IDR Models X200 Class DCC Sound Installation
with Stay Alive

Released February 2016 - Installations Now Available

The X200 class were a class of rail tractors introduced in 1963 and operated by the New South Wales Government Railways of Australia. They were a development of the smaller and less numerous X100 class. The X200 class remained in service until 1990 when they were either withdrawn or sold off to private companies, and some remain operational today.

Mark 1 series

The Mark 1 series of the X200 class were 3 times more powerful and twice as heavy as the X100 class. Six were built and numbered X201-X206.

They were built using a number of steam locomotive spare parts using the inner bogies of the AD60 Beyer-Garratt class locomotives, and used spare C36 class locomotive windows in their cabs. Their engines were rated at 190 kW at 2,100 rpm and had a top speed of just 39 km/h.

The addition of a train brake allowed them to be run on the main line and also to be used as replacements for various ageing shunting locomotives. X201 was the first of the class entering service in December 1963. The six Mark 1s were initially used in the Sydney metropolitan network, but did later find their ways beyond this region.

Mark 2 series

The Mark 2 series of the X200 class were different again. Twelve were built and numbered X207-X218.

They were built on the outer bogies of the AD60 Beyer-Garratt class locomotives. Their engines were more powerful rated at 220 kW at 2,100 rpm and they had a higher top speed of 51 km/h. This made them more practical for light line use.  The exterior design of the Mark 2 was squarer, giving it the appearance of a baby-brother to the 49 class diesel locomotives.

The first six were built in 1967. The second six being an additional order, were placed into traffic from May 1968, with the final member of the class entering service in December 1968. Despite differences in engine horsepower ratings, both variants were rated as having a tractive effort of 17,750 lbf (79.0 kN). This was more powerful than many of the typical small and workshop steam shunting locomotives of the time.

The X200 class must be considered largely successful, as they began to replace the various ageing steam shunting locomotives in various depots of the time. They were cleaner, more efficient to run, requiring less maintenance, and also giving locomotive crews more comfortable working conditions. Another indicator of the class success is that several examples are still operational even today, at an age of around 45 years!
In February 2016, IDR Models released the Mark 2 Series X200 Class Shunting Locomotive which includes an 8 Pin socket for fitting a DCC decoder. In DCC the Headlights will operate directional. No Marker Lights are fitted to the model.

For this installation we recommend the ESU LokSound V4.0 (Sound) or the LokPilot V4.0 (No Sound) or the TCS (Train Control Systems) DPX2-UK for those not wishing sound.  

We offer DCC or DCC with sound including a DCCS PowerPlus Stay Alive to enable uninterupted performance at super slow speeds especially travelling through insulfrog points.

YES... We have been able to fit a sound decoder, speaker, and stay alive inside the body of this tiny model without using the cab space. Simply Amazing!!!
.....and sounds equally impressive!!!

The DCC Solutions X200 Class Custom Sound Project packed with sounds and features!

Our Custom Sound Project is now available

The NSWGR X200 Class Custom Sound Project includes:

Two new features have been added to our Custom Sound Project. Coasting on demand and a working Independent Brake.

Coasting on Demand
This feature allows you to enter coasting mode whenever you what with a press of a button.Often when coming to a stop, the throttle of a real locomotive is put into Idle and the engineer coasts to a stop. Another situation that occurs is that once a train is up to speed when operating over
rolling terrain, the engineer can coast to maintain a certain speed. By pressing the coast function button, the sound drops from wherever you are to idle and remains there. Using the throttle speed control, you can now speed up or slow down the train with the sound remaining constant, at idle.
Press the function button to exit coasting and the sound will exit idle and return to whatever speed is set when exiting.
Independent Brake
Simply press the Independent Brake Function button and your loco will come to a stop at a much short distance than if you were to bring the loco to a stop by reducing the speed throttle.Press the function button to release the brake and your loco will move off again.

Plus these great features:

  • Cummins 6 Cylinder Prime Mover
  • Coasting On Demand
  • Working Independent Brake.
  • Short Blast and Playable Horn.
  • Random Start-up sequences.
  • 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.
  • Separate Coupling and Uncoupling Functions
  • Stop & Drive Random Sounds including, compressor, rail noise, track wheel squeal, air releases
  • Wheel Flange Squeal
  • Guard's Whistle
  • Low beam/High beam Headlight.
  • Motor settings and sound volumes tuned to specifically suit the IDR Models X200 Class Locomotive Model.
  • Super Slow Speed performance perfect for shunting.
  • Individual master sound volumes can be adjusted by the user to suit personal running requirements.
  • Full 28 function button remapping to suit your personal requirements.
  • DCC Solutions PowerPlus Stay Alive to enable uninterupted performance at super slow speeds especially through insulfog points.
  • DCC Solutions "MICRO" High Performance Dynamic Speaker which is only 4mm high with enclosure inside the body and not the cab.
  • Here is the selection of sound and function labels using the ESU V4.0 sound decoder
