taking Aspley Guise as an example, the codes BBM and MD140 apply to the route on which Aspley Guise station sits, and APG, 138000, ASPLEYG, and 62051 (ASPLY GSE) apply to the station itself. All of these codes mean different things, and are used in different ways. This site helps to explain these codes.
Also on this site are lists of pseudo-legal data. The first is a list of British railway services introduced under special legislation. This legislation allows operators to consider certain services as 'experimental' and withdraw them if considered necessary without going through full closure procedures. The second is a list of licences and licence exemptions issued by the Office of the Rail Regulator. There is a list of routes designated as community rail partnerships, and finally a table of franchises with associated dates.
Information about other assets such as signal box prefix codes, electrification mast codes, stations, depots and tunnel lengths is also available here.
For more information about day to day changes with Britain's railway infrastructure, please refer to the infrastructure section of the Railway Observer.
Most of the information contained in this site has taken many hours and letters to different companies to compile: it is hoped that you, the reader, will find it helpful to shed light on some of the codes found in railway documents. The records contained in this site are as complete as possible. If you are able to add to the data, please contact the editor.

Can you help the editor identify some old photographs? These are shown here; page updated occasionally.
Your photographs! Alnmouth station was officially renamed in 2003 to include the line 'for Alnwick'. Can you supply an image that clearly shows the earlier succinct name sign, taken post privatisation (1 April 1994), please? It doesn't have to be directly of the sign; clearly legible but secondary to another subject is fine.
Railway uniform neck ties, specifically:
§ these purchased and promptly lost at Ashford station after the 24 August 2025 open day. Did you find them?
Reasonable costs paid: please contact the editor if you can help. Thank you.
Additionally, the editor has two uniform ties that are unidentified, shown here. Do you know which organisation issued them?
Does your company use these pages? Let the editor know to be added to the list

You will find a small collection of railway photographs on the editor's Flickr pages. It is hoped that you find them enjoyable and a little different to the usual 'front three quarters in countryside' views. Click on an image to go to the photos.
