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 1960's 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 1960's, consideration was given to rebuilding the class including major electrical work was required but due to their lack of power compared to other diesels, the 40 class were withdrawn from May 1968 with the last being taken out of service in December 1971.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, non-sound 40 Class Locomotives which includes an 8 Pin socket for fitting a DCC decoder but no provision for a speaker. In DC and DCC all lights will operate directional. Soon after the DC release they released a QSI Sound DCC Version which seemed to be lacking in many areas. 

For this installation we recommend the ESU LokSound 5 (Sound) with our Custom Sound Project for the 40 Class or the LokPilot V4.0 (No Sound) for those not wishing sound.  We 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.

We offer a light modification for this 40 Class to separate the lights for a more prototypical operation.

Factory Lighting

1) Front Headlight, White Markers and Rear Red Markers on/off when travelling forward with the headlight button.

2) Rear Headlight, White Markers and Front Red Markers on/off when travelling in reverse with the headlight button.

DCC Solutions Lighting

For an upgrade to 6 Function Standard Light Modification we can separate the lights as follows:

1) Front Headlight - on/off directionally with the headlight button

2) Rear Headlight - on/off directionally with the headlight button

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

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

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

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

7) Directional Marker Lights - on/off with 1 function

8) Front Headlight - on/off with 1 function button

With our light modifications you can operate the lights on your model locomotive closer to the real thing! 


We have created a custom sound project for the 40 Class with the sounds of 4001 and the ALCO 12-244 engine so now with our lighting modifications you can finally own a great sounding 40 Class with a more prototypical lighting.

The DCC Solutions NSW 40 Class Custom Sound Project 
is packed with sounds and features n
ot found on other sound decoders especially factory fitted sound.

Factory Fitted Sound only offers you the very basic sound for your model 

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 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. 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 fitted sound will not stop your loco at speed step 0 or by trying to use the brake with the drive hold on. So watch out you don't crash your loco.

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.

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.

Coupling and Release with Shunting Mode
Activate coupling or release and your loco will automatically reduce its speed to allow 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.

Manual Notching

For those who really want to drive their train and manually control the notching rather than letting the decoder do it.

Remastered Horn Sounds
A remastered NSWGR 40 class playable and short blast horn.
Random Sounds
While the factory fitted sound will only offer you 1-2 random sound, DCC Solutions will have up to 12 random sounds that will play when either the loco is stopping or moving as we have been doing for years in all our Custom Sound Projects.
