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. 

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 NR locomotive entered service in October 1996.

The entire NR fleet was delivered in the original National Rail Livery in grey and marigold colours.

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 and were painted in their appropriate livery.

With Pacific National ownership changes, the original National Rail livery was replaced and repainted into Pacific National livery.

In June 2006, NR33 was involved in a level crossing incident and was written off and scrapped. Several others have been involved in accidents or fires but have been rebuilt and put back into service.

DCC with Sound and Light 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 to 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 Austrian's 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 and an 8 pin socket for DCC. The release included powered and non-powered models.

About the SDS Models NR Class

Late in 2019, SDS released its own NR Class model, which included further tooling improvements from the Austrains model and now included a 21 pin socket for DCC.

For the Austrains/SDS NR Class installation, we recommend the ESU LokSound 5 (Sound) with our remastered Custom Sound Project for the NR Class or the LokPilot 5 (No Sound) for those not wishing sound

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 individual DCC control to provide more prototypical lighting operation when running your NR Class model.

For early production run models of the NR Class, that have 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 very basic sound

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 hard-working loaded 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, so this can simulate a hard-working locomotive. This exciting feature gives the operator the ability to have the loco crawling in notch 8 or coasting at 100 km/h along the track. Release the Drive Hold function button, and you simply go back to throttle-controlled speed, motion and sound. 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 sound or sound from other providers will not stop your loco at speed step 0 with the drive hold switched on, which can damage your model because you ran into something.

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 rolling 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, the sound will return to the speed that's 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. The brake can also be used while driving to slow the locomotive up.

Working Dynamic Brake

Apply the Dynamic Brakes and the Prime Mover will wind down to idle and slow up then 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 return to it's notched speed and the fans will turn off.

Brake Squeal on Deceleration

Activate this function and when you reduce the throttle speed, your locomotive will begin braking and slow up quicker as you continue to lower the throttle speed, and you will hear the squeal of the brakes. Accelerating will release the brakes.

Random Start-up Sequences with Move Off and Stopping Sounds

Now, with random start-up sequences, 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.

Remastered Horn Sounds

A new remastered Australian Kockum Sonics 5 Chime playable and short blast horn.

Random Sounds

While the factory fitted sound will only offer you 1-2 random sounds, DCC Solutions will have up to 10 random sounds that will play when either the loco is stopping or moving, to create even more realism to running your model.

Manual Notching

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