On 4 April 2011, a fire broke out on a Di 8 locomotive at Kløfta on the Trunk Line while hauling a 16-wagon train of jet fuel to Oslo Airport, Gardermoen. The fire started in an electrical cabinet after a diesel pipe running over it had cracked. The fire fighting was complicated by the train dispatcher not wanting to disconnect the overhead wire power as he thought it was an electric train. The damages were so severe that the locomotive was scrapped. The Accident Investigation Board Norway criticized CargoNet for not having sufficient maintenance routines for diesel pipes, as they were neither part of the maintenance procedure nor where there specified intervals for replacement.
