Statement of significance:

Locomotive 4490 has heritage significance as one of the 44 class of locomotives, which defined mainline diesel power on the New South Wales Government Railways for over 25 years. Streamlined, with a four-cycle engine, cabs at both ends with all axles powered, these features were embodied in the design that became the standard. Built in unprecedented numbers for diesel locomotive construction, the 44 class contract demonstrated the maturity and capability of local manufacturer A.E.Goodwin to successfully enter this specialised industry sector. The Goodwin-ALCo 44 class ushered in the era of diesel-electric motive power in New South Wales, of which 4490 was one of the last built. Locomotive 4490 is part of the last batch of 40 units of this class that were built and which differed from earlier deliveries of the 44 Class, and which came to define the more 'typical' 44 class layout.

Description

Designer/Maker: American Locomotive Company, Schenectady, New York
Builder/Maker: A.E.Goodwin Ltd, St Marys New South Wales
Construction years: 1967-
Physical description: EXTERNAL
Locomotive 4490 is a Co-Co diesel-electric of car-body design with a full-width cab and streamlined nose. The locomotive is built around a rigid plate frame with the sides of the locomotive body being fabricated with framework and plating. A full width cab is fitted at the No. 1 end, behind a streamlined yet blunt nose. A transition coupling is fitted along with a buffing plate 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. A cab is provided at the No.2 end of the locomotive, the cab being flat in profile with a gangway door with a headlamp and marker lights. The locomotive is painted overall Indian red, with yellow stripes, lined in red and black bogies. Reflective markings have been added. Staff exchanger boxes have been plated over for an unknown reason.

MECHANICAL
It is powered by a single 12 cylinder, turbo-charged, 4 cycle, ‘V’ formation, trunk piston, compression ignition oil engine, supplied by the American Locomotive Company (ALCo). The prime mover drives an 1800hp General Electric (GE) generator, coupled by switchgear to six traction motors. The locomotive is fitted with 3PE 6-wheel Goodwin-Alco World Bogies with a central electric motor on each axle.
Physical condition and/or
Archaeological potential:
Operational Status: Operational
General Condition: Good Condition
External Condition: Good Condition
Internal Condition: Good Condition

EXTERNAL CONDITION
The locomotive is complete and in full operating condition. A number of material changes have been made to the machinery in the locomotive to improve performance for charter train working. The paintwork of the locomotive is in good condition.

INTERNAL CONDITION
The cabin of the locomotive is in good condition. The engine room was not able to be inspected but is assumed to be in good condition given the fact that the locomotive is maintained in operational condition.
Date condition updated:11 Nov 09
Modifications and dates: December 1964 - ordered by the New South Wales Government Railways with A.E.Goodwin of St Marys
July 1967 - completed and handed over
July 1994 - condemned and was subsequently transferred to the New South Wales Rail Transport Museum where it was repainted to its original livery for use as part of their charter fleet. The livery has since been modified to a version of the original 4401 livery.
Unknown: Traction motors were replaced with altered pinion gearing for better performance. Vigilance equipment was fitted to the entire class.
Further information: The original generator, excitation, and traction motors were replaced with those from scrapped locomotives from the series 4411-4460 being of GE manufacturer. These were deemed to be more reliable and gave a higher level of performance compared with the original AEI equipment. 4490 has been modified by the RTM to plate over the staff exchanger boxes, and apply a version of the 4401 colour scheme.
Current use: NSW Government Railways Collection
Former use: 44 Class Diesel Electric Locomotive

History

Historical notes: Locomotive 4490 is one of 100 locomotives that made up the 44 Class, and was ordered by the New South Wales Government Railways (NSWGR) in December 1964, part of the last batch of 40 units, the first small batch of ten being ordered in March 1957. The order was placed with A.E.Goodwin of St Marys, Locomotive 4490 being completed and formerly handed over in July 1967. Based upon ALCo’s 1800hp ‘World Model’ (DL500B), the class represented a standardisation of design for mainline diesel-electric power. The class was immediately utilised on a number of express passenger workings, including the Melbourne Limited, Inter-Capital Daylight and Brisbane Expresses. They were also used on the Southern Aurora and later the Indian Pacific following its inauguration in 1970. Fast freight workings were another duty for the class. Their lengthy service life was characterised by trouble-free running, popularity with crews, unprecedented working intensity and increasing orders. As newer diesels were delivered, withdrawals commenced in the late 1980s until all remaining units including 4490 were stopped in July 1994.

Locomotive 4490 was subsequently transferred to the New South Wales Rail Transport Museum where it was repainted to its original livery for use as part of their charter fleet. The livery has since been modified to a version of the original 4401 livery.

Assessment of significance

SHR Criteria a)
[Historical significance]
Locomotive 4490 has a high level of historical significance. Locomotive 4403 is one of the 100 locomotives that make up the 44 class, the first mainline diesel-electric locomotive to be ordered in large numbers. It demonstrates the capacity of local manufacturers to build state-of-the-art rolling stock and the willingness of the NSWGR to embrace modernisation with the adoption of successful technology from overseas. The class has historical significance for its use on express passenger routes including the Melbourne Limited, Inter-Capital Daylight and Brisbane Expresses. They were also used on the Southern Aurora and later the Indian Pacific following its inauguration in 1970.
SHR Criteria b)
[Associative significance]
Based on current knowledge, Locomotive 4490 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]
Locomotive 4490 has a high level of aesthetic significance. Locomotive 4490 is significant as a member of this aesthetically important class of locomotive which features a double-cab (Co-Co) car-body design with a full-width cab and streamlined nose with a twin-beam headlamp. Working conditions for locomotive crew, operations and maintenance staff were materially changed for the better with the advent of this class.

Locomotive 4490 has a high level of technical significance. It demonstrates a state-of-the-art diesel-electric locomotive from the 1950s. Based upon ALCo’s 1800hp ‘World Model’ (DL500B), the class represented a standardisation of design for mainline diesel-electric power, with their lengthy service life characterised by trouble-free running, popularity with crews, unprecedented working intensity and increasing orders.
SHR Criteria d)
[Social significance]
The Locomotive 4490 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]
Locomotive 4490 has a high level of research significance. Locomotive 4490 is part of the last batch of 40 units of this class that were built and which differed from earlier deliveries of the 44 Class, and which came to define the more 'typical' 44 class layout.
SHR Criteria f)
[Rarity]
Locomotive 4490 has rarity value because it was one of the last of this important class to be built and to remain in service.
SHR Criteria g)
[Representativeness]
Locomotive 4490 is an excellent representative example of the first standard class of mainline diesel-electric locomotives introduced onto the NSWGR. Locomotives 4401 and 4403 are not totally representative of the 44-class however, as to accurately represent the class as a group of 100 locomotives then an example from the group 4411-4469 would be more representative. Because the NSW Government Railway Collection does not contain any locomotives from this group, then Locomotive 4490 as it was at the time of removal from service is thought to better represent the whole class, as it has been modified to carry the GE main generator and traction motors which were removed from scrapped locomotives in the series 4411-4460.
Integrity/Intactness: Locomotive 4490 retains a high level of integrity and intactness. It remains in substantially ex-service condition and is fully operational.
