The Sydney Trains A set or Waratah is a class of electric multiple unit trains operated by Sydney Trains in Sydney, New South Wales, Australia. The train was named Waratah by the NSW Government after the flower of the same name, which is the state's floral emblem.

The design is based on the M set and is the largest rolling stock order in Australia's history. The 626 carriages make up around half of the Sydney Trains fleet, and replaced two-thirds of the 498 S set carriages. Delivery commenced in July 2011 and was completed in June 2014.

Public Private Partnership[edit]

The carriages were delivered by a joint venture between Downer Rail and Hitachi for Reliance Rail under a Public Private Partnership (PPP).[1] As part of the PPP, Reliance Rail will also maintain the trains for a minimum of 30 years at a purpose built facility at Auburn.[2] At least 72 sets must be made available to Sydney Trains every day during the contract period.

Reliance Rail took on debts of $2.4 billion at cheap interest rates before the global financial crisis.[3] Higher interest rates and changes in the financial sector after the GFC meant the company would have difficulty refinancing its debt, leading the Government of New South Wales into talks with Reliance Rail to resolve the financial status of the project.[4] In February 2012 the Government agreed to bail out the project for $175 million by becoming the sole shareholder in 2018.[3][5][6]

Design[edit]

The sets are formed of eight carriages – a break from the previous standard Sydney practice of four car sets, which are then coupled to form eight car trains. The configuration is: trailer driving car + motor car + motor car + trailer car + trailer car + motor car + motor car + trailer driving car.[1] This means that guards operate from the rear of the train rather than the centre and that commuters are able to walk through the entire train in an emergency. Nightshine Australia was selected to produce luminescent arrow signs line, which are affixed on the base of outer seats on the lower and upper decks to direct passengers the most appropriate route of exit.[7] The trains include external CCTV cameras to assist guards.[8]

The train's guards' compartment is located in the last carriage

Inside, the train includes additional Emergency Help Points and CCTV cameras. Thales Australia was awarded the contract to design the train's extensive system of 98 CCTV cameras, Digital Video Recorders, Guard video display units, passenger information displays, emergency intercoms, audio servers, PA systems and hearing loops, which are linked together with Power over Ethernet. The audio and communication system supplied by Open Access Pty Ltd included 8 channels of audio per car with extensive DSP to optimize audio quality and intelligibility. The Hearing Loop system was a world first Class-D based amplifier and utilised 3 loops per car. Hearing loop coverage exceeded 90% of the vehicle. The CCTV cameras supplied by Axis Communications utilise Progressive scanning technology to allow capturing of events in clear high resolution, with no distortion in quick movement individual frames.[9] The CCTV cameras are designed to withstand vibration and features technologies such as an in-built heater to prevent condensation and alarms to alert of removal or obstruction.[10] The train flooring utilises Treadmaster TM8, made from a polymer-based material that is designed to be durable, vandal and graffiti resistant. They are also designed with safety in mind, being highly fire resistant with low smoke toxicity output.[11] Carriage interiors were designed by Transport Design International [12]

Improvements to the DVAs (Digital Voice Announcements) with differential pitch of the voice allow more natural sounding speech. All the stations included in the stopping pattern are also announced prior to or soon after departure from a terminus stop. ‘Smart’ air-conditioning automatically adjusts to the outside temperature and the number of passengers on board.[13] Accessibility features include 16 wheelchair spaces, portable wheelchair ramps in the end cars, red fabric on priority seating and additional handrails compared to older trains in the fleet.[8]

The A set is the first passenger train in the world to use LED lamps for all lighting (except headlights).[14] Woollen moquette fabric, a durable, vandal-resistant material first used in the OSCAR trains, Hunter Railcars, and later adopted in the refurbishments of both the Tangara and Endeavour railcars, is used to cover the train's seats.[14] Detailed design of the train was completed in July 2009.[15]

Construction and delivery[edit]

The joint venture between Downer EDi Rail and Hitachi was established to design, manufacture and commission the trains.[1] The stainless steel bodies are partially constructed by Changchun Railway Vehicles in China before being shipped to Downer EDI’s Cardiff Locomotive Workshops facility for final assembly, testing and commissioning.[1] The manufacturing facility at Cardiff received an upgrade of over $20 million to cater for the needs of the project.[1] Other infrastructure works included the construction of a maintenance facility at Auburn and new substations at various locations around the network.[16]

A four car pre-production test train was built to test the train sub-systems and compatibility with the Sydney suburban network.[1] This was intended to allow any issues with the train to be corrected before the production trains entered service.[1] The test train was expected to perform trial runs from mid 2009,[1] but did not begin network testing until April 2010.[17] The pre-production train concluded testing in August 2010.[18] The first production set began network testing in August 2010[18] and by November 2010, three sets were undergoing testing.[19]

The first trains were scheduled to be introduced in late 2010, but a series of delays pushed back their introduction.[20][21] The first train intended for service (A3) was delivered to then-operator CityRail for acceptance on 20 April 2011.[22] CityRail had 20 business days to accept or reject the train, but a decision was postponed by two weeks to allow Downer EDi to correct further defects.[23] CityRail rejected the train due to safety concerns and a number of defects.[24] The defects included; 'Milky' effect windscreens – apparent when under direct sunlight, no padding in the carriage ceilings, cables obstructing the driver's view, poor-quality steel welding as evident in the indents seen on some areas of the carriage exterior, gaps in the plastic moulding, handrails not lining up with stairs and software problems.[6][25]

Once the majority of the problems were resolved by Downer EDi, CityRail allowed A3 to commence service, though operating under special conditions.[26] It entered service on 1 July 2011,[27] operating its maiden run from Redfern to Macarthur via the City Circle and Airport. Initially, it operated two return services from the City to Macarthur via the Airport line during the off-peak period on weekdays, and all day on the Airport & East Hills and South lines on weekends. On 14 October 2011, A3 became the first Waratah set to operate during peak hours.[28] As more Waratahs became available, the trains were progressively rolled out to most lines of the Sydney suburban network. On 2 June 2014, the State Government announced the final Waratah set (A80) had been delivered.[16]

In service[edit]

Originally the Waratahs were intended to replace all 498 S set carriages,[29] but in February 2013 it was revealed that some S sets would still be required in order to provide services on the South West Rail Link.[30] An option existed to extend the order but in March 2013 the government indicated it would not take this up.[31]

In May 2014, the State Government announced its intention to purchase around 520 new carriages for the NSW TrainLink intercity network, with deliveries to commence in 2019. These new trains will release at least some H sets from intercity services, allowing them to be transferred to Sydney Trains to replace the remaining S sets.[32]

Formation[edit]

The 626 carriages form 78 eight car sets (numbered A1, A3 to A78 and A80)with 2 spare driving cars. Individual vehicles are numbered as follows:

  • A1: D6301-N5301-N5501-T6501-T6601-N5601-N5401-D6401
  • A3: D6303-N5303-N5503-T6503-T6603-N5603-N5403-D6403

up to

  • A78: D6378-N5378-N5578-T6578-T6678-N5678-N5478-D6478
  • A80 (Former A2): D6380-N5380-N5580-T6580-T6680-N5680-N5480-D6480

The two spare driving cars are D6379 and D6479. These were the first vehicles delivered, along with N5342 and N5442, and are part of the four car testing and development train.

The first 40 sets were delivered to CityRail with a Waratah logo on each carriage. Following the formation of Sydney Trains in July 2013 these were replaced by the Sydney Trains logo and the sides of the driver's cab covered in orange vinyl.

The A sets currently operate on these lines:
