The government says rail freight uses 66 % less carbon emissions compared to trucks. 

Yesterday, the first train in six years travelled along the Napier-Wairoa railway line. 

The move is part of the government's wider plan to open the line and shift logs by rail by the end of the year. 

Forestry Minister Shane Jones says the $5 million investment will take close to 6,000 trucks off the road. 

The government says it'll create more job opportunities for the Tairāwhiti region - 49% of whom are Māori.
