This will be as complete a list of engine houses and major opening and closing dates of all the mines featured on this website as possible.
If I find a engine house record that goes something like “had a such and such engine by this date” with no definitive build date I’ll stick a ‘?’ in front of the date, and I’ll do the same if it’s the first time the engine is mentioned in text, like a sale date. Any houses without a build date will be left off for the time being.
