Wuiske Models QR 1550/2400 Class Diesel Locomotive

DCC Sound Installation with Light Modifications

Now available with our NEW Remastered Custom Sound Project

including "Full Throttle - Drive Hold" feature

About the QLD 1550 Class

The 1550 class are a diesel locomotives built by Clyde Engineering, Eagle Farm for Queensland Railways between 1972 and 1976. The 1550 class were the first locomotives in Queensland to be fitted with low noses. An initial order for 16 locomotives was followed by 11 that were financed by the Queensland Phosphate mining group. The second batch differed in having a lower roofline to give better clearance when operating under wires.

Two have been scrapped, while between 1997 and 2004, 19 were rebuilt as 2300 class locomotives and six as 2250 class locomotives at Redbank Railway Workshops.

About the QLD 2400 Class

The 2400 class are a diesel locomotives built by Clyde Engineering, Eagle Farm for Queensland Railways in 1977-1978

The 2400 class were an evolution of the 1550 class. They differed in having the modular control system incorporated into the electrical cabinet. Originally it was intended to continue their number sequence from the last 1550, i.e. the first would have been 1577, but this would have required the 1600 class to have been renumbered, so they were instead numbered as the 2400 class.

Between 1999 and 2002, eighteen were rebuilt as 2300 class locomotives at Redbank Railway Workshops. The remaining six were withdrawn, with one exported in August 2013 to South Africa

The 2400 class worked typically on general freight traffic around Queensland, along with some passenger services.

DCC with Sound and Light Modifications

In January 2015, Wuiske Models Haskell Co released their QR 1550 Class Locomotives, which includes an 8 Pin socket for fitting a DCC decoder but no provision to install a speaker. In DC/DCC, all lights operate directional.

The models are available in both HOn3½ (12mm) and HO (16.5mm) gauges, with three versions to suit modellers from 1973-2006 eras.

For this DCC installation, we recommend the ESU LokSound 5 (Sound) with our remastered Custom Sound Project for the QLD 1550/2400 Class or the LokPilot 5 (No Sound) for those not wishing sound.

We offer a light modification for the Wuiske 1550/2400 Class to separate some lights 

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 4 Function lighting outputs with the DCC Solutions light modification, where we will separate the headlights with white markers and numberboard lights for individual DCC control to provide more lighting options when running your Wuiske 1550/2400 Class model. Directional light control will still be available.

The DCC Solutions QLD 1550/2400 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 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 Queensland 1550/2400 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 1550/2400 Class Wuiske model a uniquely, impressive driving and sounding 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

New remastered WABCo Pneuphonic A&B series 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.
