About the NSW 47 Class Locomotive
The 47 class are a class of diesel-electric locomotives built by A Goninan & Co for the Public Transport Commission in 1972/73. Twenty were ordered with the first delivered in July 1972. After undergoing acceptance trails the first entered service in September 1972 with the last delivered in May 1973. Originally intended for use hauling coal services in the Hunter Valley, they were allocated to Bathurst to operate services in the state's west from Lithgow to Euabalong West, Bourke and Cootamundra and all branches in between. Their excellent ride qualities saw them find favour with crews, although they did suffer from overheating.

In January 1981 it was decided to transfer the class to Broadmeadow to take up the duties they had originally been built for being used to haul coal services from Belmont, Dudley, Lambton and Pelton. They also saw use on services to Werris CreekTamworth and Moree. They continued to return to Bathurst Workshops for overhaul. A downturn in traffic as a result of a drought saw them placed in storage at Parkes in 1982/83 before all were reactivated in 1984 resuming duties out of Broadmeadow.

In April 1974 the first locomotive was withdrawn from service and scrapped as it was destroyed by fire and another in a collision in March 1977. Then, 4719 was withdrawn from service in 1987 and stored at the Bathurst Workshops as a source of parts to keep other units working, later being joined by 4715 in November 1988. Despite their favouritism with crews, their high maintenance costs saw them selected for withdrawal in 1989 with only six in service or under repair by November 1989. The last being taken out of service in December 1990.

In 1990 the Lachlan Valley Railway purchased 4701 and 4708 followed in February 1994 by 4702, 4703, 4707 and 4716. A later purchase was 4717. These were used to operate wheat services in the Cowra region in 1993/94. In June 1999 they commenced operating trip working services between Port Botany and the Cooks River container terminal in Sydney for Lachlan Valley Rail Freight followed in July 1999 by a service between Cooks River and Carrington for R&H Transport Services. Five Lachlan Valley Railway units remain in service, primarily operating infrastructure trains for Southern Shorthaul Railroad. Disposition of the 47 class is as follows: 10 Scrapped, 4 Operational, 3 Stored, 1 Preserved, 1 Static, 1 Under Restoration


DCC with Sound

In November 2006, Trainorama released the 47 Class Locomotive which includes an 8 Pin socket for fitting a DCC decoder plus a factory installed 16 ohm speaker. The model has operating 1.5 volt incandescent bulbs for headlights which in DC/DCC will operate directional . 

We suggest replacing the factory speaker for improved sound performance and replace the incandescent bulbs to LEDs


For this installation we recommend the ESU LokSound V4.0 (Sound) with our Custom Sound Project for the 47 Class or the LokPilot V4.0 (No Sound) for those not wishing sound.  We offer some different 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 47 Class Custom Sound Project packed with sounds and features not found on other sound decoders

Our Custom 47 Class Sound Project now includes these new 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

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.

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.

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 it's speed to allow for 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.
And includes all these great features to make your Trainorama 47 Class drive and sound impressive.

Plus these great features:

  • Caterpillar Prime Mover Sound
  • Short Blast and Playable Horn - NSWGR Nathan P5
  • 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
  • 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.
  • Brake Squeal on Deceleration that slows up your loco.
  • 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!
  • Wheel Squeal
  • Guard's Whistle
  • And more (See below for full list)
