Wellington's new rail operator says major changes are coming as it takes over the city's trains this weekend.
State-owned KiwiRail was last year shunted as the operator of Wellington's regional rail service in favour of international company Transdev, which started its 15-year contract yesterday.
Its managing director, Niclas Flodin, said the company was now looking to bring in longer trains, starting with the Kapiti line.
"Longer trains will be introduced once the full fleet of Matangi units is here and operational," he said.
Along with new uniforms for staff, the company says it's also going to spend the next few months improving customer service, including with a new centralised base of operations.
"At the heart of the operation will be our new service control centre at Wellington Station due for completion before the end of the year," Mr Flodin said.
He said integrating the service with buses and introducing a single ticketing system over the next few years would also improve the quality of the service.
The Greater Wellington Regional Council last year said all of the 400 staff working on the services would keep their jobs as part of the new contract, although a "very small number" were excluded.
Transdev also runs Auckland's trains.
