A billion-dollar budget shortfall threatens to significantly disrupt Wellington's train services over the next few years.
A report by the Greater Wellington Regional Council identifies insufficient funding for maintaining capital's rail network.
It also identifies a large back log of maintenance programmes that KiwiRail has to deliver in the region.
Waka Kotahi, KiwiRail and Greater Wellington are jointly required to fund the network with the support of the Ministry of Transport.
Greater Wellington Regional Council chair Daran Ponter spoke to Corin Dann.
