In May 2019, DKB and the RATH Group won the largest transport contract ever awarded in Germany, containing bus routes amounting to more than 8 million kilometres. The contracted service, which starts on 1.1.2020 under the name Rurtalbus, is the continuation of a partnership between the District of Düren and the RATH Group. The two partners have already worked together on the Rurtalbahn rail network for over 15 years. Awarding the contract to the bidding consortium means that these long-standing partners can now offer a coordinated transport concept from a single source. The ambitious bus service tender, offering extra provision of 1.2 million bus kilometres and 100 bus lines, enables not only an improved local transport system but also the implementation of more innovative transport concepts, thus equipping the city and the district of Düren for future challenges ahead.
