Statement of significance:

Steam Locomotive 2705 has heritage significance as one of a small class of non-standard locomotives, originally purchased by the Public Works Department of New South Wales to provide motive power for construction trains associated with the building of lines. After being transferred to the Railways Department in 1917, the class provided good service in mixed, stock and goods traffic until withdrawn in the late 1950s at the advent of the 48 class diesels. Locomotive 2705 is significant as one of the last of its class in service, and was retained as part of the engine pool for rostering on the ‘Vintage Train’ before being transferred to Thirlmere. It is aesthetically significant as an example of an English outline locomotive, particularly in its original form, which was quite unlike comparable NSWGR locomotives of the time. Once modified, it conformed closely to the usual NSWGR profile, with tall dome and chimney. It demonstrates an early use of Walschaerts valve gear on a revenue earning locomotive (in fact the first such use on the NSWGR). Steam Locomotive 2705 is rare as it is believed to be the sole surviving Hunslet-built tender engine, and is thus a unique survivor of this small class.

Description

Designer/Maker: Hunslet Engine Company, Leeds
Builder/Maker: Hunslet Engine Company, Leeds
Physical description: EXTERNAL
Locomotive 2705 is a two cylinder, non-condensing, saturated, coal-fired, 2-6-0 ‘ Mogul‘ type steam engine. It has small diameter wheels for goods working and a low running plate. The outside cylinders are fitted with overhead steam chests and slide valves set up for outside admission, these being operated by outside Walschaerts valve motion. The coupling rods are plain in section, but the connecting rods are fluted. The boiler has a Belpaire firebox, Ramsbottom pattern safety valves, turbo-generator, high dome, cast iron chimney and headlamp. It is fitted with an enclosed steel cab with large cutaway sides. The number is painted in white on the front buffer beam, and in cream on the cab sides and on the rear of the tender. It is fitted with a 3,650 gallon, eight-wheel, bogie tender of riveted construction from a T class locomotive. It is painted overall in lined green.

History

Historical notes: Locomotive 2705 was constructed by the Hunslet Engine Company, Leeds as works number 1115 in 1913. Built to the order of the Public Works Department of New South Wales, it entered service in 1914 having been allocated the PWD number 5. The class of 8 locomotives were ordered to provide motive power for construction trains associated with the building of lines, then the responsibility of the Public Works Department. Published sources suggest that these projects included the lines from Coffs Harbour to Glenreagh and thence to Dorrigo, also Humula to Tumbarumba.

After responsibility for new lines was transferred to the Railways Department in 1917, the engines associated with these projects also came under Railways control. At this time they were known as the G class and renumbered into capital stock, number 5 being allocated the road number 1208. Their continuing career in construction work was short-lived, the class being transferred to general service soon after the transfer. The class was trialled in a number of applications, the most suitable being branch line work from the depot at Narrabri, which was devoid of sharp radius curves, always a problem for this class. The class was renumbered in 1924 as the Z27 class, 1208 being allocated 2705. Following further service the class was rebuilt with from 1930 to 1942 with standard Z25 class boilers, domes and chimneys, thus changing their outline and appearance. They provided good service in mixed, stock and goods traffic until withdrawn in the late 1950s at the advent of the 48 class diesels. Locomotive 2705 was one of the last in service, being retained as part of the engine pool for rostering on ‘Vintage Train’ running. The locomotive was subsequently transferred to the New South Wales Rail Transport Museum arriving at Thirlmere in 1975. It was returned to steam in 1995, following a cosmetic restoration, and was until recently the only steamable locomotive in the RTM.

Assessment of significance

SHR Criteria a)
[Historical significance]
Steam Locomotive 2705 has historical significance as it was built to the order of the Public Works Department of New South Wales to provide motive power for construction trains associated with the building of lines. After being transferred to the Railways Department in 1917, the class provided good service in mixed, stock and goods traffic, particularly in the Narrabri area where it and the other members of the class saw use for many years until withdrawn in the late 1950s at the advent of the 48 class diesels. Locomotive 2705 is significant as one of the last of its class in service, and was retained as part of the engine pool for rostering on the ‘Vintage Train’ before being transferred to Thirlmere.
SHR Criteria b)
[Associative significance]
Based on current knowledge, the carriage is not known to have any special associations with people or events of significance in a local or state context. It does not have significance under this criterion.
SHR Criteria c)
[Aesthetic significance]
Steam Locomotive 2705 has a high level of aesthetic significance. It is aesthetically significant as an example of an English outline locomotive, particularly in its original form, which was quite unlike comparable NSWGR locomotives of the time. Once modified, it conformed closely to the usual NSWGR profile, with tall dome and chimney. Only the style of the cab cut-away and the outside Walschaerts valve gear and steam chests differentiated it appreciably from the (Z) 25 Class. The transition in appearance, brought about through standardisation, is interesting in itself, and adds to the aesthetic significance of the class.

Steam Locomotive 2705 has technical significance as it incorporates an early use of Walschaerts valve gear on a revenue earning locomotive (in fact the first such use on the NSWGR). As rebuilt from 1930, the class also demonstrates the NSWGR policy of standardisation.
SHR Criteria d)
[Social significance]
The Locomotive, Steam 2705 is likely to have a degree of social value for the community-based associations who have demonstrated an ongoing interest in its conservation and management. This item may also have a degree of social significance to a broader section of the community linked to its historic, aesthetic and associative values.
SHR Criteria e)
[Research potential]
Steam Locomotive 2705 has research significance with the potential to reveal important information regarding the continual adaptation of British manufactured rolling stock to suit the changing needs and requirements of the NSW railway system, and the resultant NSWGR attempts at a policy of standardisation.
SHR Criteria f)
[Rarity]
Steam Locomotive 2705 is rare as it is believed to be the sole surviving Hunslet-built tender engine, and is thus a unique survivor of this small class.
SHR Criteria g)
[Representativeness]
Steam Locomotive 2705 is an excellent representative example of a large group of NSWGR 2-6-0 locomotives, including the 24 and 25 classes, but with the difference of Walschaert valve gear.
Integrity/Intactness: Steam Locomotive 2705 retains a moderate level of integrity and intactness. It is complete and intact in modified configuration, though painted in a livery it never carried in service.
