The NSW TrainLink D sets, also referred to as the Mariyung trains, are a class of electric multiple units (EMU) being built to replace NSW TrainLink's Intercity EMU fleet. The trains will operate on services from Sydney to Newcastle, Lithgow and Kiama, allowing the retirement of NSW TrainLink's V set fleet, and freeing the H set (OSCAR) fleet for reallocation to Sydney suburban services.
The first trains were delivered in December 2019. After a protracted dispute between the government and the drivers' trade union over their safety, the first are scheduled to enter service in late 2024/early 2025.[2][3]
