New carriages allowing for the ultimate passenger viewing experience will get their first run on the TranzAlpine service this morning.
The carriages feature 52 sq m of glass giving panoramic views around the side and through the roof, as well as HD screens and GPS triggered commentary.
KiwiRail General Manager of Passenger Services Deborah Hume says the new carriages will provide an even greater experience for the passengers.
"It's outrageous how much glass there is," she said. "All completely safe, engineering tested, but it's more glass than you can imagine actually."
The new carriages mark 25 years since the service between Christchurch and Greymouth began.
