 At the break-out of World War II in Norway on 9 April 1940, all the company's buses were taken over by the armed forces.From 17 May, the buses were returned to the company, but quotas for petrol were introduced, and the company was forced to install wood gasifiers on its fleet.Both Steinkjer and Namsos were bombed in 1940, but in both towns the company's facilities survived, except the garage in Steinkjer.
