Project Steam is a railway preservation society based in Dunedin, New Zealand.
The society is currently the only one of its kind in Dunedin; the Ocean Beach Railway operates small tank locomotives but on private trackage, and the popular Taieri Gorge Limited is run solely by diesel locomotives.
The two locomotives were built in 1885 by Nasmyth, Wilson and Company, entered service in 1887, were withdrawn in 1928, and on 8 August 1932 were dumped in the Clutha River near Beaumont to protect the Roxburgh Branch from erosion.
Project Steam's first home was a location by the Water of Leith in central Dunedin.
All other components such as spare wheels, old tender bodies and the boilers were moved to a field next to the Taieri Gorge Railway at Sutton.
