One of the beam engines which powered the machinery in South Street Works survives and can be seen at Beamish Museum. This engine was built in the works in 1823.
The engine is of the 'grasshopper' design, which produced a more compact engine than a full beam. The column supporting the left-hand end of the beam is hinged at both top and bottom. Movement of the beam is guided by this column and the swinging links at the top right of the engine
