Whanganui exporters will benefit from a KiwiRail project beginning later this year.
Alan Piper, KiwiRail group general manager of sales and commercial, told the Chronicle work would start in late 2018 on the upgrade of the Whanganui-Castlecliff rail line.
Funding of $3 million for the project was announced in February by Regional Economic Development Minister Shane Jones in the first round of Provincial Growth Fund grants.
"KiwiRail estimates that each year the project will keep 6250 trucks off the road and 563 tonnes of carbon dioxide out of the atmosphere by enabling freight to travel by rail," Mr Jones said at the time.
Mr Piper said KiwiRail had got the Castlecliff line back up and running in partnership with Castlecliff industries, including Open Country Dairy and Ali Arc, and Wellington's CentrePort. It allowed KiwiRail to run services from the Castlecliff industrial area through to Wellington.
