Last Monday, the Mayday Bank Holiday, we went to have a look at the steam engine in Trencherfield Mill at Wigan Pier. The mill was opened in 1907 and operated until the 1960s.
The mill machinery used to be powered by a massive 2,500 hp steam engine with 4 cylinders. The power being transfered from the engine via a 26-foot flywheel with 54 ropes. Today it can be visited on Sundays with “steam days,” when the engine is operated, taking place intermittently.
It’s the world’s largest working horizontal triple expansion steam engine.
