The first of the new Mariyung fleet train chugged from Kiama to Central this morning – a major milestone for the 136-year-old rail line

The South Coast commute just got a glow-up. This morning, the first passenger service of the brand-new Mariyung train fleet rolled out of Kiama Station at 7.56am, bound for Sydney’s Central Station – marking a long-awaited milestone for Illawarra travellers who’ve spent years watching this upgrade inch closer to reality.
While the inaugural journey is a headline moment, the real win is what’s coming next. Later this year, commuters between Wollongong and Sydney can expect trains every 15 minutes during peak hour (a noticeable jump from the current three-per-hour situation), alongside a new timetable that promises smoother, more frequent services across the board.
According to the NSW Government, these trains are built for the long haul – literally and figuratively. The Mariyung fleet (already chugging between Sydney and Newcastle) is the first new intercity rollout in nearly two decades, designed with the reality of extended commutes in mind. Passengers can expect roomier two-by-two seating, proper tray tables for working on the go, USB charging ports, high seat backs and quieter, air-conditioned carriages. There’s also space for luggage, bikes, prams and wheelchairs, plus upgraded digital screens and CCTV for improved safety.
The rollout on the South Coast Line will happen in phases, starting with a handful of four- and six-car sets this month, before expanding to longer eight- and ten-car trains by 2027. It’s all part of a broader push to modernise the network and improve reliability – something anyone who’s endured a peak-hour platform delay will appreciate.
The upgrades will generally make life easier for commuters, but there are a few changes to keep in mind. Under the new timetable (landing later this year), South Coast services will run to and from Central only – meaning no more direct trips to Bondi Junction. If you’re heading further east, you’ll need to change at stations like Hurstville, Sydenham or Redfern. Similarly, stops at Wolli Creek will eventually be scrapped, with airport-bound passengers needing to transfer instead.
Still, for most South Coast regulars, this is a net win. The 136-year-old rail line – one of the most scenic in NSW – is finally getting the kind of vehicles to match its rep. And for the thousands who make the daily trek from the coast to the city, it might just make that early alarm a little easier to face.
