Labour MP Phil Twyford has come upon a document within KiwiRail that gives cause for concern about the rail network's maintenance. It suggests that despite $750 million National has put into KiwiRail as part of a $4.6 billion "turnaround plan", the asset will decline after 2014 and that the following year track renewal will be halved.
Projects on the main line will be cancelled or deferred, the condition of sleepers will deteriorate and less will be spent on timber bridge maintenance, among other things.
At least this time Labour did not raise the spectre of privatisation, as it did when KiwiRail's value was drastically written down at the end of June, and again last month when the company announced the first job cuts. The railway is unlikely to be sold again as it is now constituted - with trains and tracks in the same entity.
Its period in private ownership proved fairly conclusively the railway is not an economic proposition. Two private operators were unable to make it pay for the estimated value of the network. TranzRail was accused of running down the asset before it sold the operation to the Toll Group, which was unable to pay the access charge required when the Labour Government re-nationalised the land and tracks.
Under Labour, the whole operation was valued at $10.6 billion, which might reflect its replacement cost but not its ability to earn a return. Under National its value has been written down to no more than $1.3 billion, on which it will be expected to show a normal commercial return. Both figures are important to answering the basic economic question: is it still worth our while to maintain a railway?
