About the 45 Class

The 45 class are a class of diesel-electric locomotives that were built for the New South Wales Government Railways between 1962 and 1964. A total of 40 locomotives were built by Alco's Australian licensee AE Goodwin, Auburn, and are based on the Alco DL-541 model. In June 1962 the first of theses locomotives,4501, entered service initially on the Main Southern line.

During the remainder of the 1960s and the early 1970s the 45 class were seen on passenger and freight workings on most main lines across the NSW network.  During 1971 the class was then allocated to Broadmeadow, where they remained until their withdrawal. In June 1984 they were banned as a lead locomotive as a result of union demands and were relegated to trailing unit status. Due to this they were mostly confined to workings in the northern region of NSW apart from some isolated occasions working freight only and were able to be used on Sydney metropolitan trip and Liverpool Range banking duties.

They remained in service until replaced by FreightCorp's 82 Class in 1994/95. Thirty-two were auctioned in December 1994 with most being sold for scrap. Five have been preserved 4501 (Operational),4502, 4520 (Operational), 4521, 4528 with 4532(45s1) and 4537(103) still operational by private operators. 

DCC with Sound and Light Modifications

In January 2015, Auscision released the 45 Class locomotive which includes a 21 Pin socket for easily fitting a DCC decoder plus a speaker enclosure that suits a 16x35mm speaker. There are micro switches under the model for turning lights on/off in DC. In DCC all lights will operate directional with no individual control.

We offer a light modification for Auscision's 45 Class to separate the lights for a more prototypical operation.

We can separate the front headlight, 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 45 Class Locomotive.

You can also still operate all the lights directional as the way the model was delivered.

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

1) Headlights - directional with 1 function
2) Marker Lights - directional with 1 function
3) Front Headlight - on/off with 1 function

4) Front White Markers - on/off with 1 function

5) Front Red Markers - on/off with 1 function

6) Rear White Markers - on/off with 1 function

7) Rear Red Markers - on/off with 1 function

For this installation we recommend the ESU LokSound V4.0 (Sound) or the LokPilot V4.0 (No Sound) for those not wishing sound. Alternatively you may wish to choose the ESU Select Sound Decoder or the TCS (Train Control Systems) 21 Pin non sound decoder. We offer several different options of DCC installation for this model to suit all budgets.

The DCC Solutions NSW 45 Class Custom Sound Project - ALCo 12-251C

Our Custom Sound Project now includes these new 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.

Coasting on Demand

Pressing F5 will activate coasting on demand to suit your running environment allowing variable speed coasting so changes in speed will not turn it off until you turn it off.

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.

Move Off and Stopping Sounds
When your locomotive begins to move you will hear the sounds of brakes releasing plus some random sounds programmed into our Custom Sound Project that are activated with the moving off and stopping of the locomotive to add to the realism.
Remastered Horn Sounds
A new remastered NSWGR WABCo A/B Series playable and short blast horn

And includes all these great features to make your Auscision 45 Class drive and sound impressive.

  • Full Throttle Drive Hold - Lock the loco speed and control the sound independently to simulate a heavy loaded or empty train
  • Dynamic Braking - Effectively halves the deceleration momentum value to allow increased braking as you reduce the throttle speed.
  • Coasting On Demand
