About the NSWGR 48 Class Locomotive


The 48 Class diesel electric locomotives were built by A.E Goodwin, Auburn for the NSW Government Railways in four production batches (or mark versions)  between September 1959 and October 1970. They were built under the ALCO DL531 model with the largest number of 165 units built for NSW, 44 units built for the South Australian Government Railways 830 Class which operated services throughout SA on the narrow, standard and broad gauge lines. A further 3 narrow gauge examples were purchased by Silverton Rail for use on the Silverton Tramway Line around Broken Hill.

 

There were four versions built for the NSWGR were:

  • Mark 1: 4801 – 4845 (September. 1959 to March 1962)
  • Mark 2: 4846 – 4885 (June 1964 to September 1965)
  • Mark 3: 4886 - 48125 (March 1966 to July 1968)
  • Mark 4: 48126 – 48165 (January 1969 to October 1970)


The NSWGR 48 Class was ordered to commence the conversion of branch lines to dieselisation and to see if branch line operating costs could be reduced. They became an immediate success and by the early 1960's the heaviest trains in NSW were being hauled by multiply 48 class locomotives. They later went on to become the backbone to the NSW Fleet.


As well as branch lines they operated both mainline and metropolitan services and were seen on every line in the state. Aside from a couple written off after accidents in the mid-1980s, withdrawals didn't commence until August 1994. Others have been withdrawn since and as at January 2014, 66 units still remained in service as an extremely simple and reliable locomotive capable of performing any duty. Of the other 99 units, 7 have been preserved, 29 stored, 63 scrapped.

DCC with Sound

In 1999 , Powerline released their upgraded model of 48 Class Locomotive and this version continued through to 2004. These upgrades included light stands built into the chassis to reduce body scorch caused by the 12 volt light bulbs and better fitment. some metal chassis modifications, an upgrade to the Mark 3 Mabuchi motor with modifications to the motor housing for a better fit and provide more ventilation for the motor and improved wheels and tyres.  Apart from these modifications, the 48/830 also received some body modifications and new liveries. 

Being an older release the model was obviously DC with not provision for DCC but is can be converted to DCC. 


For this installation we recommend the ESU LokSound Range of 8 Pin decoders, such as the LokSound V4.0 (Sound), LokSound Select (Sound) or LokPilot V4.0 (No Sound) for those not wishing sound. We offer several different options of DCC installation for this model to suit all budgets and can also supply decoders for the DIY Installers.


We have tweaked the motor control of the ESU decoder to provide super slow smooth speeds at steps 1-8 of 128 (Speed step 1 of 28), even on theses old models, 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 48 Class to convert the Headlights from 12 volt light bulbs to LEDs


The DCC Solutions NSW 48 Class Custom Sound Project - ALCo 6-251B
is packed with sounds and features not found on other sound decoders

Our Custom 48 Class locomotive 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 it can coast 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 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.

Remastered Horn Sounds
A new remastered NSWGR WABCo A/B Series playable and short blast horn
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 Powerline 48 Class drive and sound impressive
