DCC Sound Installation


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 with a total of 56 units built.
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, handrails running the full length of the loco, and also an air conditioning which forms the now characteristic nose of the class. A ‘D’ suffix was used to identify the Driver Only locos.
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 2015, Wuiske Models Haskell Co released the QR 1720 Class locomotive, which included an 8 Pin socket for fitting a DCC decoder and no provision for a speaker. The model included LED headlights and number boards only.
The models are available in both HOn3½ (12 mm) and HO (16.5 mm) gauges.
For this DCC installation, we recommend the ESU LokSound 5 (Sound) with our remastered Custom Sound Project for the Queensland 1720 Class 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, with this requiring just 2 function lighting outputs in DCC. We offer a light modification to separate the headlights and numberboards for individual DCC control.
The DCC Solutions Queensland 1720 Class Custom Sound Project is packed with sounds and features not found on other sound decoders, especially factory fitted sound
So why not get fully featured sound from DCC Solutions
Our Custom Sound Project now includes these fantastic features:
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.
Dynamic Brake Logic
There are no Dynamic Brakes on a 1720 Class Locomotive, however we have included Dynamic Brake Logic in this sound project to allow your 1720 Class loco to run in a trailing consist with other locos that may have Dynamic Brakes.
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 WABCo 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.
