What was the operator of Sydney Trains T set from Jul 2013 to Jul 2014?
Sydney Trains T set The T sets , also referred to as the Tangara trains , are 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 . Design . The Tangara is a double-deck four-car set , with the two outer cars being driving control trailers ( carrying a D prefix [ driving motor car ] ) that are fitted with one pantograph each and the middle two cars being non-control motor cars ( carrying an N prefix [ non driving motor car ] ) . All sets are equipped with chopper control . Unlike most other Sydney Trains rolling stock , the seats on the suburban T sets are fixed , meaning that half the seats face backwards . Former G sets , however , do have reversible seats . History . Initial delivery . In July 1986 , the Government of New South Wales awarded A Goninan & Co a contract for 450 carriages . 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 to Wyong , Port Kembla and Dapto . In 1996 , five spare driving trailers were ordered . The Tangara name is of Aboriginal origin , meaning to go Two subclasses of Tangara were built , the suburban sets targeted as T sets , and outer-suburban sets originally targeted as G sets . The T sets replaced the first generation of Sydneys electric rolling stock . The G sets differed from the T sets in originally having round green door buttons , high-backed reversible seats , toilets , fresh water dispensers and luggage racks . Additionally , the G sets were delivered with a revised design at the front and rear of the train , most notably the pinstriped grey panels below the cab windows were replaced with light orange panels for improved visibility . Another distinctive difference is the front curving back in underneath the coupler which is still the same to this day and visible in the photo beneath on the right . Another difference is the number plate on the front and back of the train with all the t sets having a number below one hundred and all the g sets having a number one hundred or above . The first train ( set T20 ) was unveiled at Sydney Central in December 1987 , heavily promoted as the “train of the 21st century” , entering service on 28 January 1988 . The final T set ( set T59 ) was delivered in February 1994 and the final G set ( set T100 , formerly G32 ) in October 1995 . The cars built were : 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 . Upgrades in the early 2000s . 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 . In the early 2000s , all Tangaras were updated with a new CityRail corporate appearance . This involved painting the passenger doors and much of the front and rear ends of the trains yellow . Blue and yellow stripes along the bottom of the carriages were replaced by a single yellow stripe and updated CityRail logos were placed on the driving cars . 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 . The newer trains feature a very similar level of passenger amenity to the G sets and can be seen as a continuation of the design . Their introduction lead 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 extended into intercity areas , such as services to Springwood ( via the Western line ) . Conversion of G sets to T sets . 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 . The carriage numbers were kept , however the O ( outer suburban ) prefix was dropped . OD became D , while ONL and ON became N . The set numbers were changed from G1-30 to T100-130 . G4 was the first to be converted ( into T104 ) . In 2010 , sets being converted started receiving a full interior refurbishment as part of the program to refurbish all the Tangara carriages . In 2018 , sets T14 and T121 ( ex G21 ) both became mixtures of T set and ex-G set carriages , with both sets swapping two carriages with each other . Upgrades in the 2010s . In 2010 , a refresh of the Tangaras commenced with the interiors repainted , and new seating upholstery and handrails fitted . In July 2013 , Sydney Trains trialled rearranging the seating on the upper and lower decks of two carriages . There were 16 fewer seats per carriage ; 3x2 seats were replaced by 2x2 seats in one carriage ( N5134 on set T78 ) while in the other carriage ( N5131 on set T77 ) there are double seats on one side and a bench style seating on the other . Both carriages were later returned to the normal 3x2 arrangement . In 2014 , phase one of a technology upgrade program , aiming to improve reliability and upgrade ageing components , was underway . A contract for phase two of the program , aiming to extend the life of these trains and bring technology into line with newer trains was awarded to UGL Limited in August 2015 . This was expected to be completed by July 2018 . The expected completion date has been revised to 2019 . The first phase of the program involved upgrading the passenger doors to cut down on vandalism , as the steel panels on the original doors were prone to being kicked out by vandals . The door kicking incidents often led to unnecessary delays as the guard had to lock off the affected carriage . The new lightweight passenger doors have a similar design to the doors on the Millennium M sets , namely the window shape with the curved bottom . This phase of the project was completed at the end of July 2016 . The first set to receive the new doors was T96 , in October 2014 . The program includes overhauling air conditioning units and windscreen wiper units , replacing passenger side doors , train operating systems and drivers desks . Other anti-vandal improvements included the introduction of Mousetrap sensors . Trialed in 2015 , these sensors are able to detect vapors from strong permanent markers and spray paint ; triggering an in-built camera feed which is relayed to Sydney Trains staff as well as the Police Transport Command . Service . Damaged carriages . The following Tangara carriages have been scrapped due to accidents : The following are replacement carriages : Driving trailer car D6127 and motor car N5127 were both involved in the Wentworthville train derailment on 27 December 1989 , the 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 , along with S Set car C3866 . Lines serviced . The Tangaras usually operate on the following lines : - T1 North Shore & Western Line : Emu Plains to City via Parramatta , City to Berowra or Hornsby via Gordon - T4 Eastern Suburbs & Illawarra Line : Bondi Junction to Waterfall & Cronulla via Hurstville & Sutherland - T7 Olympic Park Line : Lidcombe to Olympic Park - T9 Northern Line : Gordon to Hornsby via Strathfield - South Coast Line : Waterfall & Thirroul to Port Kembla 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 . Occasionally , as required , they will operate on other suburban lines , as all drivers are trained for Tangaras . Tangara Technology Upgrade Phase 2 . In May 2019 , Tangara sets T106 ( Ex G6 ) and T72 were released for testing the new technology upgrades , which include internal information screens , external destination boards and new voice announcements , both automated and digital . As the program is running late , four 4-car sets have been removed from service to accelerate the program , which requires one 8-car T set roster on Sector 3 to be operated by an extra Waratah A set . The project was due for completion by the end of 2020 , however , this target will not be met , since none of the upgraded Tangaras are in service as of 9 September 2020 . The full list of features added to the Tangara trains is as follows : Incidents . Carriage pierced by guard rail . During evening peak on 15 January 2014 , motor car N5222 on set T10 was pierced by a guard rail near Edgecliff railway station while on a service to Cronulla . Issues with the train were already developing on the previous run , triggering wheelslip sensors on the train multiple times . As the train entered the Eastern Suburbs Line , a strong burning smell was reported at several stations . It was later revealed that an incorrectly repaired axle on N5222 led to the force of the 440-tonne train picking up the piece of guard rail . Loose roof hatch . Just after 5 AM on 23 August 2019 , set T50 blocked a critical line near Town Hall station due to a loose roof hatch on driving trailer car D6223 , believed to have been damaged by a falling tree branch the night before . The roof hatch was dangerously close to the overhead electrical lines , and so power had to be isolated before moving it . This led to serious delays throughout the entire train network that disrupted both the morning and evening peak . Roads throughout Sydney were also blocked due to not coping with replacement buses . 4D . 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 . 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 wasnt 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 and then scrapped in March 2006 by them at Sims Metal , Brooklyn Victoria . The G sets cab ends have a design similar to the 4D , with the bottom part being bent inwards . External links . - T set technical diagrams Transport for NSW - G set technical diagrams
