Wuiske Models QR 1720

DCC Sound Installation

Now available with our NEW Remastered

LokSound 5 Custom Sound Project 


About the 1720 Class

The 1720 class are a class of diesel locomotives built by Clyde Engineering, Eagle Farm for Queensland Railways between 1966 and 1970.

The 1720 class were an evolution of the 1700 class. They operated throughout all of Queensland on branch line freight, suburban and mainline passenger services as well as shunting duties. Later they were modified for driver only operation receiving a larger windscreen.

Some have been exported, although the majority as at January 2014 remain in service. Unit 1741 was acquired for preservation by the Queensland Diesel Restoration Group in October 2016.

DCC with Sound and Light Modifications

In April 2017, Wuiske Models Haskell Co released their QR 1720 Class Locomotives which included an 8 Pin socket for easily fitting a DCC decoder.

The models are available in both HOn3½ (12mm) and HO (16.5mm) gauges

For this installation we recommend the ESU LokSound 5 (Sound) with our Custom Sound Project for the 1720 Class or the LokPilot V4.0 (No Sound) for those not wishing sound. We offer several options of DCC installations for this model to suit all budgets and can supply the decoders only for the DIY installers.

We have tweaked the motor control of the ESU decoder to provide super slow smooth speed which is perfect for shunting operations allowing the loco to move ever so slowly towards its rolling stock. Also, for those wanting the locomotive to move off slowly and build up speed like the prototype. You will be impressed with the smooth slow speed motor control.

The DCC Solutions QR 1720 Class Custom Sound Project - EMD 8-645E

is packed with sounds and features not found on other Sound Decoders

Our Custom Sound Project now includes these fantastic 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. 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 fitted or downloadable sound will not stop your loco at speed step 0 with the drive hold on.

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 the

NSW's 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 and the sound will exit and return to whatever speed is 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.

Dynamic Brake Logic Only

The 1720 did not come with Dynamic Brakes, however we have included Dynamic Brake Logic that allows you to run your 1720 class loco in consist with other locos that have Dynamic Brakes to enable the 1720 to drop to idle and respond to braking in the same way as the Dynamic braking loco.

Random Start-up Sequences with Move Off and Stopping Sounds

Now with random start-up sequences including hot or cold engine starts 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.

Coupling and Release with Shunting Mode

Activate coupling or release and your loco will automatically reduce its speed to allow for a more realistic coupling or release operation. Once the operation is completed your loco will continue to run at slow speed for a few more seconds before returning to the speed set on your throttle.

Remastered Horn Sounds

WABCo A/B Series playable and short blast horn.

Random Sounds

At least 12 random sounds that will play when either the loco is stopped or moving to add to the realism. 

And includes all these great features to make your Wuiske 1720 Class drive and sound impressive.

  • EMD 8-645E Roots Blower Prime Mover.
  • Short Blast and Playable Horn
  • Random Start-up sequences including Automatic Hot or Cold Engine Start.
  • Air and Brake Release Sounds when loco moves off and stops including Brake Squeal.
  • When the loco stops after braking the compressor cuts in to fill the reservoir and will turn off when the tanks are full.
  • Speed sensitive Wheel Squeal and Rail Noise when the loco moves off.
  • Full Throttle Drive Hold - Lock the loco speed and control the sound independently to simulate a heavy loaded or empty train
  • Dynamic Brakes Logic: Allows you run your 1720 in consist with other locos with dynamic brakes.
  • Coasting On Demand
  • Working Brake to bring your locomotive to a stop even when Full Throttle Drive Hold is active unlike other ESU sound files.
  • Directional Coupling and Release with brake line release with auto active shunting mode to reduce the speed of the loco for shunting
  • Stop & Drive Random Sounds including fans, compressor, rail noise, track wheel squeal, air releases and more!
  • Manual Ratchet Handbrake
  • Low beam to High beam Headlight operation
  • Modified Lighting Option to separate the headlight from the number boards.
  • And more (See below for full list)
  • Motor settings and sound volumes tuned to specifically suit the Wuiske 1720 Locomotive Model.
  • Individual sounds slots and master sound volumes can be adjusted by the user to suit personal requirements.
  • Full function button remapping to suit your personal requirements.
  • This Sound Project is also suitable for other brands of 1720 Class Models.
