KiwiRail will receive an extra $94 million in this year's Budget to help make its rail freight business self-sustaining.
Transport Minister Gerry Brownlee said the new investment, from the Government's future investment fund, followed $750m of investment in KiwiRail over the last three years.
KiwiRail will spend the $94m on new wagons and locomotives, and on track and infrastructure renewals.
Overall, transport spending in this year's Budget has increased by $15.4m in operating funding and $101m in capital funding.
That includes $14m for SuperGold Card public transport concession fares over the next two years, which will bring funding to $24m this year and $26m next year.
