New South Wales D set

what is it?

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.
