Rolling stock used for Sydney Trains' Intercity services
The D sets, also referred to as the Mariyung trains, are a class of double-decker electric multiple units (EMU) that operate on Sydney Trains intercity lines in New South Wales, Australia. Built by Hyundai Rotem, the trains currently operate on the Central Coast & Newcastle Line, Blue Mountains Line and the South Coast Line. The D sets replaced the former V set fleet, and will allow for the reallocation of the entire H set fleet to Sydney's suburban line services once all sets are introduced into service. The first trains were delivered in December 2019. After a protracted dispute between the government and the drivers' union over their safety, they entered service on 3 December 2024 on the Central Coast & Newcastle Line. On 13 October 2025, the D sets also entered service on the Blue Mountains Line. On 14 April 2026, the D sets also entered service on the South Coast Line.
