About the NSW 73 Class Locomotive
The 73 class are a diesel-hydraulic locomotive built by Walkers Limited, Maryborough, Queensland for the New South Wales Government Railways between 1970 and 1973.In October 1969 the New South Wales Government Railways placed an order for 20 Bo-Bo shunting locomotives. These were the only New South Wales locomotives to be built in Queensland. The first unit was delivered in October 1970. When the all of the 20 locomotives were delivered, all steam shunting on North Coast line, at Goulburn and the Sydney Metropolitan area had been replaced. In July 1971 a further 30 units were ordered and when the last of these arrived in March 1973 it brought to an end all remaining steam shunting operations in New South Wales.
The New South Wales Government Railways purchased the class mainly for shunting and their prohibition from mainline use was 'officially' due to the lack of vigilance controls. However, despite its absence, the class was still seen on many suburban trip workings and when mainline operation was a necessity, there seemed to be no hesitation to use them. Multiple unit operation was common and a number of units were fitted with exhaust gas scrubbers for use on Eastern Suburbs Railway construction in the 1970s.
With a reduction in locomotive hauled passenger trains and the closure of a number of yards, withdrawals began in February 1987. By October 1991 only three remained in service with FreightCorp. One was repainted into CountryLink livery for use as a depot shunter at the XPT Service Centre.
Disposals commenced in 1990 with three sold to the Canberra Railway Museum. Four were sold to Manildra Group in 1991, while many were sold to Queensland sugar cane companies. A number have also been preserved 7307, 7320, 7321,7324, 7329, 7335, 7344, 7350.
7301 & 7344 were placed on RailCorp's Heritage & Conservation Register. However, 7301 was subsequently scrapped in January 2014.
In all 15 remain in service, 8 preserved, 16 stored and 11 were scrapped.
DCC with Sound and Light Modifications
The Auscision 73 Class was released in February 2013 as a DC model only. There was no provision for DCC and the model requires a complete rewire to operate in DCC. Three switches located internally on the board enabled you to turn the headlights, marker lights and number board lights on/off in DC. To operate these lights in DCC the light boards require extensive modifications as they are not suitable for DCC operation and won't work.
In January 2019, Auscision released a second run as a DC model only. However, this time it is a DCC ready model as they have included the European 6 pin DCC socket. Unusual choice as we were able to fit an adapter board with a 21 pin decoder in the rear of the original release so it was quite possible for this option to be included in the second release. So, this new model is DCC ready not DCC Sound Ready.
To achieve the best sound for this installation we recommend the "NEW" ESU LokSound V5 (Sound) with our Custom Sound Project for the 73 Class. The LokPilot V4.0 (No Sound) is for those not wishing sound.
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 full individual light control for Auscision's 73 Class to allow more prototypical light operations.
A light modification is available to separate the front headlight, numberboards, white markers 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 73 Class Locomotive.
You can also still operate all the lights directional as the way the model was delivered.

Correct Sound for the 73 Class Locomotive
Our DCC Solutions Custom Sound Project with the Caterpillar D379 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.
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.
