First Great Southern rail service passes through Murray Bridge

A new passenger train has passed through Murray Bridge on its maiden journey - but this one does not stop.

The first Great Southern departed Adelaide on Friday morning, bound for Brisbane via the Grampians, Canberra and Coffs Harbour.

The inaugural run carried 214 passengers in 28 cars, stretching 711 metres long.

It will return via Coffs Harbour, Newcastle, Melbourne and the Twelve Apostles.

But unlike the Overland - the Adelaide to Melbourne service due to close on December 31 after the withdrawal of a taxpayer subsidy - the new service will not pick up or drop off passengers in regional areas.

Friday's train only came to a brief halt at Murray Bridge Railway Station to pick up a piece of electrical equipment, as a handful of onlookers snapped photos.

As with Journey Beyond Rail Expeditions' other remaining services, chief operating officer Luke Walker said, the Great Southern was more of an experience in its own right than a mode of transportation.

"Excursions will allow guests to truly explore beyond the tracks and be immersed in the towns, cities and landscapes the train passes through," he said in a statement.

"Guests will indulge in regionally inspired and carefully curated menus and be looked after by a team that goes above and beyond."

The Standard is seeking comment from state MP Adrian Pederick about the withdrawal of the subsidy to the Overland, the last remaining passenger rail service accessible to Murray Bridge residents.
