The NSW TrainLink H sets, also referred to as the OSCAR (Outer Suburban Car) trains, are a class of electric multiple units currently operated by NSW TrainLink. Built by UGL Rail in Broadmeadow, the H sets first entered service under the CityRail brand in December 2006, with the last in December 2012. Their introduction allowed for the retirement of some V set carriages (DCM and DCT).^[1] As long-distance trains, the H sets share a similar overall layout and design to the previous G sets. Currently operating as 55 four-carriage sets,^[2] the H sets now operate between Sydney, Central Coast and Newcastle and between Sydney and the South Coast.
