negotiations did not progress and eventually went to arbitration at the start of 2008. Renationalisation (2008–current) Instead of concluding a final track access agreement with Toll, in 2008 the government purchased the rail and ferry assets for $690 million, effective 1 July 2008. The new organisation created to operate services on the rail network was named KiwiRail. Ownership of the national rail network is vested in KiwiRail Holdings Limited, with land owned by the New Zealand Railways Corporation. KiwiRail Network (formerly ONTRACK) is a division of KiwiRail that maintains and upgrades the rail infrastructure and is responsible for the control of the network (i.e. train control and signalling). Other rail operating companies using the rail network include Auckland One Rail and Transdev Wellington, who operate suburban services in Auckland and Wellington respectively, and Dunedin Railways, who operate tourist trains out of Dunedin. KiwiRail released in 2010 a 10-year turnaround plan for the rail industry. This was accompanied by significant government investment in KiwiRail of over $2.1 billion during the period 2008 to February 2017. In May 2017, the government announced a further $450 million capital injection and that KiwiRail would be subject to a further significant review. The plan has been significantly undermined by the Christchurch earthquakes of 2010 and 2011, the 2016 Kaikoura earthquake, Pike River Mine disaster, coal price collapse, coal miner Solid Energy going into voluntary administration in 2016 and major motive power issues with the new DL class of locomotives. Nevertheless, significant improvements in freight volumes have followed (other than with coal). Two of KiwiRail's major customers, Mainfreight and Fonterra, also invested heavily in rail-related infrastructure. Mainfreight allocated $60 million for investment in new railhead depots, while Fonterra invested $130m in a new rail hub complex in Hamilton and another planned for Mosgiel. New Zealand Rail Plan In 2019, the government began a "Future of Rail" review, and in December 2019 released a draft New Zealand Rail Plan, outlining changes to the rail transport industry. The draft plan proposes a number of major changes, the most significant being future funding of the rail network through the National Land Transport Fund (NLTF). The final plan was launched in April 2021, confirming funding for rail projects from the NLTF, and the use of Track Access Charges (TACs) for users of the rail network, including KiwiRail. Some specific projects were also outlined as possibilities: Reopening the Stratford–Okahukura Line; Completing
