About The DEB Set Rail Cars

The 900/800 class railcars also known as the DEB sets were diesel multiple units built by the New South Wales Government Railways between November 1951 and November 1960. As introduced, the DEB sets were formed as a four-car with a power car at either end of two trailer cars. The set consisted of a HPF power car with luggage compartment and second class seating, a TB first class sitting car, a TFR second class sitting car with buffet and a PF power car with second class seating. The DEB sets were very similar to the 600/700 class railcars, however they were intended for long distance services and air-conditioned.

The first four-car set entered service in November 1951, powered by four 240 horsepower horizontal in-line six cylinders, four stroke Hercules DFXH-F diesel engines. These engines and their transmissions proved unreliable, and the set was withdrawn after less than six months in service in May 1952. The construction of the DEB sets was suspended until a satisfactory engine solution was arranged. The upgrade involved the fitting of two General Motors Detroit Diesel 6/110 inclined in-line six cylinder, two-stroke diesel engines and a new hydraulic transmission to each power car. With these changes, production of the DEB set resumed, and two 4-car sets entered service in May 1955.

 

The DEB sets were able to provide flexible main line services with a seven or eight car train operating from Sydney to a major junction station and then dividing into two trains to travel through to their destinations. They pretty much serviced every regional rail line. The North Coast Daylight Express, Canberra Monaro Express, Far West Express from Dubbo to Bourke, Cobar and Coonamble, Northern Tablelands Express, Riverina Express, and later in their service some CityRail services on the Main South and South Coast lines. 

 

During the 1980s, the DEB sets saw some changes. A program of retrofitting higher performance Cummins NTA-855-R4 engines with a different transmission commenced and along with the introduction of the XPT into service in 1982, a number of the DEB set services had been taken over by the XPT. From April 1989 all the DEB sets were reallocated to CityRail to operate South Coast services to Bomaderry and Main Southern line services to Moss Vale and Goulburn. The DEB sets began withdrawn from August 1994 with the last being taken out of service in February 1995.

DCC with Sound and 3 Car Modification

In February 2025, Auscision released the DEB Set Railcars, which includes the 21 Pin MTC socket for fitting a DCC decoder in the front HPF car and a speaker enclosure that is designed for a 40 × 20 mm speaker.

An interesting addition of a second speaker enclosure is included in the rear PF car, but there is no option to install a sound decoder in that car. If a speaker is installed, sounds coming from the rear car will be exactly the same as the front car, meaning no sound distinction between the front and rear cars. Auscision has warned the use of two speakers will destroy the sound decoder and void all warranties.

DCC Solutions has a “Solution” to this problem that allows the use of two speakers if it is desired.

DCC Solutions offers a modification to run your DEB Railcars as a 3, 4, 7 or 8 car set.

WARNING: Auscison has advised that the DEB Set must only be run as a 4 car set.

Due to a wiring issue with the model, you are unable to run your DEB railcars as a prototypical 3 or 7 car set.

As part of the sound installation, additional modifications can be made to the wiring in the model to rectify this issue so that you can run the model with any number of cars you desire.

 

For this DCC installation, we recommend the ESU LokSound 5 (Sound) with our remastered Custom Sound Project for the NSW DEB set or the LokPilot 5 (No Sound) for those not wishing sound.

Standard factory lighting in the model has all lights “ON” in the direction of travel. The DCC Solutions DEB Set Custom Sound Project has the headlights, white markers and red marker lights set up for individual DCC control to provide more prototypical lighting operation when running your Auscision DEB set railcar. 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 NSW DEB SET Railcar 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 the very basic sound 

So why not get fully featured sound from DCC Solutions

Our Custom Sound Project now includes these fantastic features:

Custom Built NSW DEB SET Railcar Sound Project

This is not just a basic ESU factory sound file found on the sound equipped models.  It is a completely custom-built sound project by DCC Solutions that contains recorded sounds with customised sound programming plus extra features that will make your NSW DEB Set model a uniquely, impressive driving and sounding railcar that will turn heads!

Our unique project offers the selection of two types of engines that were used on the DEB set, allowing you to have the correct prime mover sound for your pre or post 1980s modelling era. 

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.

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

New remastered NSW DEB Set 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.
