About the NSW 442 Class

The 442 class are a class of diesel-electric locomotives that were built for the New South Wales Government Railways between 1970 and 1973. A total of 40 locomotives were built by Alco's Australian licensee AE Goodwin and Comeng, Auburn. The 442 Class were used on both main freight and passenger service in NSW and when they entered private ownership they have operated across all of Australia. They were nicknamed Jumbos, due to their 1971 delivery coinciding with that of Qantas' first Boeing 747 aeroplanes. The 442 class are identical to the South Australian Railways 700 class locomotive.


The 442 class were built to replace the 1951 built 40 class locomotives. The first 442 was completed in October 1970 but was rejected due to rough riding concerns during testing. It took a further 5 months for changes to be made to the bogie design and it being passed for service. The first 442 finally began service on 29th March 1971 and operated mainline services across the state. In 1985, locos 44223 to 44227, 44229 and 44230 were fitted with V/Line radios to allow them to operate services through to Melbourne. This stopped in 1987 with those locos fitted being sent to Melbourne to have the equipment removed. By the end of their careers, all were based at Broadmeadow Locomotive Depot and mainly operated on the North Coast and Main North lines.


Following the delivery of new 82 and 90 class locomotives, most were withdrawn in 1994. In December 1994, nineteen were sold at auction to private operators. A locomotive shortage saw an additional six reinstated by FreightCorp in late 1995 and were used as shunters in Sydney, with the last of them withdrawn in March 1998. The only to be preserved was 44211 and is operational.

In 2001, five of the 442 class locos were overhauled and returned to service as the JL class. A further 12 were remanufactured and reclassified as the GL class between June 2003 and October 2004. The original Alco 12-251C engines and AEI generators were replaced with fully overhauled GE 7FDL-12 engines and alternators.

DCC with Sound and Light Modifications

In March 2019, Auscision released the 442 Class locomotive which includes a 21 Pin socket for fitting a DCC decoder plus a speaker enclosure that suits two DCC Solutions High Performance Dynamic "Thunder" Speakers (11 mm X 15 mm). There are micro switches under the model for turning lights on/off in DC. In standard DCC, all lights will operate directional.


For this DCC installation, we recommend the ESU LokSound 5 (Sound) with our remastered Custom Sound Project for the NSW 442 Class or the LokPilot 5 (No Sound) for those not wishing sound.

Our Custom Sound Project is NOT the Generic sound file from ESU and Auscision.....It's Better!

And it does contain prototypical recorded sounds.


We offer full individual light control for the Auscision 442 Class to separate the lights for a more prototypical operation

Our Custom NSW 442 Class Sound Project offers a light modification for this Auscision model to separate the headlights, numberboards, white markers and red markers lights for individual DCC control to provide more prototypical NSW Railways practice lighting operation when running your Auscision 442 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 442 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:

Two Custom Built NSW 442 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 442 Class Auscision model a uniquely, impressive driving and sounding loco that will turn heads! .... Why?

DCC Solutions has produced Two Custom Sound Projects for the 442 Class Locomotive

For the original 442 Class - Alco 12-251C.

For the rebirth GL Class - GE 12-7FDL

Now you can have the correct prime mover sound to suit both the original 442 or the remanufactured GL class models.

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.

Included are the remastered NSW Nathan P5 and M5 horns, as some 442 may have carried these horns at some stage of their service.

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.
