About the NSW 70 Class Locomotive
The NSW 70 class were a class of diesel-hydraulic locomotives built by Commonwealth Engineering, Granville for the New South Wales Government Railways in 1960-61. They were ordered to replace steam locomotives at Port Kembla. Only 10 units were built with the first locomotive, 7001, entering service on the 15th of August 1960 and the last to enter service, 7010, on the 11th of May 1961.
The 70 Class were a very different type of locomotive. They were diesel-hydraulic rather than diesel-electric. But the most obvious difference was they were of an 0-6-0 design rather than a more conventional Bo-Bo or Co-Co wheel arrangement. Their light axle load was specified to allow them to work on the industrial branch and wharf lines in Port Kembla (Near Wollongong, NSW) where they would spend most of their working life around that area. They were also seen shunting around other yards in Sydney including Darling Harbour and Chullora while occasionally used as passenger trains. The 70 class had been found to travel as far as Casino in northern NSW.
On 10 February 1984, 7009 was taken out of service and sent to Eveleigh Railway Workshops with 7008 following on 21 June and 7002 on 13 August, all three were officially withdrawn. On 12 November 1984, the 73 class took over all shunting and transfer duties at Port Kembla resulting in only 3 of the 70 class locos to remain operational. On 10 September 1986, loco 7010 last operated and 7006 stopped the following day bringing an end to the NSW 70 class in operation.
Two of the 70 class locos are preserved, 7007 and 7010 with 7006 and 7008 being preserved-operational.
The NSW 70 Class from IDR Models
DCC with Sound and Light Modifications
In September 2018, IDR Models released the NSW 70 Class Locomotive which includes an 8 Pin socket for fitting a DCC decoder.
In DCC the Headlights and Marker Lights will operate directional.
For this installation we recommend the ESU LokSound 5 (Sound) or the LokPilot V4.0 (No Sound) for those not wishing sound.
We offer DCC or DCC with sound including a Stay Alive Device to enable uninterrupted performance at super slow speeds especially travelling through insulfrog points.
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.
We offer a light modification for this 70 Class to separate the Red Markers for Shunting
The IDR 70 Class lighting inside the model allows us to separate the red markers from the rest of the lighting allowing for individual control resulting in you being able to have red markers on at both ends while shunting in a yard,
DCC Solutions Lighting
For an upgrade to 4 Function Standard Light Modification we can separate the lights as follows:
1) Front Headlight with White Markers - directional with the headlight button or on/off with 1 function button (Not Directional)
2) Rear Headlight with White Markers - directional with the headlight button or on/off with 1 function button (Not Directional)
3) Front Red Markers - on/off with 1 function button
4) Rear Red Markers - on/off with 1 function button
5) Directional operation for all lights.
The DCC Solutions 70 Class Custom Sound Project packed with sounds and features not found on other sound decoders
Others will only offer you the very basic sound or not the correct sound
So why not get fully featured sound from DCC Solutions
Our Custom 70 Class Sound Project now includes these great 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 sound will not stop your loco at speed step 0 or by trying to use the brake with the drive hold on. So watch out you don't crash your loco.
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 and the sound will exit and return to whatever speed is set when exiting.
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.
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.
While the factory fitted sound will only offer you 1-2 random sound, DCC Solutions will have up to 12 random sounds that will play when either the loco is stopping or moving as we have been doing for years in all our Custom Sound Projects.
Brake Squeal on Deceleration
Activate this function and when you reduce the throttle speed quickly your locomotive will slow up quicker than normal for a short period and you will hear the squeal of the brakes just like if you where to apply and release the brake.
And includes all these great features to make your IDR 70 Class drive and sound impressive.
- Caterpillar D397 Prime Mover Sound
- Short Blast and Playable Horn
- Random Start-up sequences including Automatic Hot or Cold Engine Start.
