The NSW TrainLink fleet of trains serves the areas outside Sydney, Australia, mainly interurban and interstate lines. The NSW TrainLink fleet consists of both diesel and electric traction, with the oldest of the fleet being the V sets and the youngest being the H sets.

Interurban and outer suburban fleet

The network's interurban services are designed with extra facilities (such as armrests and on-board toilets) to cater for longer distance journeys connecting Sydney with regional centres. All interurban trains are air-conditioned.^{[citation needed]}

Electric

V set (1970–1989)

V sets form the backbone of NSW TrainLink's interurban services. They were manufactured by Comeng and were introduced between 1970 and 1989. They currently run in four or eight car configurations containing toilets on the Central Coast & Newcastle Line and the Blue Mountains Line to Lithgow.

H set (OSCAR) (2006–2012)

H sets (nicknamed OSCARs, for Outer Suburban CARs) were introduced from 2006 and operate as 4 or 8 car sets on the Central Coast & Newcastle Line and South Coast Line. The OSCARs were initially ordered to replace the G set Tangaras on outer suburban runs, however in addition to this they have also been used to replace some of the older interurban V sets which have been retired.^{[citation needed]} They contain toilets and feature suburban style 3×2 seating and perform some suburban only work in addition to their main outer suburban duties.

D sets (Mariyung) (2024–)

D sets (also called the Mariyung trains, previously the New Intercity Fleet) are currently being introduced, and will start carrying passengers in 2024. They will be operating on the Blue Mountains Line, Central Coast & Newcastle Line and South Coast Line,^[1] intended to replace V and H sets currently running on these lines, with some H sets re-allocated to suburban services and all V sets withdrawn.^[2]

Produced in South Korea by RailConnect, a joint venture of Hyundai Rotem, Mitsubishi Electric and UGL Rail,^[3] the first train was delivered in 2019, but the trains are expected to enter service in 2024 due to a safety-related dispute between the rail union and the government. The D sets feature non-reversible 2x2 seating (unlike other sets), phone charging, accessible toilets and dedicated spaces for luggage, prams, bicycles and wheelchairs.

Diesel

The network's diesel multiple units are run on the Southern Highlands Line, the far reaches of the South Coast Line (between Kiama and Bomaderry), services on the Blue Mountains Line that extend to Bathurst, and the regional Hunter Line.

Endeavour railcar (1994)

Endeavour railcars were introduced in 1994. The 28 carriages were manufactured by Adtranz.^[4] They serve all lines on which diesel trains operate. The New South Wales Xplorer is a long distance configuration of the same basic design.

Hunter railcar (2006–2007)

Hunter railcars are the newest members of NSW TrainLink's diesel fleet, serving the Hunter line only. Introduced between 22 November 2006^[5] and 10 September 2007,^[6] they replaced the old 620/720 railcars. Features of the series of the 7 2-car trains include air-conditioning, security cameras, on-board passenger information displays and digital voice announcements.^[5]

Regional and Interstate fleet

All of the regional and interstate fleet are diesel powered and are single deck trains.

Xplorer (1993–1995)

XPT (1981–1994)

CAF Civity (future)

Maintenance depots

The electric trains are tied to different maintenance depots. V sets are maintained at Flemington Maintenance Depot and H sets are maintained at UGL Rail Maintrain. D sets are maintained at Kangy Angy Maintenance Centre on the Central Coast & Newcastle Line. XPTs and Xplorers are maintained at the XPT Service Centre just south of Sydenham station. The future CAF Civity trains will be maintained at Dubbo Maintenance Centre.
