About The NR Class

The NR class are a class of diesel locomotive built by A Goninan & Co for National Rail between 1996 and 1998. 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. 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. As part of its contract, A Goninan & Co was required to maintain the fleet.

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 442 and 48 class locomotives to Silverton Rail. 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.

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 and was written off and scrapped. On the 3rd of April 2016 NR8 was involved in a fire at Cardiff nsw the locomotive is currently in storage awaiting rebuild. On the 21st of April 2016 two locomotives NR 34 and NR 50 derailed and were badly damaged and have been written off as well as a large number of rolling stock.

While the NR Class was mainly used on freight services they also were used on Indian Pacific (NR25,26,27,28,18), The Ghan (NR74,75,109) and Southern Spirit (NR84,85) passenger services.

As of August 2016 of the 120 units built there are 116 still in service including NR121 (formerly NR3) which was rebuilt and put back into service.

NR8 is stored and awaiting a rebuild while NR33, NR34 add NR 50 have been scrapped.

DCC with Sound and Lighting Modifications

About the Austrains NR Class

In 2000, Austrains released the first NR Class which was a DC only model with incandescent light bulbs for the headlights. Several releases followed over the years and in 2009, Austrains released an improved production run included an 8 Pin socket for fitting a DCC decoder and for the first time LED lighting for the Headlights, Marker Lights and Ditch Lights. In the original factory setup, when operating in DC or DCC all the lights operate directional. Switches are included on the bottom of the fuel tank allowing you turn off the lights when running the locomotive.

About the SDS/Austrains NEO Models NR Class

In 2017, SDS Models took over production of the Austrians NR class and released the SDS/Austrains NEO branded version of the NR class.

The model features the current tooling from Austrains and includes operating headlights, marker and ditch lights and included Kadee couplers. The release included powered and non-powered models.

For the NR Class installation we recommend the ESU LokSound 5 (Sound) with our Custom Sound Project for the NR Class or the LokPilot V4.0 (No Sound) for those not wishing sound. We offer several options of DCC installations for this model to suit all budgets and can supply the decoders only for the DIY installers.

We have tweaked the motor control of the ESU decoder to provide super slow smooth speed which is perfect for shunting operations allowing the loco to move ever so slowly towards its rolling stock. Also, for those wanting the locomotive to move off slowly and build up speed like the prototype. You will be impressed with the smooth slow speed motor control.

                                We offer a light modification for this NR Class to separate the lights for a more prototypical operation.

For the later production run models of the NR Class which include LED lights we are able to separate the headlights, white markers, red markers and ditch lights for a more prototypical operation. The front and rear headlights operate directionally on/off. Each pair of front and rear white markers, front and rear red markers, front and rear ditch lights can be controlled individually using function buttons on your DCC controller.

With our light modifications you can operate the lights on your model locomotive closer to the real thing!

You can also still operate all the lights directional as the way the model was delivered.

For the early production run models of the NR Class which include incandescent light bulbs for the headlights we will replace these with LEDs.

The DCC Solutions NR Class Custom Sound Project

is packed with sounds and features not found on other sound decoders especially factory fitted sound.

Factory Fitted Sound only offers you the very basic sound for your model

So why not get fully featured sound from DCC Solutions

Our Custom Sound Project now includes these fantastic features:

Full Throttle – Drive Hold

This feature allows you to simulate a loaded or empty train by pressing the F1 function button. When the button is pressed, the motor will remain at a constant speed, while the sound can be controlled independently by adjusting the speed on the throttle. This exciting, new feature gives the operator the ability to have the train crawl in notch 8 or coast at 100 km/h. Release the Drive Hold function button and you simply go back to throttle-controlled speed and motion. Available only from DCC Solutions, our Drive Hold will stop your loco when you reduce the speed to zero even while the function is still active. Your ESU factory fitted or downloadable sound will not stop your loco at speed step 0 with the drive hold on.

Coasting on Demand

This feature allows you to enter coasting mode whenever you want with a press of a button. Often when coming to a stop, the throttle of a real locomotive is put into Idle and the locomotive coasts to a stop. Another situation that occurs is that once a train is up to speed when operating over the

NSW's countryside, the driver can coast to maintain a certain speed. By pressing the coast function button, the sound drops into coasting and remains there. Using the throttle speed control, you can now speed up or slow down the train with the sound remaining in coasting mode.

Press the function button to exit coasting and the sound will exit and return to whatever speed is set when exiting.

Working Brake

Press the Brake Function button and your locomotive will come to a stop at a much shorter distance than if you were to bring it to a stop by reducing the throttle speed. Release the brake and your locomotive will move off again or choose to have it remain stationary when the brake is released.

Working Dynamic Brake

Apply the Dynamic Brakes and the Prime Mover will wind down to idle while the Dynamic Fans engage to assist with cooling. Reduce the throttle and the decoder's dynamic braking logic will reduce your speed faster than normal. Disengage Dynamic Braking and the primer mover will returned to it's notched speed and the fans will turn off.

Random Start-up Sequences with Move Off and Stopping Sounds

Now with random start-up sequences including hot or cold engine starts your start up and shut down will not always sound the same.

As your locomotive begins to move off you will hear the sounds of brakes releasing with random speed activated wheel squeal, rail noises and other sounds. Some of these sounds are random or speed sensitive that will turn on/off automatically depending on your take off speed. When the locomotive comes to a stop you will hear the squeal of the brakes, air releases and then the compressor will cut in automatically to fill the reservoirs with air until full and will cut out.

Coupling and Release with Shunting Mode

Activate coupling or release and your loco will automatically reduce its speed to allow for a more realistic coupling or release operation. Once the operation is completed your loco will continue to run at slow speed for a few more seconds before returning to the speed set on your throttle.

Manual Notching

For those who really want to drive their train and manually control the notching rather than letting the decoder do it.

Random Sounds

At least 12 random sounds that will play when either the loco is stopped or moving to add to the realism.

Idle Modes

During the idle running, you can activate low idle mode while sitting stationary then return to normal idle at a press of a function button.

And includes all these great features to make your Austrains/SDS NR Class model drive and sound impressive.
