The Society's primary aim is to collect, preserve and operate a representative fleet of New South Wales Government Railways rail motors.

Each of these organisations purchased rail motors when they were offered for sale by the SRA and these were pooled to form the nucleus of the Society's fleet.

[2][3] The Rail Motor Society is run entirely by volunteers and funds its day-to-day activities, restorations and construction programs from the proceeds of its heritage train operations and donations from the public.

[8] In August 1986, HPC 402 was leased back to the State Rail Authority and after an overhaul used as a radio system test unit operating across NSW.

[2] It has continued to see regular main line use, often being hired by rail network owners for radio testing and for infrastructure and executive inspections.

The site houses the Society's rail motor fleet, a large three-road storage shed, maintenance facilities and the old station Master's cottage.

During 2020, the Depot site was increased in size with the inclusion of the abandoned ARTC siding located in the railway corridor adjacent to the eastern boundary.

The Society's own rolling stock collection – eleven of the current fourteen vehicles – was listed on the New South Wales State Heritage Register on 17 August 2001.
