On 15 May 2008 Fonterra and Eastern Coal Holdings reached an agreement to continue to rail coal from Eastern Coal's Takitimu mining operations in the Ohai/Nightcaps district to Fonterra's Clandeboye dairy factory. Under this new contract, approximately 120,000 tonnes of coal will be carried annually by the Ohai line. After infrastructural upgrades such as a new rail load-out system were undertaken, the contract came into effect on 1 September 2008; to fulfil it, trainloads of up to 550 tonnes of coal leave the Branch daily. In 2011, KiwiRail undertook a refurbishment of the line with a large resleepering and bridge strengthening projects to allow larger, heavier, containerised coal trains to operate, while allowing for an increase in speed. This work was completed in late 2012.
