The 1960s were marked by an increasingly poor economy for DSB, leading to a steady staff reduction throughout the decade. However, this was also accompanied by the appearance of new technology, notably the utilisation of electronic equipment, improving the safety and efficiency of DSB's railway traffic. In 1972, along with the celebration of the 125th anniversary of railways in Denmark, DSB introduced a new corporate design by architect Jens Nielsen, inspired by British Rail and Canadian National Railways, with red as the dominant colour (with engine rooms of locomotives painted black), replacing the traditional maroon livery with yellow winged wheel symbols. DSB's position was additionally strengthened by the 1973 oil crisis.
