Lachlan Valley Railway Society

The Lachlan Valley Railway Society is an Australian rail preservation society. It was established in 1974 to preserve and operate former NSW Government Railways locomotives and rolling stock.

It operates regular heritage train tours to a variety of locations across New South Wales.. The Lachlan Valley Railway was formed in 1974 initially to preserve locomotive 5917 and four carriages. It soon acquired other locomotives and formed a relationship with the Lachlan Vintage Village, Forbes. It then operated rail tours, including an interstate tours from Parkes to Peterborough in August 1976 with 5917.

At that stage, rolling stock was stabled at Parkes locomotive depot.. On 18 June 1977, the society moved its base to the 1923-built Cowra roundhouse. Initially allocated a couple of roads, in 1985 it took over the entire facility when the State Rail Authority vacated it.
