Auckland will gain ownership of 57 new electric trains in return for taking responsibility for repaying a $500 million Government loan over 35 years.
But the loan repayments will in turn be subsidised by the Government through the Transport Agency, starting at 60 per cent before reducing over 10 years to a new financial assistance rate of 50 per cent.
Transport Minister Steven Joyce confirmed the Government will also provide a grant of $90m to further sweeten a funding and ownership deal which he signed at Henderson railway station this afternoon with Auckland Mayor Len Brown.
Annual repayment costs of the loan will amount to about $34 million, with Auckland ratepayers paying about half of that.
Mr Brown expected the new electric fleet, to be introduced by the end of 2014, would lead to a doubling of existing patronage of 10 million passenger trips a year and put Auckland in pole position for further modernisation through a $2.4b central city rail tunnel.
