World War II
The outbreak of World War II creates serious trade barriers. The situation is exacerbated by the German occupation of Norway and Denmark in the spring of 1940. Rail transport becomes crucial to get food and heating fuel to the cities.
The role of the railway in wartime
The Swedish military has great transport needs. In the event of mobilisation, it is important to be able to quickly transport military units around the country. There must be effective cooperation between the military and the railway. The realisation of the significant role that the railway plays in ensuring that society continues to function in times of crisis is an important lesson learned after World War II. The Home Guard unit SJ Driftvärn is therefore created.
