With more than 8 million bus kilometers, the DKB and the RATH Group won the largest transport contract ever advertised in the Federal Republic of Germany in May 2019. The offer, which started on January 1st, 2020 under the name Rurtalbus, is the continuation of a cooperation between the district of Düren and the RATH Group. By awarding the contract to the bidding consortium, the long-term partners are now in a position to offer a coordinated transport concept, with bus and train, from a single source. The ambitious bus tender with an additional service of 1.2 million bus kilometers and 100 bus routes makes it possible, in addition to an improved local transport offer, to implement more innovative transport concepts that prepare the city and district of Düren for future challenges.
