About the NSWGR 40 Class Locomotive

The 40 class were a class of diesel locomotives built by Montreal Locomotive Works, Canada for the New South Wales Government Railways in 1951/52 with a total of 20 units and were the first mainline diesel-electric locomotives to be built for the NSWGR. They were based on the ALCO RSC-3 design with some slight modifications. These included a cab sides that angled to reduce the width of the locomotive at the top of the cab roof, and placement of the handrails on the car body rather than the standard walkway handrail arrangement.

The 40 class were shipped from Canada in grey undercoat and were painted verdant green, similar to the NSWGR 38 Class Steam locomotive, at Eveleigh Carriage Works also where the 38 Class were painted. For the 1954 Royal Tour of Queen Elizabeth II, 4001 and 4002 were repainted in a special royal blue livery. By the early 1960s, all were repainted Indian red.

The first 40 Class, 4001 enter service in November 1951 with the last entering in May 1952. They were originally used on heavy freight services from Sydney to Broadmeadow and later on North Coast services to Brisbane and Main South line services to Albury. When the 40 Class started to show their age during the late 1960s, consideration was given to rebuilding the class. This included major electrical work was required but due to their lack of power compared to other diesels, the 40 class were withdrawn from May 1968 with the last being taken out of service in December 1971.

The New South Wales Rail Transport Museum preserved 4001, and it was returned to traffic in October 2010 painted in the blue livery. Also preserved were 4002 and 4006 with the remaining 17 scrapped.

DCC with Sound and Lighting Modifications

In October 2017, Eureka released their first batch of DC Ready, non-sound 40 Class Locomotives which includes an 8 Pin socket for fitting a DCC decoder but no speakers installed. In DC and DCC, all lights will operate directional.

Soon after the initial DC release, Eureka released a QSI Sound DCC Version, which seemed to be lacking in many areas.


For this DCC installation, we recommend the ESU LokSound 5 (Sound) with our remastered Custom Sound Project for the NSW 40 Class partnered with the DCC Solutions Custom Hurricane C40 Speaker or the LokPilot 5 (No Sound) for those not wishing sound.

Upgrade the factory QSI Sound Decoder with the ESU Sound Decoder programmed with 40 Class Custom Sound project and really improve the sound in your model.


We offer a light modification for this 40 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 to operate the lights.

Upgraded from the factory standard 2 to 6 Function lighting outputs with the DCC Solutions light modification.  It includes separating the headlights, white markers and red markers lights for individual DCC control to provide more prototypical NSWGR practice lighting operation when running your Eureka 40 Class model. Directional light control will still be available.

The DCC Solutions NSW 40 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.

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 NSW 40 Class 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.
