It was a joint venture between Danish state railway operator DSB and British transport group FirstGroup.

[4] Oresundtrain services were operated from Helsingør and Nivå in Denmark along the Coast Line and over the Øresund Bridge to Malmö, Växjö, Kalmar, Karlskrona and Gothenburg in Sweden as well as extensive network of railways in Scania.

The company continued to operate DSBFirst Denmark's services without FirstGroup's involvement under the name DSB Øresund after December 2011.

[5] DSBFirst Sweden ceased operating the Swedish part of the Oresundtrain franchise after difficulties encountered by Danish State Railways over cross subsidization and accounting irregularities.

Due to the bad economy, the franchise was later awarded to SJ AB subsidiary Götalandståg, who have been operating the Västtåg and commuter rail services since 30 June 2012.
