The Ellenroad Trust Ltd was established in 1985 to ensure the preservation of the Ellenroad Engine House and Engines. The Trust arranged the refurbishment of the boiler house and the engines and started to run the site as a steam museum. The Engine House was then scheduled as a National Historic Monument and the Trust is the legal guardian of the site.
The Ellenroad Steam Museum Society Ltd was formed as ‘The Friends of Ellenroad’ and is tasked by the Trust to carry out the day to day activities on the site. It maintains the building, engines and exhibits and organises the monthly steaming days when the Engine House is open to the public. At the present time it is entirely run by volunteers.
