In 2014 , six of the class were fitted with fire suppression to run passenger services through the Rimutaka Tunnel on the Wairarapa Line due to a change in requirements resulting from the Commission of Inquiry in the Pike River Mine disaster . This was removed from these locomotives in mid-2015 and reinstalled into the DFB class locomotives which took over the haulage of these services . However , fire suppression has been refitted to several members of the class in order to provide locomotives for passenger charter services and for back-up for The Great Journeys of New Zealand long-distance passenger services
