The S sets are a class of electric multiple units that operated on Sydney's suburban rail network 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. 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 was also shared with the intercity V sets and U sets. All remaining sets were withdrawn from service in June 2019.
