IMPORTANT UPDATE: 08/01/2025 – Due to today’s icy conditions, the museum and its outside spaces will remain closed. We hope to reopen as usual tomorrow.
Please note that we have temporarily paused our iconic Underground Tours until April 2025, to install a brand new winding engine. The Museum remains open with a brand-new Time Tunnel experience now bookable.
This twin cylinder haulage engine made by John Mills and Company haulage engine, has a two-section drum which suggests that it was used to power a main and tail haulage.
