New South Wales T set
class of electric multiple unit operating in Sydney, New South Wales, Australia
The T sets, also referred to as the Tangara trains, are a class of double-decker electric multiple units (EMU) that operate on the Sydney Trains network in New South Wales, Australia. Built by A Goninan & Co, the sets entered service between 1988 and 1995, initially under the State Rail Authority and later on CityRail. The T sets were built as "third-generation" trains for Sydney's rail fleet, coinciding with the final withdrawals of the "Red Rattler" sets from service in the late 1980s and early 1990s. The Tangaras were initially built as two classes; the long-distance intercity G sets and the suburban T sets, before being merged after successive refurbishments. As of June 2026, the Tangaras are the oldest active electric trains in the fleet, following the temporary suspension of the K sets.
Design
The Tangaras are arranged in double-deck four-car sets, with the two outer cars being driving control trailers (carrying a D prefix) that are fitted with one pantograph each and the middle two cars being non-control motor cars (carrying an N prefix). All sets are equipped with Mitsubishi Electric 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 or refurbished G sets, however, do have reversible seats.
History
Initial delivery
The SRA called for tenders in 1985 for the manufacture of the next generation of Sydney's double-deck suburban trains.

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q5122983. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1988, 1995, 2026 and 1985.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
