DSBFirst is a railway company that commenced operating the Oresundtrain rail franchise from Helsingør and Nivå in Denmark along the Kystbanen line and over the Øresund Bridge to Malmö, Växjö, Kalmar, Karlskrona and Gothenburg in Sweden in January 2009. It was a joint venture between Danish state railway operator DSB and Scottish transport group FirstGroup. FirstGroup had a 25% shareholding in the Danish business and 20% in the Swedish business. By March 2011 this was 30%.
In December 2011 DSBFirst ceased operating the Swedish part of the operation after difficulties encountered by Danish State Railways over cross subsidies.
