About the C44aci Class Locomotive

The C44aci is a heavy-duty diesel-electric locomotive designed by UGL Rail and built at the Broadmeadow factory in 2008 with 175 unit built. The design is based on the National Rail NR class but with some modifications and upgraded features and was built in response to a tender issued by Pacific National, who required a locomotive to match the performance of their existing 90 class units when hauling heavy coal traffic, while having the ability to work high speed intermodal services, with the change between applications to be simple. 

The existing NR class locomotive design was used as a base, but with alterations including:

  • Higher horsepower prime mover yet retaining the older GE 7FDL-16 as used in the NR

  • Smaller main alternator

  • Enlarged radiator size now overhangs the walkway at the number 2 end to cope with the more powerful engine

  • AC traction motor, allowing an increase in haulage capacity

  • Addition of inline refuelling fittings

  • Isolated cab for reduced noise and vibration

  • A new design of fabricated bogies

  • Increased use of modular construction

  • Revised transition curves in the under frame to reduce the probability of fatigue cracking

  • Various body and cab modifications

A unique feature of the locomotive is the ability to reduce its weight by the level of fuel carried, depending on its operation: 

  • In heavy haul coal operations, the locomotive can maximise a fuel loading of up to 13,500 litres, increasing the mass to 139 tonnes, which consequently creates greater track adhesion.

  • For high-speed intermodal applications, the fuel tank capacity is lowered to 7,300 litres, which equates to 134 tonnes of mass to allow additional locomotive power that can be utilised to reduce the travel time of the train.

  • An intermediate fuel level of 10,750 litres also available.

The C44aci locomotive is operated by a number of rail freight operators, including:

Pacific National - 39, Aurizon - 51, Chicago Freight Car Leasing Australia (CFCLA)/RailFirst Asset Management - 10, Centennial Coal (Southern Shorthaul Railroad) - 7, One Rail Australia - 45, Mineral Resources - 6, Fletcher International Exports - 3

Crawfords Freightlines - 2, Qube Holdings - 12

DCC with Sound and Light Modifications

In December 2016, Auscision released the C43/44aci Class locomotive, which includes a 21 Pin socket for fitting a DCC decoder plus a speaker enclosure that suits the DCC Solutions 16x35mm Speaker. The model includes operating headlights, marker and ditch lights There are 2 micro switches under the model for turning lights on/off in DC. In standard DC/DCC, all lights will operate directional.

For the Auscision C43/44aci Class installation, we recommend the ESU LokSound 5 (Sound) with our remastered Custom Sound Project for the C43/44aci Class or the LokPilot 5 (No Sound) for those not wishing sound

We offer a light modification for this C43/44aci Class to separate the lights for a more prototypical operation.

Standard factory lighting in the model has all lights “ON” in the direction of travel, requiring just 2 function lighting outputs in DCC.

Upgraded from the factory standard 2 to either 6, 8 or 10 Function lighting outputs with the DCC Solutions light modification where we will separate all the headlights, white markers lights, red markers lights and ditch lights for individual DCC control. Plus, the ditch lights can be individually separated for allowing alternate flashing ditch lights when the horn is blown to provide you with total prototypical lighting operation when running your Auscision C43/44aci Class 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, so 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 C44aci Class Custom Sound Project

is packed with sounds and features not found on other sound decoders, especially factory fitted sound.

Factory Fitted Sound only offers you very basic sound

So why not get fully featured sound from DCC Solutions

Our Custom Sound Project now includes these fantastic features:

Custom Built C44aci Class Sound Project

This is not just a basic factory sound project but a completely custom-built sound project by DCC Solutions that contains recorded sounds with customised sound programming plus extra features that will make your C43/44aci Class Auscision model a uniquely, impressive driving sounding with prototypical lighting operation loco that will turn heads!

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 Australian Nathan K-5UL- 5 Chime playable and short blast horn with optional alternate flashing ditch lights.

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.
