Auscision XPT - DCC and Sound Installation

with Lighting Modifications

Bring your XPT to Life with a Sound Project like no OTHER.

The XPT (Express Passenger Train) is the main long-distance passenger train operated on country rail services in New South Wales from Sydney to Dubbo, Grafton and Casino as well as interstate destinations, Melbourne in Victoria and Brisbane in Queensland. The XPT is based on the British Rail designed HST (High Speed Train) and entered service in April 1982.

In January 1978 the Public Transport Commission invited tenders for 25 high-speed railcars. In August 1979 Comeng was announced as the successful bidder after submitted a tender for a train based on the British Rail-designed High Speed Train. The High Speed Train design was significantly modified, compare to its British counterpart, with the power cars being 50 cm shorter, the Paxman Valetta engine downgraded from 2,250 to 2,000 bhp (1,680 to 1,490 kW), gearing lowered for a top operating speed of 160 km/h, the suspension modified to operate on inferior track, and air filters and the cooling system modified to cater for hotter and dustier Australian conditions. A different light cluster was also fitted along with three high-beam spotlights mounted to the roof.

On a demonstration run to Albury on 6 September 1981 the XPT set a new Australian speed record of 183 km/h between Table Top and Gerogery in Southern NSW. Then a year later during a run to Albury on 18 September 1992 the XPT broke its own record by reaching 193 km/h.

The initial XPT livery was red, black and orange with InterCity XPT signwriting on the power cars.

In February 1990, the Brisbane Limited and Pacific Coast Motorail were withdrawn and replaced by XPT services to Brisbane and Murwillumbah.

In November 1993. XPTs replaced locomotive hauled stock on the overnight Sydney/Melbourne Express then in December 1994 an XPT daylight service to Melbourne was introduced by extending the Riverina XPT from Albury.

During 2002 the original Paxman Valetta engines were replaced with the V-12 Paxman VP185

In 2015, the NSW Government allocated $7.5 million to start planning for a new fleet to replace the XPTs

In September 2015, Auscision released the NSW XPT passenger train as a  7 Car Set (2 x Power Car & 5 x Passenger Cars) which includes a 21 Pin socket for easily fitting a DCC decoder plus a speaker enclosure that suits a 20x40mm speaker in both Power Cars meaning two decoders are needed for DCC operation. There are micro switches under the Power Cars for turning lights on/off in DC.In DCC all lights, (including the strobe lights on the roof) will operate directional.The DCC Decoders require additional programming than usual to be able to run the power cars and lights in the correction direction the train is travelling.

For this installation we recommend the ESU LokSound V4.0 (Sound) programmed with our Custom Sound Project or the LokPilot V4.0 (No Sound) for those not wishing sound. 

The DCC Solutions Custom V-12 Paxman Sound Project packed with sounds and features like no other sound offering.

The NSW XPT Custom Sound Project includes:

  • Paxman VP185 V12 Prime Mover.
  • The Leading and Trailing Power Cars programmed with their own sound schedules.
  • Cold and Hot Engine Starts.
  • Random start up and shut down sequences with the sound project remembering how it shut down to play the corresponding start up.
  • Dual Power Car start up and shut down or start up and shut down each power car individually then run as one unit.
  • Coasting on Demand. Put either or both Power Cars into coasting with the trailing car entering service mode.
  • Hear the correct sounds from each of the Power Cars depending on the direction of travel with our extensive programming setup.
  • Short Blast and Playable Horns
  • Two Tone Country Horn with working Strobe Lights
  • 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.
  • Random Speed Sensitive Rail Clanking (Set up for a 7 car set) and Rail Noises when the loco moves off.
  • Electro-Pneumatic (EP) Braking
  • Stop & Drive Random Sounds with more sound options to make your XPT not always sounding the same each time its run.
  • Guard's Whistle Pack. A selection of Guard's Whistle selectable with CV48.
  • Optional Light Modifications to control all the lights individually or the usual all on at once.
  • High Beam Headlight Function allowing you switch the headlights from low beam to high beam and back.
  • Motor settings and sound volumes tuned to specifically suit the Auscision XPT Passenger Train.
  • Both Power Cars speed matched to provide more consistent running speeds between the cars.
  • Master sound volume can be adjusted by the user allowing you to go louder or softer to suit personal requirements.
  • Your XPT will sound different each time you run it, to provide more realism than hearing the same sounding loco all the time.

    Here at DCC Solutions we offer a light modification for the XPT Passenger Train to separate the headlights, white and red marker lights, ditch lights and the roof strobe lights for a more prototypical operation in DCC.We can separate the lights on this model by upgrading the ESU 21 Pin Decoder (4 Functions) to 6 Function lighting outputs with the DCC Solutions 2 Function Power Amplifier.

    The marker lights can be controlled individually as well as the headlights, ditch lights and strobe lights.Remember the real XPT didn't run with all the lights on at once all the time.

    The strobe lights are functioned to operate when the short blast or the high/low horns are operated and will remain flashing after the sound of the horn until you turn the function off. Actual working Low/ High Beam Headlights are also a feature rather than the usual dimmer function.

    Also our Sound Project now includes Move Off and Stopping Sounds so before your XPT starts to move you will here the brakes air release then some speed sensitive wheel rail clanking (which has been designed and setup for the 7 Car Set to provide the right amount of sound) and rail noises until you reach specific speeds then will turn off automatically. When the loco slows to a stop you will hear the squeal of the brakes, air release and then the compressor will cut in to fill the reservoir and will turn off when the tanks are full.

    All this to add to the realism of sound.

    These are all automatic sounds programmed into our Custom Sound Project and can be disable using F28.
