The New Zealand DM class[nb 1] of 66[1][4] diesel-electric locomotives are currently under manufacture for New Zealand rail operator KiwiRail by Stadler Rail in Spain. The locomotives are expected to be introduced between 2024 and 2026.[2]

Background

[edit]
Model of a DM class locomotive

In March 2020, KiwiRail released a tender for new mainline locomotives to replace the 47-strong DX class,[5] which were nearly 50 years old at the time. The 2021 New Zealand budget allocated NZD$722.7 million to purchase new mainline locomotives, shunt locomotives and wagons.[6]

On 11 October 2021 Stadler Rail announced it had won the contract to supply 57 new locomotives for KiwiRail.[7] Stadler stated the contract was worth €228 million,[7] or NZD$403 million.[2][8] The Rail & Maritime Transport Union, the main union representing KiwiRail staff, welcomed the purchase.[9] The company had previously won a contract to supply 34 similar locomotives to the Taiwan Railway Administration in 2019.[10][11]

In February 2024, KiwiRail and Stadler announced an order for a further nine DM class locomotives equipped with European Train Control System (ETCS) technology for deployment on the North Island rail network.[4] The last ten locomotives from the first order will also be fitted with ETCS, bringing the total number of ETCS-fitted DM class locomotives in the North Island to 19. ETCS will enable the locomotives to operate in the Auckland metro area, which is fitted with ETCS Level 1 signalling, and future proofs the class to safely operate in the Wellington metro area once trackside signalling there is upgraded to ETCS.

Classification and numbering

[edit]

KiwiRail has stated the locomotives will be classified as class "DM".[3] The original impression of the design showed the numbering to be in the 10,000 series. Mock-ups of the locomotive cab show numbers in the 6000 series, which has not been used since the withdrawal of the DQ and QR class locomotives.[12] It was reported in late 2022 that the design phase had been completed, and the first locomotives are now in production, to be completed in mid-2024.[13] As of November 2023, the class numbering is in the 8000 series.[14]

Production, testing and entry into service

[edit]

KiwiRail posted a video on their Facebook page on 8 February 2024 of the prototype locomotive at the Stadler manufacturing plant in Spain. The short clip shows one of the new DM locomotives running on a factory track under its own power. The post stated that the first two locomotives will join the KiwiRail fleet later in 2024.[15]

The first two locomotives, DM8012 and DM8029, were unloaded from the Eemslift Nadine at the Port of Lyttleton in Christchurch on 19 October 2024.[16] They were described as the prototypes and will be commissioned at the KiwiRail Middleton Depot and undergo six months of in-service trials.[17][18]
