at
Newcastle preparing to head south with a
Newcastle Flyer special in 2007 The NSWRTM was established in October 1962 with 62 members. A survey of potential sites around Sydney found
Enfield Locomotive Depot to be the most suitable and in 1963 a successful submission was made to the Department of Railways. Under the arrangement the department would retain ownership of the locomotives and rolling stock and responsibility for their maintenance. As Enfield depot was still active, exhibits were sent to Enfield for storage but not able to be accessed. In 1967, the department made an area adjacent to
Petersham station available to the museum. The first locomotives outshopped were
3526 and
3609 painted blue and green respectively. In July 1969, the NSWRTM was able to move into Enfield Roundhouse Number 3 with all exhibits transferred by September. In 1970, the museum was able to relocate into the larger Roundhouse Number 1, allowing the majority of the collection to be stored undercover. In October 1972, the display at Enfield was officially opened by Commissioner for Railways, Neil McCusker. as a static exhibit circa 1991 The NSWRTM had always maintained a good relationship with the Department of Railways, but in October 1972 it was replaced by the
Public Transport Commission. The PTC under Commissioner
Philip Shirley decided it wanted all steam locomotives, including those owned by preservation organisations, off the network with
3820 operating the NSWRTM's last tour to
Taree in 1974. The PTC also decided it wanted nothing to do with maintaining the NSWRTM's collection and handed over the exhibits to the museum under a Deed of Gift. The NSWRTM opened at its current location in on 1 June 1976. Services on the loop line between Thirlmere and Buxton began on 13 June 1976. In 1993, the museum concluded a lease for the
Picton – Buxton railway line following its closure by the
State Rail Authority. The NSWRTM was removed as a board member of
3801 Limited in November 2006 after the 20-year lease of
3801 was not renewed. The locomotive was returned to the NSWRTM. ==Redevelopment==
