About the NSWGR 41 Class Locomotive

The 41 class were a class of diesel locomotives built by British Thomson-Houston in the United Kingdom for the New South Wales Government Railways during 1953-54. In 1950 the New South Wales Government Railways ordered 10 diesel locomotives from Australian General Electric. The construction was then sublet to British Thomson-Houston with the body built by Metro Cammell, in the United Kingdom. The first loco No.4101 entered service on the 1st December 1953 with the last No. 4110 on the 10th February 1955. All were delivered painted in Verdant Green, then during the 1960s all were repainted Indian Red.

From their earliest days the locomotives were troublesome and suffered failures including overheating and fires. To overcome this problem the radiators were relocated further to the ends of all ten of the locomotives and air ducting was modified. In addition, two had their mufflers relocated and this modification was considered a success, but not rolled out across the rest of the 41 class. The locomotives were equipped to operate in multiples however the cooling system layout saw radiator heat passing from the leading locomotive to the trailing one, which resulted in the equipment being removed.

By the early 1960s the twin Paxman 12-RPHL engines showed signs they were coming to the end of their useful life, a repowering option was considered. With the cost of repowering and overhauling the 41 Class being two-thirds that of a new 48 Class and repair costs over nine times greater, it was decided not to proceed with this option.

After only four short years of service 4106 was withdrawn following two electrical fires. On April 1st, 1961, locomotive 4105 was withdrawn followed by 4108 on the 10th September 1969. When overhauls ceased for the rest of the class in 1972 each locomotive was then withdrawn from 1973 as they suffered a major failure. The final locomotive 4102 was withdrawn on the 19th July 1975 and is the only one in its class that was preserved.

The 41 class were mainly confined to metropolitan Sydney operating local trip workings and shunting at the Enfield yards.

DCC with Sound and Light Modifications

In March 2016, Austrains released the 41 Class Locomotives which includes an 8 Pin socket for fitting a DCC decoder plus 2 solder pads for wiring the factory installed speaker to the decoder. In DCC all lights will operate directional.

For this installation we recommend the ESU LokSound V4.0 (Sound) with our Custom Sound Project for the 41 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.

We offer a light modification for this 41 Class to separate the 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 the front and rear red markers switched on at the same time as per NSWGR practice. The front and rear headlights can operate on/off non directional. You can also still operate all the light directional as the way the model was delivered.

DCC Solutions Lighting Modifications

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

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

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

3) Rear Headlight - on/off directionally with the headlight 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

8) Directional Marker Lights  - 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 41 Class Custom Sound Project is packed with sounds and features not found on other Sound Decoders

Our NSWGR 41 Class Custom Sound Project now includes these great features:

Dual Paxman V12 Prime Mover Sound

As the 41 Class Paxman engines were renowned for being rough at idling we have incorporated this in our Custom Sound Project.

Let you 41 class sit there idling and listen to how it idles...rough!!

Running low, then high, then missing a bit then maybe high again or possibly low, the idle simply does not run smooth like other diesel engines.  

Coasting on Demand
This feature allows you to enter coasting mode whenever you what 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 terrain, the engineer can coast to maintain a certain speed. By pressing the coast function button, the sound drops from wherever you are to idle and remains there. Using the throttle speed control, you can now speed up or slow down the train with the sound remaining constant, at idle.
Press the function button to exit coasting and the sound will exit idle and return to whatever speed is set when exiting.
Independent Brake
Simply press the Independent Brake Function button and your locomotive will come to a stop at a much short distance than if you were to bring the loco to a stop by reducing the speed throttle.Press the function button to release the brake and your loco will move off again or remain stationary.

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 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 Austrains 41 Class drive and sound impressive
  • Dual Paxman V12 Prime Mover with rough idle
  • Random Start-up sequences.
  • Air and Brake Release Sounds when loco moves off and stops including Brake Squeal.
