The Society was formed in July 1992 after Sir Norman Longley had the idea to preserve the signal box — which had became redundant as a result of signal modernisation in 1986 — and an inaugural meeting was organised by local historian Roger Bastable. The society purchased a lease for the building from Railtrack in the 1990s.

It was originally built by the London, Brighton & South Coast Railway, probably in 1877. As well as containing a lever frame by Saxby & Farmer (No. 2621), it is an excellent example of Victorian brickwork, and is well-known as a landmark. The signal box was Grade II listed in 1983.

The Society publishes a magazine, Signal four times a year. Click here to download a sample copy.

Membership of the society is £15 per year.
