About the NSW 43 Class Locomotive

The 43 class were a class of Australian diesel locomotives built by A Goninan & Co, Broadmeadow for the New South Wales Government Railways in 1956-57. The class of only six locomotives were unique in Australia in having Alco power units in GE Transportation Systems designed bodies.

The 43 class were initially used on the Main Western line from Sydney to Orange, prior to electrification of the line to Lithgow in June 1957, appearing regularly on the Central West Express. Subsequently, they were transferred to Broadmeadow Locomotive Depot operating from Gosford to the Queensland border via both the North Coast and Main North lines. They also saw service on the Main South line.

In August 1974, 4301 was taken into Chullora Workshops for a regular overhaul, however a decision was made to use it as spares for the remaining units. In the following years, four more were later scrapped with the last, 4306, being withdrawn in October 1979 and placed by the Public Transport Commission (PTC) in the custody of the New South Wales Rail Transport Museum. It is now a designated NSW heritage item. It was transferred to Thirlmere in March 1980 and in 1986, the Illawarra branch of the Rail Transport Museum commenced overhauling 4306. The locomotive returned to traffic in June 1996 and has since been used extensively on charters in New South Wales as well as interstate to Brisbane and Melbourne.

DCC with Sound and Light Modifications

In November 2015, Auscision released the 43 Class locomotive which includes a 21 Pin socket for fitting a DCC decoder plus a speaker enclosure that suits a 20x40mm speaker.  In DCC all lights will operate directional with no individual control.

For this installation we recommend the ESU LokSound 5 (Sound) with our Custom Sound Project for the 43 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.

DCC Solutions offers a light modification for the 43 Class to separate the lights for a more prototypical operation.

We can separate the front headlight, white marker lights and red marker lights for a more prototypical operational practices in DCC. Both the white and red marker lights at the front and rear can be controlled individually or directionally as well as the front and rear headlights. That allows for no rear red marker lights to be on when the loco is carrying a load behind it or both the front and rear red markers switched on at the same time when the locomotive is standing in a siding or shunting and you can even run with just the front white markers switched on. You can control what lights you want switched on depending on how you are running your 43 Class Locomotive. 

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 button

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! 

The DCC Solutions NSW 43 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 43 Class Sound Project includes these fantastic features:

Correct Sound for the 43 Class Locomotive

Our DCC Solutions Custom Sound Project with the ALCo 12-244 Prime Mover Sound.

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 with the drive hold on.

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.

Working Dynamic Brake

Apply the Dynamic Brakes and the Prime Mover will wind down to idle while 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 returned to it's notched speed and the fans will turn off.

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.

Remastered Horn Sounds
A new remastered NSWGR Nathan P5 playable and short blast horn with Rear Single Trumpet Horn or a Front 2 Trumpet Horn to suit your model.
Random Sounds 
Up to 10 random sounds that will play when either the loco is stopping or moving create even more realism to running your model.

And includes all these great features to make your Auscision 43 Class drive and sound impressive.
