Auscision 422 Class Diesel Locomotive 

DCC Sound Installation with Light Modifications

Now available with our NEW Remastered Custom Sound Project

including "Full Throttle - Drive Hold" feature

About the NSW 422 Class

The 422 class are a class of diesel locomotives built by Clyde Engineering, Granville for the New South Wales Government Railways in 1969/70 with a total of only 20 units built and were fitted with an EMD 16-645E roots-blown engine. The delivery of 42201 in January 1969, marked the commencement of a new era of locomotive design in Australia with the first use of a non-streamlined, double-ended box cab full-car body arrangement. The 422 class were introduced into service on the Main South and Illawarra lines, where they would spend most of their New South Wales careers hauling passenger and freight services. Among the services they hauled were the Canberra Express, Intercapital Daylight, South Coast Daylight Express, Southern Aurora, Spirit of Progress and Sydney/Melbourne Express.


In late 1980, 42220 was rebuilt at the Clyde Engineering Rosewater SA plant. This locomotive was fitted with many upgraded features, including Super-Series wheel slip technology and an EMD AR16 alternator replacing the D32B generator that was fitted to the rest of the class. Whilst retaining its general shape, many body modifications were carried out. Clyde designated 42220 a model J26C-2SS, and it was the only 2000HP locomotive in the world to be fitted with Super-Series.


From 1982 they began to operate through to Melbourne. This ceased in February 1990 when non air-conditioned locomotives would no longer be accepted by Victorian drivers. From 1996 into 1997, the 20 class members were allocated to National Rail, pending delivery of its NR class locomotives.

DCC with Sound and Light Modifications

In February 2013, Auscision released the 422 Class Locomotive, which includes the 21 Pin MTC socket for fitting a DCC decoder and two speaker enclosures that are designed for 40 x 20 mm speakers. In the original factory setup, when operating in DC/DCC, all the lights operate directional.

In October 2019, released their second run of the 422 Class, which was the same as the 1st release but came with their Vandersound speaker enclosure with twin speakers. With the original factory setup, when operating in DC/DCC, all the lights operate directional.


For this DCC installation, we recommend the ESU LokSound 5 (Sound) with our remastered Custom Sound Project for the NSW 422 Class or the LokPilot 5 (No Sound) for those not wishing sound.


We offer a light modification for the Auscision 422 Class to separate the lights for a more prototypical operation

Standard factory lighting in the model has all lights “ON” in the direction of travel, requiring just 2 function lighting outputs in DCC.

Upgraded from the factory standard 2 to a possible 8 Function lighting outputs with the DCC Solutions light modification where we will separate the headlights, numberboards, white markers and red markers lights for individual DCC control to provide more prototypical lighting operation when running your Auscision 422 Class model. Directional light control will still be available.


Unlike ESU/Auscision factory sound which uses 2 sound slots to operate the lights, our light modification does not use any sound slots for lighting, so all the 10 sound processing channels are available to play sounds when using all the lighting, so you will get the full sound experience all the time.

The DCC Solutions NSW 422 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 very basic sound and features

So why not get fully featured sound from DCC Solutions

Our Custom Sound Project now includes these fantastic features:

Custom Built NSW 422 Class Sound Project

This is not just a basic factory sound project but a completely custom-built sound project by DCC Solutions that contains recorded sounds with customised sound programming plus extra features that will make your NSW 422 Class Auscision model a uniquely, impressive driving and sounding loco that will turn heads!

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

New remastered NSW RVB Hurricane 5 Chime Series 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.
