About the CL-CLF-CLP Class Locomotive
The CL class were a class of 17 diesel locomotives built by Clyde Engineering, Granville for the New South Wales Government Railways between 1970 and 1972, to work freight and passenger services on the Trans Australian line. They were some of the first 3000 horsepower locos to see service in Australia.
In 1992, Morrison Knudsen Australia purchased the class from Australian National Railways (ANR) for remanufacturing.
This process brought the class up to modern standards, with numerous changes throughout the mechanical and electrical systems. At this point, they were converted into two subgroups, 7 CLF (for Freight) and 10 CLP (for Passenger). The main difference was the fitting of Head End Power to the CLP type for passenger duties to operate the Indian Pacific, Ghan, and Overland passenger services.
Following the rebuild, they were leased back to ANR under a 12-year arrangement. They took up their intended duties as they re-entered service in 1993 and 1994.
As a result of problems from the transfer of functions to the National Rail Corporation, and growing debt levels, the Commonwealth Government decided to sell ANR in 1996. So this class ending up with the successful bidder for the freight operations, GWI Australia, in late 1997. Their Australia Southern Railway became part of the larger Australian Railroad Group (ARG) in 2000, following GWI’s purchase of Westrail. Queensland Rail (QR) purchased the WA and NSW operations of ARG in 2006, with the acquisition also including ARG’s Melbourne to Adelaide P&O intermodal service.
At this time, five CLF class were working this traffic, and were allocated to QR. Five CLP class were part of ARG’s NSW Manildra fleet, also joining QR. The other seven remained with the scaled-down GWA for mostly SA operations. QRN’s fleet has been concentrated on intermodal services since then, with their use expanding to nationwide as QR National’s services (QRN).
Currently, only 10 remain in service under private ownership.
DCC with Sound and Light Modification
The Auscision CLF/CLP Class was released in January 2025 which includes the 21 Pin MTC socket for fitting a DCC decoder and came with their Vandersound speaker enclosure that requires 2 speakers installed (11 mm X 15 mm).
There are micro switches under the model for turning lights on/off in DC. In standard DCC, all lights will operate directional.
For this DCC installation, we recommend the ESU LokSound 5 (Sound) with our remastered Custom Sound Project for the Australian National CLF/CLP Class or the LokPilot 5 (No Sound) for those not wishing sound.
Our Custom Sound Project is NOT the Generic sound file from ESU and Auscision.....It's Better!
Standard factory lighting in the model has all lights “ON” in the direction of travel. The DCC Solutions CLF/CLP Custom Sound Project has the headlights, ditch lights, numberboards, white markers and red marker lights set up for individual DCC control. Along with flashing ditch lights when sounding the horn, this will provide more prototypical lighting operation when running your Auscision CLF/CLP model. Directional light control will still be available.
Unlike ESU/Auscision factory sound which uses 2 sound slots to operate the lights, our light modification does not use any sound slots for lighting. Therefore, all the 10 sound processing channels are available to play sounds when using all the lighting, so you will get the full sound experience all the time.
The DCC Solutions CLF/CLP Custom Sound Project
is packed with sounds and features not found on other sound decoders,
especially factory fitted sound
Factory Fitted Sound only offers very basic sound and features
So why not get fully featured sound from DCC Solutions
Our Custom Sound Project now includes these fantastic features:
Custom Built CLF/CLP Class Sound Project
This is not just a basic factory sound project but a completely custom-built sound project by DCC Solutions. It contains recorded sounds with customised sound programming plus extra features that will make your CLF/CLP Class Auscision model a uniquely, impressive driving sounding with prototypical lighting operation loco that will turn heads!
Three Sound Projects Available:
EMD 16-645E3C Prime Mover Sound for the CLF Class
EMD 16-645E3C with Head End Power (HEP) Prime Mover Sound for the CLP Class
Full Throttle – Drive Hold
This feature allows you to simulate a hard-working loaded 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, so this can simulate a hard-working locomotive. This exciting feature gives the operator the ability to have the loco crawling in notch 8 or coasting at 100 km/h along the track. Release the Drive Hold function button, and you simply go back to throttle-controlled speed, motion, and sound. 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 sound or sound from other providers will not stop your loco at speed step 0 with the drive hold switched on, which can damage your model because you ran into something.
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, the sound will return to the speed that's 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. The brake can also be used while driving to slow the locomotive up.
Working Dynamic Brake
Apply the Dynamic Brakes and the Prime Mover will wind down to idle and slow up, then 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 return to it's notched speed and the fans will turn off.
Brake Squeal on Deceleration
Activate this function and when you reduce the throttle speed, your locomotive will begin braking and slow up quicker as you continue to lower the throttle speed, and you will hear the squeal of the brakes. Accelerating will release the brakes.
Random Start-up Sequences with Move Off and Stopping Sounds
Now, with random start-up sequences, 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.
Remastered Horn Sounds
A new remastered Leslie SuperTyfon RS-5T or Nathan P5 Chime playable and short blast horn.
Random Sounds
While the factory fitted sound will only offer you 1-2 random sounds, DCC Solutions will have up to 10 random sounds that will play when either the loco is stopping or moving, to create even more realism to running your model.
Manual Notching
For those who really want to drive their train and manually control the notching rather than letting the decoder do it.
