The Commonwealth Railways NC class consisted of two diesel-hydraulic locomotives built by Clyde Engineering, Granville, New South Wales in 1956.

Clyde Engineering advertised the DH series as a general purpose locomotive, mainly for light railways and sugar cane service.

[1] A single General Motors 6/110 two stroke diesel engine provided power through an Allison CRT5630 hydraulic transmission to mechanically coupled wheels.

The Lakewood Firewood Company (LFC) provided timber to the various mines in the "Golden Mile" region of Kalgoorlie, Western Australia.

The need to maintain a narrow gauge yard shunter at Port Augusta had diminished with the closure of the Central Australia Railway in 1980.

While assisting with the recovery of the society's steam locomotive W901, which had derailed in Eurelia yard in early 1988, the NC1's rear drive assembly seized up.

It was repainted in LFC colours and in November 1982 was trucked to Port Lincoln to replace steam locomotive Yx141 as a playground fixture in Hermitage Park.

[10] During 2008, the Port Lincoln Council undertook work to enclose the cab and tidy the body shell for safety purposes.
