This locomotive was built by Hudswell Clarke & Company in Leeds in 1924 for Armstrong, Whitworth of Tauranga for the construction of the Waihi to Tauranga section of the North Island East Coast Main Trunk Railway.
It is only one of seven steam locomotives built by Hudswell Clarke to operate in New Zealand and one of the three such engines to be preserved.
The Public Works Department (PWD) normally built the New Zealand Railways but the government decided to test the performance of the PWD with a major private contractor. The contractor chosen was part of the British firm of Sir W G Armstrong & Co Ltd. It has also been suggested that this avoided the government from acquiring equipment that they did not need for long term use. The contract was completed in March 1928 and the locomotive was offered for sale..
After six years the locomotive was sold in 1930 to Milburn Lime and Cement which is just South of Dunedin. It stayed there until 1967when the works closed. The locomotive was then sold to the Waitaki NZ s Pukeuri Freezing Works for $1500.
In 1988 the locomotive was leased to the Weka Pass Railway at Waipara. The eight mile line runs through rugged terrain and includes lengthy gradients so it is perhaps not surprising that the locomotive ended up being of no use.
In 1989 the locomotive was loaned to the Oamaru Steam & Rail Museum (OS&RRS) in exchange for two diesel locomotives being loaned to the freezing works.
In 2000 the locomotive was acquired by the OS&RRS at Oamaru.
In 2007 the locomotive was taken out of service for its ten-year overhaul. The boiler was repaired at Scott’s Engineering in Christchurch while the frame and other major parts were overhauled and reassembled on site. It returned to traffic in May 2013.
In October 2013 the locomotive was loaned for a period to the Ashburton Railway & Preservation Society for the Rail 150 celebrations at The Plains Vintage Railway & Historical Museum.
It has since returned to Oamaru and is used on passenger trains.
