The Signalling Interest Group of Western Australia (S. I. G. W. A.) began life in 1994, as the research arm of the Claremont Signal Cabin Group. Whilst concentrating on the history of the signalling of the railways of Western Australia, SIGWA members also have a broad interest in history, railways and naturally enough railway signalling from at home and abroad.
SIGWA members have been active in supporting various community events such as 'Trek the Trail' held annually by the Shire of Mundaring. These 'treks' are a fantastic way to discover the history and beauty of parts of the former old Eastern Railway lines that once wound it's way up through and along Western Australia's Darling Scarp.
From time-to-time, SIGWA members undertake research outings to places of signalling interest. In the past these outings have taken the form of bicycle rides along the old, abandoned railway formations, or bus tours to a former station that had been threatened with redevelopment. The aim being to document what was about to be 'lost' to history 'before the event'.
