About the 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 easily 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.

For this installation we recommend the ESU LokSound V4.0 (Sound) with our Custom Sound Project for the 422 Class or the LokPilot V4.0 (No Sound) for those not wishing sound.  We offer several different 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.

Here at DCC Solutions we offer a light modification for the 422 Class by upgrading the ESU 21 Pin decoder from 4 to 6 light outputs to separate the headlights, white markers and red marker lights for a more prototypical operation . Each pair of front and rear marker lights can be controlled individually so when the locomotive is standing in a siding or shunting it can have both front and rear red markers on at the same time as per NSWGR practice.Also you can have no rear markers on when pulling a load or simply just have the front white markers switched on. The front and rear headlights operate directionally and have a Low Beam/High Beam function.

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

For a Standard Light Modification we can separate the lights as follows:

1) Headlights - directional with 1 function button
2) Marker Lights - directional with 1 function button
3) Front Headlight - on/off with 1 function button

4) Front White Markers - on/off with 1 function button

5) Front Red Markers - on/off with 1 function button

6) Rear White Markers - on/off with 1 function button

7) Rear Red Markers - on/off with 1 function button

With our light modifications you can operate the lights on your model locomotive closer to the real thing! 
The DCC Solutions NSW 422 Class Custom Sound Project - EMD 16-645E Blower
is packed with sounds and features not found on other Sound Decoders
Our Custom 422 Class Sound Project now includes these new 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

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 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 motor 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.

Remastered Horn Sounds

A new remastered playable and short blast NSW RVB Hurricane 5 Chime Horn.

Coupling and Release with Shunting Mode
Activate coupling or release and your loco will automatically reduce it's speed to allow for 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.
And includes all these great features to make your Auscision 422 Class drive and sound impressive.
