New South Wales S set
class of electric multiple unit operating in New South Wales, Australia
The S sets are a type of double-decker electric multiple units (EMU) that formerly operated on Sydney's suburban rail network in New South Wales, Australia from 1972 up until 2019. Originally entering service under the Public Transport Commission, the sets also operated under the State Rail Authority, CityRail and Sydney Trains in later years.
The S sets were originally designated into three classes, two-car L sets (originally T sets), four-car S sets, and six-car R sets. Some received other designations when they were employed on local services on the South Coast and around Newcastle, becoming two-car PK sets and three-car NC sets respectively.
Prior to their retirement, the S sets were the last class in the Sydney Trains fleet to not be air-conditioned, earning them the nicknames "tin cans" and "sweat sets".
They were also nicknamed "Ridgys" because of their fluted ("ridged") stainless steel panelling; they shared this nickname with similar looking K sets and C sets. Their stainless steel appearance is shared with the intercity V sets and U sets. All remaining sets were withdrawn from service in June 2019.
Delivery
Two manufacturers built 509 carriages, based on a largely common design. They were based on the Tulloch Double deck power cars (C3801–C3804) and the numbers of the Comeng built motor cars would follow on from this.
This brief starts where responsible research should: with the source description of “New South Wales S set” as class of electric multiple unit operating in New South Wales, Australia. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as class of electric multiple unit operating in New South Wales, Australia. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 3, 2026. The linked authority identifier is Q5122982. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1972 and 2019.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
