Alstom has secured a €538 million (NZ$1.065 billion) contract to supply Wellington with 18 battery-electric multiple unit (BEMU) trains.
The announcement in mid-September marks the first deployment of BEMUs in New Zealand. The contract also covers 35 years of long-term maintenance, ensuring operational reliability. Regional rail operators anticipate the upgrade will improve service efficiency and sustainability.
Masterton Facility to Support Advanced Train Maintenance
The new fleet, to be deployed on the Wairarapa and Manawatu lines, will replace ageing diesel-hauled services from 2028–2029. The trains will be maintained at a purpose-built facility in Masterton, equipped with advanced servicing and battery management systems.
Modern, Low-Emissions Fleet
The five-car trains, branded Tūhono (“to connect” or “to unite”), will carry up to 475 passengers and operate at speeds of up to 120 km/h. Designed for comfort and accessibility, they will feature toilets, bike and pram spaces, water dispensers, and vending machines.
The fleet will run emission-free through non-electrified sections, including the 9km Remutaka Tunnel, thanks to onboard batteries. Māori design elements, led by Indigenous Design and Innovation, will be integrated into the livery following community consultation.
Industry Commitment to Sustainable Transport
Pascal Dupond, Alstom’s Managing Director for Australia and New Zealand, said: “This project will unlock a greener transport option for the people of Wellington. We are committed to delivering an environmentally friendly, modern and inclusive comfortable journey for every passenger.”
Ling Fang, Alstom’s Asia-Pacific President, called the deal “a clear testament to Alstom’s commitment to advancing sustainable mobility … bringing our zero-emissions rail technology to the Asia-Pacific region for the first time.”
Global and Local Significance
Alstom has sold 60 BEMU trains globally since 2020, including in Germany and Ireland. For New Zealand, the contract represents an important step in decarbonising transport while supporting local jobs through the Masterton servicing hub.
