Danish State Railways, known in Danish as Danske Statsbaner (DSB) was founded on October 1, 1885, when the railway companies of Jutland/Funen and Zealand merged on April 1, 1893. The 1930’s were a decade of innovation and modernisation, new railway bridges, the suburban lines in and around Copenhagen were electrified, and early experiments with diesel propulsion were carried out. The Second World War left DSB with a fleet of outdated and worn out trains, forcing the company to look for foreign suppliers. The 1960’s were marked by an increasingly poor economy for DSB, leading to staff reductions throughout the decade. However, there was also the appearance of new technology, with the utilisation of electronic equipment, improving the safety and efficiency of the company’s rail traffic. In 1972, along with the celebration of the 125th anniversary of railways in Denmark, DSB introduced a new corporate design, inspired by British Railways and Canadian National Railways, with red as the dominant colour and engine rooms of locomotives painted black.

The privatization reform of Denmark in the 1990’s resulted in the selling and outsourcing of many railway lines and services across the country. The company’s headquarters are located in Copenhagen and is now a public state-owned corporation under the Danish Ministry of Transport and Energy managing passenger rail service, including the operation of railway stations.
