Statement of significance:

Diesel-Electric Locomotive 4306 has heritage significance as it illustrates the tentative steps taken by the NSWGR to develop a standard diesel-electric locomotive for mainline service in the mid-1950s, and with the local construction of modern diesel traction for the domestic market. Locally built by Goninan and Company from imported components, 4306 has technical significance, and embodies the features of the subsequent 44 class which became the standard (6 traction motors, 4 cycle engine and a full-width cab behind a streamlined nose). The class is significant as it improved dramatically the conditions under which operations staff on the Railways worked. The locomotive is historically significant both as the last of the class to enter service, and as the last to be withdrawn. It is aesthetically significant as its streamlined shape demonstrates the modernism of the American outline of diesel locomotive consistent with the new generation of diesel-electric power, and has technical significance with Locomotive 4306 being the last new locomotive in the world to be placed in service with the ALCo 244 Series engine. Locomotive 4306 is considered rare as the only surviving member of its class.

Description

Designer/Maker: A. Goninan and Company; Australian Electrical Industries and others
Builder/Maker: A.Goninan and Company, Broadmeadow, NSW
Construction years: 1956-1956
Physical description: EXTERNAL
Locomotive 4306 is a Co-Co diesel-electric of car-body design with a full-width cab and streamlined nose. The locomotive is painted overall Indian red, with yellow stripes, lined in red and black bogies. The locomotive is built around a rigid plate frame with both sides of the locomotive body being integral with the external structure and forming a monolithic shell. This is continuously welded and lacks any projections. A full width cab is fitted at the No. 1 end, behind a streamlined but nevertheless boxy nose. A transition coupling is fitted along with buffers below the front end, which displays a twin-beam headlamp and two illuminated road number boxes, marker lamps and a cluster of multi-chime air horns.

MECHANICAL
The locomotive is powered by a single 12 cylinder, turbo-charged, 4 cycle, ā€˜Vā€™ formation, trunk piston, compression ignition oil engine, supplied by the American Locomotive Company (ALCo). The prime mover drives a 1600hp General Electric (GE) generator, coupled by switchgear to six traction motors.

History

Historical notes: Locomotive 4306 was ordered in June 1954 as part of a class of six. It was built by A. Goninan and Company of Broadmeadow near Newcastle as works number 16, with components from a number of suppliers. The main engine was supplied by American Locomotive Company (ALCo), the electrical equipment by General Electric (GE) and Australian Electrical Industries (AEI). The class was ordered in small numbers simultaneously with a similar sized order placed with Clyde Engineering for a General Motors outline diesel-electric. In this way the two orders can be seen as prototypical examples of contemporary diesel-electric locomotive technology. The 43 class itself is noted as being based upon an experimental GE locomotive. Locomotive 4306 was the last to enter service being placed in traffic in June 1957. The class was rostered on passenger workings, initially on the central west line. Following electrification to Lithgow in 1957, the class was transferred to service on the North Coast line and the main north, working from Broadmeadow with express freight services. Being a member of a small class, withdrawals took place quite early with number starting to dwindle in the mid-1970s. The last member of the class in service was 4306, being withdrawn in October 1979.

Following withdrawal, this engine was subsequently transferred to the custodianship of the New South Wales Rail Transport Museum. It was originally obtained as a source of spares to enable locomotive 4001 to be restored to operating condition, but during the early 1980s it was decided that 4306 should stand as a significant historical exhibit in its own right. To this end, the locomotive was restored to the stage where the body repairs were completed, all fittings made operational, and the engine repaired, started and checked. State Rail then undertook to complete the restoration and commissioning as part of the 140th Railway Celebrations in 1995.

Assessment of significance

SHR Criteria a)
[Historical significance]
Diesel-Electric Locomotive 4306 has historical significance. It is significant as part of a class of six locomotives built by A. Goninan and Company of Broadmeadow with components from a number of suppliers. The locomotive is significant both as the last of the class to enter service, and as the last to be withdrawn. It is associated with the tentative steps taken by the NSWGR to develop a standard diesel-electric locomotive for mainline service, and with the local construction of modern diesel traction for the domestic market.
SHR Criteria b)
[Associative significance]
Based on current knowledge, Diesel-Electric Locomotive 4306 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-Electric Locomotive 4306 has a high level of aesthetic significance. Its streamlined shape demonstrates the modernism of the American outline of diesel locomotive consistent with the new generation of diesel-electric power. The 43 class itself is noted as being based upon an experimental GE locomotive.

Diesel-Electric Locomotive 4306 has technical significance. It demonstrates an early attempt at local construction of a diesel-electric locomotive, with components from a number of suppliers. The main engine was supplied by American Locomotive Company (ALCo), the electrical equipment by General Electric (GE) and Australian Electrical Industries (AEI). Locomotive 4306 was the last new locomotive in the world to be placed in service with the ALCo 244 Series engine.
SHR Criteria d)
[Social significance]
The Diesel-Electric Locomotive 4306 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-Electric Locomotive 4306 has a high level of research significance. The locomotive has the potential to reveal information regarding an early attempt at local construction of a contemporary diesel-electric locomotive. The locomotive has significant research potential as it remains in almost unaltered condition from the day it was built.
SHR Criteria f)
[Rarity]
Diesel-Electric Locomotive 4306 has rarity significance. The locomotive is the only surviving member of a small class of early diesel-electric locomotives made locally using components from a number of manufacturers. Locomotive 4306 is also considered rare as the last new locomotive in the world to be placed in service with the ALCo 244 Series engine.
SHR Criteria g)
[Representativeness]
Diesel-Electric Locomotive 4306 is an excellent representative example of a prototypical mainline diesel-electric locomotive. It represents a diesel-electric engine from the first period of mainline diesel motive power, and also demonstrates the progression in the ALCo/GE partnership which was immediately followed by the introduction of the 44 Class. The technical and physical lineage is most evident when both classes of locomotives are studied together.
Integrity/Intactness: Diesel-Electric Locomotive 4306 retains a high level of integrity and intactness. The locomotive is complete, intact and in good operational condition, and with only minor exceptions, the locomotive displays the original condition of the class as introduced.
