- Discover the machinery that powered mills all over the North West and helped to shape our world. Once a railway transit shed, the Power Hall is now home to some of our locomotives, rolling stock and a huge collection of engines. Watch daily demonstrations of gas, electric and diesel engines. Learn how energy is converted into power, from the early water wheel and the horse gin, through to vast horizontal steam engines. Look out for the impressive 1907 McNaught Engine, which powered Firgrove Mill in Rochdale. See our replica of steam locomotive Novelty, which ran in the famous 1829 Rainhill Trials and is a forerunner to the largest machine in the Power Hall, the Beyer-Garratt articulated steam locomotive. Made at Beyer, Peacock and Company’s Gorton factory in 1930, this Garratt ran on the South African Railways until 1972.
