The New South Wales H sets, commonly referred to as the OSCAR (Outer Suburban Car) trains, are a class of electric multiple units (EMU) currently operated by Sydney Trains on its intercity routes and some Sydney suburban routes. 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 second-class V set carriages (second class DCM and DCT carriages). As long-distance trains, the H sets share a similar overall layout and design to the previous Intercity Tangara G sets. Currently operating as 55 four-carriage sets, the H sets now operate between Sydney, Central Coast and Newcastle and between Sydney and the South Coast.
