Statement of significance:

Diesel Locomotive 4807 has heritage significance as it represents an important class of diesel-electric locomotives which dramatically changed the carriage of passengers and freight on the New South Wales Government Railways. Capitalising on an unprecedented availability for a locomotive of this power, the 48 class returned extraordinary reliability and effectiveness, becoming the standard for secondary line operations with increasing use on the mainline. This locomotive is an example of a class designed with a light axle load and used on every line in NSW. It is significant as the only diesel locomotive class to work on all main line gauges.

Description

Designer/Maker: American Locomotive Company (ALCo), Schenectady, New York
Builder/Maker: A.E.Goodwin, St.Marys, New South Wales
Physical description: EXTERNAL
Locomotive 4807 is a Co-Co diesel-electric of hooded design with a full-width cab, displaced longitudinally off-centre. The locomotive is built around a rigid plate frame with the locomotive body being inset from each side. Access to the main engine and other machinery is through hinged panels on either side. A full width cab is fitted which is displaced off-centre to No.1 end. A transition coupling and buffing plate is fitted to each end which displays a twin-beam headlamp and two illuminated road number boxes and marker lamps. There is a cluster of multi-chime air horns above the cab. The locomotive is painted in the original livery of Indian Red and Chrome Yellow.

INTERNAL
The locomotive is powered by a single 6 cylinder, supercharged, 4 cycle, ‘in-line’, trunk piston, compression ignition oil engine, supplied by General Electric. The prime mover drives a 950hp generator, coupled by switchgear to six traction motors.

History

Historical notes: Locomotive 4807 was built by A.E.Goodwin under license from the American Locomotive Company (ALCo) of Schenectady, New York, to the order of the New South Wales Government Railways. As part of initial order of 20 locomotives, it represented the start of a major exercise to provide diesel-electric motive power to branch lines and country and regional depots. Following letting of the contract in March 1958, 4807 was delivered and in service by November 1959. The first 20 were allocated to the north western region, split between Werris Creek and Casino, running to Moree and Murwillumbah respectively. Shortly after a further order was placed with Goodwins for 10 more units with subsequent orders building the class numbers up to 45 by 1963. These locomotives were to be known as the Mk 1 units of the class. The class, when allocated to regional areas displaced steam traction, the practice accelerating during the 1960s as additional orders were placed, with the 165 and final locomotive entering service in October 1970. The 48 class has operated on every branch line on the system and were a powerful vindication of their initial choice and builders. The early members of the class were stored in the early 1990s only to be re-activated during the wheat harvest of 1996. Many of these were subsequently sold, yet many of the Mk2 units remain in service.

Locomotive 4807 was officially withdrawn in September 1994 though it was subsequently returned to service before being transferred to the Regional Heritage Transport Association (RHTA) and placed on static display at the Junee Roundhouse, still in its Freight Corp livery and branding.

On 26 May 2002 the locomotive was delivered to Canberra to the ACT Division of the Australian Railway Historical Society. After being out of service for seven years, the locomotive underwent a minor restoration before being returned to service in 2003. The bodywork was in moderate condition and the Society restored the locomotive livery back to its "as built" colours of Indian red and chrome yellow. The locomotive underwent a major overhaul at Junee in 2008 and has since returned to service as the major operational diesel locomotive used by the ACT Division of the Australian Railway Historical Society.

Assessment of significance

SHR Criteria a)
[Historical significance]
Diesel Locomotive 4807 has historical significance. It is one of 165 48 class locomotives built for the NSW Railways, designed with a light axle load and was capable and did work every line in NSW. The class of locomotive is still being used for commercial operations and several (including 4803 and 4807) are preserved and used on heritage locomotive hauled trains.
SHR Criteria b)
[Associative significance]
Based on current knowledge, Diesel Locomotive 4807 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]
Diesel Locomotive 4807 has a high level of aesthetic significance. Its design is significant because it demonstrates along with the 45 and 47 classes an evolution in design for diesel locomotives for this period. The locomotive has a number of external design features which make it significantly different in the evolution of the development of locomotives in Australia. The locomotive has been restored to its original livery of Indian Red and Chrome Yellow.

Diesel Locomotive 4807 has a high level of technical significance. The 48-class locomotive is the most numerous class of diesel locomotive used in NSW. The class worked on every line due to its light axle load.
SHR Criteria d)
[Social significance]
The Diesel Locomotive 4807 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]
Diesel Locomotive 4807 has a moderate level of research significance. The locomotive has the potential to reveal information regarding the development of diesel locomotives in Australia.
SHR Criteria f)
[Rarity]
Diesel Locomotive 4807 does not have rarity significance. The 48-class locomotive is the most numerous class of diesel locomotive used in NSW, and the locomotive class is not considered rare.
SHR Criteria g)
[Representativeness]
Diesel Locomotive 4807 is representative of a 48-class locomotive, the most numerous diesel locomotive used in NSW with a total of 165 units eventually placed in service with the NSWGR as well as 44 being built for the South Australian Railways and another 3 for the Broken Hill based Silverton Tramway Company. This locomotive is representative of a first generation secondary line diesel-electric locomotive.
Integrity/Intactness: Diesel Locomotive 4807 retains a high level of integrity and intactness. The locomotive is intact and in its original livery is able to give rise to the above categories of significance.
