Third weekly night train to Vienna from this winter

Brussels' new night train connection to Vienna has proved so popular that it will run more frequently from this winter, Austrian rail operator ÖBB has announced.

The twice-weekly NightJet service to the Austrian capital has been fully booked since it launched on 19 January. It currently runs on Monday and Thursday nights from Brussels. Trains leave Vienna on Sunday and Wednesday nights.

"It was a good decision to roll out this service," ÖBB spokesperson Bernhard Rieder told La Capitale. The train also calls at Liège, Munich, Nuremberg and Passau.

From December, an extra return journey will be added to the timetable, bringing the frequency to three times per week.

Since its launch, ÖBB has advertised return ticket prices from €29, for a seat with no bed. A berth in a shared compartment starts at €49. A private room costs €89.

But an investigation by Radio 2 found the cheapest advertised rates were almost impossible to find.

"There is a lot of demand for tickets and so the prices are higher," the Austrian rail operator said in a statement, promising a new batch of cheap tickets would go on sale later this spring.
