The rail link is operated jointly by the Swedish Transport Administration and Danish railways. Passenger train service is commissioned by Skånetrafiken and the Danish transport agency under the Øresundståg brand, with Transdev and DSB being the current operators. A series of new dual-voltage trains was developed, linking the Copenhagen area with Malmö and southern Sweden as far as Gothenburg and Kalmar. SJ operates X2000 trains over the bridge, with connections to Gothenburg and Stockholm. Copenhagen Airport at Kastrup has its own railway station close to the western bridgehead. Trains operate every 20 minutes, once an hour during the night, in both directions. An additional couple of Øresundstrains are operated at rush hour. Freight trains also use the crossing.
