The station building was constructed under the direction of John Whitton, Chief Engineer of the New South Wales Government Railways.

[1] A good example of a Victorian Italianate Renaissance style railway station that has an important relationship in the urban sense to the other major buildings of the township.

Together with the large hotels and other buildings nearby, the station plays an important role in creating the historic qualities of central Junee.

[1] The Station complex (in a 1944 photograph) included a garden room developed in the spaces between railway structures and buildings.

Windows / translucent sheeting is provided in sections of the rear or outer wall to assist with natural lighting.

[1] Apart from some minor deterioration and alterations carried out as the form of motive power changed, and the local heritage group occupied the premises, the building and other equipment is in reasonably good condition, both internally and externally.

Even though its original purpose (the servicing of steam locomotives) has been altered to suit newer motive power, with a subsequent change to work methods and equipment, the integrity of the roundhouse has been retained.

[1] Internally, the building retains a high degree of integrity due to the retention of original construction features and details.

[1] Many major components of important railway centres and work precincts have been demolished or otherwise removed or substantially modified and as a consequence, their past use can no longer be shown.

The depot comprised a roundhouse, large elevated coal bunker (for fuelling steam locomotives), boiler wash-out plant, ash handling arrangements, large and modern machine shop and a substantial amount of equipment essential for the rapid and efficient servicing and repair of the steam locomotives working in the district.

[1] Deleted items include the coal bunker, de-ashing arrangement, hot water boiler wash-out plant and a number of small buildings.

[1] Junee railway station was listed on the New South Wales State Heritage Register on 2 April 1999 having satisfied the following criteria.

[1] The place is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in New South Wales.

[1] The roundhouse, turntable and other structures which comprise Junee locomotive depot are socially significant because they are excellent representations of a source of much employment in the southern highlands region of the state.

[1] The place has potential to yield information that will contribute to an understanding of the cultural or natural history of New South Wales.

The roundhouse and other equipment were essential for these intense rail activities, involving passenger and goods, in an age when trains were the principal means of transport for the population.

[1] The items are technically and research significant because the roundhouse and its equipment are the remnants of a past era, located in an area of the state where railway played so much a part in development and essential transport, both interstate and intrastate.

[1] The place possesses uncommon, rare or endangered aspects of the cultural or natural history of New South Wales.

Steam locomotives were the principal form of railway motive power in New South Wales for approximately 110 years (1855–1965).

As such, steam locomotive servicing facilities incorporating engine sheds or roundhouse were established at approximately 150 sites in the state.

It is also estimated that 120 straight engine sheds and 25 roundhouses were also built, all there buildings being part of statewide locomotive servicing arrangements.

[1] There were differences in design of roundhouse buildings, mainly associated with roof shape, numbers of roads enclosed, location of windows and construction materials.
