National Rail NR class
|National Rail NR class|
The NR class are a class of Australian diesel locomotive built by A Goninan & Co for National Rail between 1996 and 1998. They are currently operated by Pacific National. The QR National 5000 (and 5020) class locomotives, and all the C44aci model locomotives build by UGL Rail at Broadmeadow adopted the design from the NR Class, but with a variety of features to set them apart from each other and the NR Class locomotives.
Upon commencing operations in April 1993 the National Rail inherited a diverse collection of rolling stock to operate interstate freight operations in Australia. The fleet included locomotives of mixed age and power leased from FreightCorp, V/Line and Australian National.
In September 1995 A Goninan & Co were awarded a contract for 120 locomotives from National Rail which were built at their Broadmeadow (NR1-NR60) and Bassendean (NR61-NR120) factories. The frames were built at Hexham and the bogies at Goninan's Landsdowne Engineering subsidiary in Taree.
The first locomotive to be completed was NR61 which performed its first trial on 18 September 1996 between Midland and Jumpakine. The first Broadmeadow built unit first ran on 23 September 1996. The first units were delivered without National Rail branding or logos, but later units were delivered in full livery. Testing of the units was carried out on the NSW Main Northern line between Werris Creek and Maitland using ballast wagons and 442 class locomotives in dynamic braking mode as dynamic loads. Each locomotive was required to accumulate 10,000 km of trouble free running before acceptance. In February 1998 Broadmeadow delivered the last NR class.
With the arrival of the class, National Rail was able to return leased units to their owners, including 422, 80, 81, and 82 class locomotives to FreightCorp, and 442s and 48s class locomotives to Silverton Rail.
The V/Line C class (which were owned by National Rail) and relatively new EL class were withdrawn. Once all 120 units were delivered, National Rail retained the AN, BL and DL class locomotives, along with thirteen 81 class and several hired G class. The new locomotives were placed on time sensitive trains first.
When first delivered, the NR class were banned from running in New South Wales by the Environment Protection Authority due to excessive noise when under dynamic braking but the ban was lifted after further testing. The class could also not lead on the Victorian standard gauge network due to the lack of suitable radio equipment. In later years NR76 to NR98 were provided with V/Line Section Authority System equipment to work the Western standard gauge line, while NR1 to NR13 and NR61 to NR72 were fitted with V/Line radios to operate on the Victorian North East line.
Great Southern Rail contracted National Rail to haul its services, the first train running with NR77 on 1 November 1997. All were included in the sale of National Rail to Pacific National in February 2002.
NR3 was involved in an accident at Robertson that killed two crew members, it was rebuilt as NR121.
In June 2006 NR33 was involved in level crossing incident, being the third locomotive on a Melbourne to Adelaide freight service, behind DL40 and NR52. It was subsequently written off and scrapped.
On 30 January 2009 train 5PS6 derailed on a washaway near Golden Ridge, just east of Kalgoorlie in Western Australia. Locomotives NR35 and NR51 finished up on their sides, badly damaged, and spent several years out of service before the decision was made to repair them. <https://www.atsb.gov.au/media/1521123/ro2009003.pdf>
On 3 April 2016 NR8 was involved in a fire at Cardiff NSW. The locomotive was rebuilt during 2016. NRs 48 and 81 had suffered similar fires several years earlier, both also being repaired but without the Pacific National signage on their hood sides.
On 21 April 2016, 3MP5 a Melbourne to Perth intermodal freighter derailed near Rawlinna in Western Australia. The two locomotives, NR34 and NR50, were badly damaged, but NR34 has been rebuilt and returned to service in late 2016. NR50 has been rebuilt with its last photographed sighting being at Millswood, South Australia on August 24, 2017 <https://www.atsb.gov.au/publications/investigation_reports/2016/rair/ro-2016-005/>
The NR Class introduced many new features. These were the first locomotives in Australia to have "variable horsepower", which meant that the power output of the engine had three different settings, making the NR class the most fuel-efficient locomotives in Australia. They have GE 7FDL-16 engines, with power levels of 2,850 hp (2,130 kW), 3,560 hp (2,650 kW) or 4,020 hp (3,000 kW), mass of 132 t (130 long tons; 146 short tons), a Co-Co wheel arrangement and a maximum speed of 115 km/h (71 mph). In fact the "variable horsepower" feature (so-called) was little more than a talking point (selling point?) and something of a furphy as far as being a valid feature went. Rather than going through the complicated process on the cab DID panel to configure the locomotive for a particular "variable power" configuration, precisely the same outcomes could be achieved simply by the driver voluntarily limiting operation to throttle positions 7 (to produce 3,560 hp or 2,650 kW operation) or 6 (for 2,850 hp or 2,130 kW operation).
The NR Class cab was designed taking into consideration the results of an extended consultative process with the end users. This has resulted in a cab that has been well accepted. The layout of the control stand evolved from a British Rail Class 60 cab, and is substantially different from the more common AAR type I (stand) and Type II (desk) cabs.
The design is a long hood unit locomotive, with only one cab but two separate sets of controls, which allow it be driven either "A" or "B" end leading. This locomotive had to pass all tests, such as being able to shunt if required, drive "long end leading" if needed, and allow drivers to do checks on fuel, brakes, and sand. Despite the twin controls, operation of the class "B" end leading is avoided, with single NR classes being turned on turntables to ensure they face the correct way.

Many locomotives have been named, the first being done on delivery. They were done at operational convenience rather than in groups of numbers. Names include cities and suburbs served by National Rail, in addition to their depots and maintenance centres. The special livered locomotives were given related names. It had been intended to name all locomotives, but by February 2000 only 70 had been named, a number not much larger today.
With Pacific National ownership further changes were made, the Pacific National decals placed over the side air deflectors replacing the National Rail signage. From 2006 the National Rail diamonds on the side and ends of the locomotives were removed or painted over. Most have now been repainted into Pacific National livery.
Some have been repainted into special liveries:
- NR74, NR75 & NR109 in red The Ghan livery
- NR25, 26, 27 & 28 in blue & yellow Indian Pacific livery. NR26 has been recently painted into the Mark 4 livery with white text on the side.
- NR84 & NR85 in 2008 in the ill-fated green & white The Southern Spirit livery
- NR16 in 2009 in a promotional Rail Safety livery
There was a proposal in 2011 to repaint some locomotives into new passenger liveries, with two locomotives each for the Indian Pacific, the Ghan and the Overland. NR18 was repainted in 2011 using a yellow and grey variant of the Southern Spirit's green and white livery, and it was scheduled to be followed by NR76 in a new Ghan livery before the program was put on indefinite hold. The Ghan scheme was likely a further palette swap to red and orange, and marketing materials from the era imply that the Overland scheme might have been a blue version.

Models of the NR Class locomotive have been available since June 2000. Austrains used the engine as a way to open up the then-modern era as a practical option for modelling Australian railways, and to date it is one of the highest-selling models in the Australian model railway market. The units initially retailed at $229 each with minor increases to cover copyrighted logos. Austrains was not able to obtain permission to recreate the Indigenous liveries as applied to NR30 and NR52, so in the second run they released the two engines with their respective short-lived grey and black schemes, to provide an undercoat base and allow customers to apply those liveries themselves, either with paint or decals.
The model was significantly re-engineered following the sixth run, and re-released in September 2009 at a new retail price of $275 per unit. Engines of runs seven and above include speaker enclosures within the chassis, working marker and ditch lights (with a manual switch under the fuel tank) and a modified coupler attachment system with the coupler box opening filled in. Austrains was also involved in the production of non-motored NR class models in N scale, sold to guests on Great Southern Rail's services as souvenirs.
Austrains was sold to SDS Models in 2015, and the new owners announced that some older models would be re-released under the "Austrains Neo" brand. One of those releases included the NR class, using the most recent tooling but without the motor fitted, to keep the price down to $165 per unit and to allow modellers to run trains with more than one or two engines on the front, at a reasonable price. Early 2017 saw the announcement of a new run of powered units, ranging from $275 to $395 each.
Also in 2015, Auscision Models announced their intent to release a run of NR class locomotives, starting the design from scratch. These models are expected sometime during 2017.

In more recent times, Frateschi has released rough approximations of the NR class in Ghan and Indian Pacific liveries, as part of cheap starter sets including three passenger or freight carriages. These tend to retail for around $300.
