DCC Sound Installation with Light Modifications

Now available with our NEW Remastered Custom Sound Project

About the NSW 48 Class Locomotive

The 48 Class diesel-electric locomotives were built by A.E Goodwin, Auburn for the NSW Government Railways in four production batches (or mark versions) between September 1959 and October 1970. They were built under the ALCO DL531 model with the largest number of 165 units built for NSW, 44 units built for the South Australian Government Railways 830 Class which operated services throughout SA on the narrow, standard and broad gauge lines. A further 3 narrow gauge examples were purchased by Silverton Rail for use on the Silverton Tramway Line around Broken Hill.

There were four versions built for the NSWGR were:

  • Mark 1: 4801 – 4845 (September. 1959 to March 1962)
  • Mark 2: 4846 – 4885 (June 1964 to September 1965)
  • Mark 3: 4886 - 48125 (March 1966 to July 1968)
  • Mark 4: 48126 – 48165 (January 1969 to October 1970)

The NSWGR 48 Class was ordered to commence the conversion of branch lines to dieselisation and to see if branch line operating costs could be reduced. They became an immediate success, and by the early 1960's the heaviest trains in NSW were being hauled by multiply 48 class locomotives. They later went on to become the backbone of the NSW Fleet.

As well as branch lines, they operated both mainline and metropolitan services and were seen on every line in the state. Aside from a couple written off after accidents in the mid-1980s, withdrawals didn't commence until August 1994. Others have been withdrawn since and as at January 2014, 66 units still remained in service as an extremely simple and reliable locomotive capable of performing any duty. Of the other 99 units, 7 have been preserved, 29 stored, 63 scrapped.

DCC with Sound and Light Modifications

In June 2018, Auscision released their version of the 48 Class locomotive which includes a 21 Pin socket for fitting a DCC decoder plus a speaker enclosure that suits a 16x35 mm speaker. There are micro switches under the model for turning the lights on/off in DC.


For this DCC installation, we recommend the ESU LokSound 5 (Sound) with our remastered Custom Sound Project for the NSW 48 Class or the LokPilot 5 (No Sound) for those not wishing sound.


Prototypical light modification for this Auscision 48 Class to separate the lights

Our Custom NSW 48 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 NSWGR practice lighting operation when running your Auscision 48 Class model. Directional light control will still be available.

The DCC Solutions NSW 48 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 48 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 48 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.

Dynamic Brake Logic

There are no Dynamic Brakes on a 48 Class Locomotive, however we have included Dynamic Brake Logic in this sound project to allow your 48 Class loco to run in a trailing consist with other locos that may have Dynamic Brakes.

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 playable and short blast horn including NSWGR WABCo A/B Series, RVB Hurricane 3 Chime, RVB Hurricane 5 Chime and Twin RVB Hurricane 5 Chime available to suit your specific model.

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.

And includes all these great features to make your Auscision 48 Class model drive and sound impressive
