Isambard Kingdom Brunel built this engine house at Totnes to power the South Devon Railway's atmospheric trains but it was never used for this as they decided to use conventional steam locomotives before the line was opened this far. It was later used as a milk processing factory when the brick chimney replaced Brunel's decorative Italianate one. It is currently empty and looking for  anew use.
