The Tangara (an Aboriginal word meaning to go) is a class of electric multiple unit operated by Sydney Trains in Sydney, Australia. The Tangaras were delivered between 1988 and 1995, and are third-generation trains.[1]

Design[edit]

A Tangara is a double-deck four-car set, with the two outer cars being driving control trailers fitted with one pantograph each and the middle two cars being non-control motor cars. They are equipped with air conditioning and chopper control.

Two subclasses of Tangara were built, the suburban sets targeted as T sets, and outer-suburban sets targeted as G sets. The T sets replaced the first generation of Sydney's electric rolling stock.[1]

Unlike most other CityRail trains the seats on the T sets are fixed, meaning that half the seats face backwards.

The G sets differed from the T sets in having yellow front panels, round green door buttons, high-backed reversible seats, toilets, fresh water dispensers and luggage racks.

Set G7 was fitted with an AC drive system for evaluation purposes with the existing DC stock and compatibility with signalling and communication systems on the network. G7 was scrapped in 2005 at Maintrain, Auburn after the Waterfall train disaster, as all four cars were beyond repair.

Delivery[edit]

In July 1986 the Government of New South Wales awarded A Goninan & Co a contract for 450 carriages.[2] In 1993 it was decided that the last 80 carriages of the order would be built to a modified design to operate peak-hour services on services to Wyong, Port Kembla and Dapto.[3] In 1996 five spare driving trailers were ordered.[4]

The first train was unveiled at Sydney Central in December 1987,[5] entering service in April 1988. The final T set was delivered in February 1994 and the final G set in October 1995.[6]

The cars built were:

T set driving trailer cars: D6101-D6284 with additional spare cars D6285-D6289
T set non-driving motor cars: N5101-N5284 with additional spare car N5285
G set driving trailer cars: OD6801-OD6840 with additional spare car OD6841
G set non-driving motor cars: ON5801-ON5820
G set non-driving motor cars with toilet: ONL5851-ONL5870

In service[edit]

When first introduced, the T sets were fitted with passenger door release handles to prevent loss of air conditioning at stations. These were later disconnected (and later removed) due to passengers not getting used to opening the doors for themselves when needed. The seats originally had fabric upholstery, but this was gradually replaced by blue vinyl. They were also fitted with front destination displays although these have rarely worked.

Since 2003, all Tangaras have been updated with a new CityRail corporate appearance. This involved the fitting of yellow panels on the front, yellow painted passenger doors and the end carriages receiving yellow paint surround for the benefit of visually impaired passengers.[7] Blue and yellow stripes along the bottom of the carriages were replaced by a single yellow stripe and new fuzzy CityRail logos were placed on the driving cars.

In 2010 a refresh of the Tangaras commenced with the interiors repainted, and new seating upholstery and handrails fitted.[8]

In July 2013 Sydney Trains rearranged the seating on the upper and lower decks on two carriages as a trial on the Western and North Shore lines, with 16 less seats, a 3x2 seats was replaced by 2x2 in one carriage while in the other carriage there are double seats on one side and a bench style seating on the other[9]

The following Tangara carriages have been scrapped due to accidents:

Driving Trailer Cars: D6114, D6127, D6274, OD6831 & OD6832
Motor Cars: N5127, ON5816 & ONL5866

The following are replacement carriages:

D6285 & N5285 are replacing written-off cars D6127 & N5127
D6286 is on set T99 (replacing written-off D6274)
D6287 is on set T73 (replacing written-off D6114)
D6108 is on set T16 (replacing D6241 for unknown reasons)
D6288 is on set T71 (replacing D6108 which is replacing D6241)
D6289 is on set T24 (replacing D6148 which is replacing D6106)
D6184 is on set T37 (repaired set back to normal)
OD6841 is currently used in Outer Suburban Tangara set G21 (replacing OD6807 for unknown reasons)
D6148 is on set T1 (replacing D6106 because D6106 has been stripped for parts)

Driving trailer car D6127 and motor car N5127 were both involved in the Wentworthville train derailment on 27 December 1989, Cityrail's first major accident involving the Tangara fleet. D6127 was written off, having collided with the platform. N5127 was sent to Dunheved on the Ropes Creek line for training fire fighters.[10]

Conversion of G sets to T sets[edit]

In February 2003 a contract was awarded to United Group Rail to construct 41 H set carriages (10 four car trains, plus 1 spare car). These new trains have a very similar level of passenger amenity to the G sets and can be seen as a continuation of the design. In April 2005 an additional 81 carriages were ordered.[11]

In late 2005 15 V set carriages were suddenly withdrawn due to the discovery of corrosion in their underframes. G sets began to operate more off-peak Intercity services to Port Kembla, Kiama, and Wyong to cover for the withdrawn V sets.

H sets started entering service in December 2006, leading to a change in the role of the G sets. From 2007 the G sets were progressively redeployed to suburban services, providing extra capacity on high-demand existing services such as on the Western line and allowing new services to be introduced. By 2008 G sets were often used on peak suburban services that extend into intercity areas, such as services to Springwood (via the Western line).

In 2009, the conversion of G sets to T sets began, to improve their suitability for suburban working as H sets took over their outer suburban duties. Conversion work consisted of the removal of toilets and their replacement with additional seating. Other work included the installation of new handrails and hangers and the recoding of cars and sets. G4 was the first to be converted (into T104). In 2010 sets being converted started receiving a full refurbishment.

Lines serviced[edit]

The Tangaras usually operate on the following lines. Since 2013 their operation on Sector 2 has ended timetable services with all of them being displaced to Sector 1 since A sets do not operate on that sector. These are the following operations:

4D[edit]

A train bearing strong resemblance to a Tangara, known as the 4D, was built by A Goninan & Co in 1991 for the Public Transport Corporation.[12] Although outwardly similar to the Tangaras it was mechanically very different being built to be compatible with the Comeng trains operated in Melbourne. It was included in the sale of Hillside Trains to Connex Melbourne in August 1999. It wasn't successful and after spending large periods out of service, being withdrawn in December 2002 and stored at Newport Workshops. The 4D was bought by CityRail for parts before being scrapped in March 2006 at Sims Metal, Brooklyn.
