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. Underground Tours can now be booked and will be back on 2 April 2025.
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.
