The "glass train" refers to the TranzAlpine, operated by Great Journeys New Zealand. It is world-renowned for its "Scenic Class" carriages, which feature massive panoramic side windows and unique glass roof skylights designed to provide an unobstructed view of the Southern Alps. The journey travels between Christchurch and Greymouth, traversing the Canterbury Plains and climbing through the rugged mountain passes. In 2026, the experience has been further elevated with the Scenic Plus class, which includes a dedicated carriage with even better viewing angles and locally inspired gourmet dining served at your seat. For those who want to feel the alpine air, the train also includes an open-air viewing carriage, allowing passengers to step outside the glass and take photos without any reflection or barrier between them and the spectacular scenery.
