Four trains per hour cross the
Øresund Bridge each way. Trains run at 15-minute intervals between via
Copenhagen in Denmark to
Malmö and
Lund in southern Sweden, increasing to six trains per hour during rush hours. From Lund, the trains continue hourly in three directions, to
Gothenburg, to
Kalmar and to
Karlskrona (the fourth train ends in Helsingborg). After midnight, traffic is reduced to one hourly train between Østerport in Copenhagen and Lund (the train between 01:00 AM and 02:00 AM starts from
Copenhagen H). Each train consists of up to three 79-metre-long units coupled together, each with 229 seats, providing a capacity of max 4122 seats per hour. This has turned out to be insufficient, as differences in salaries and house prices between Copenhagen and Malmö have resulted in an unexpected increase of cross-border commuting. The trains cannot be lengthened because of platform length constraints. And increasing frequency beyond six trains per hour is not possible because there are only two platform tracks to share with other trains at the stations , , and . Increasingly, people have to stand during rush hours, into Copenhagen in the morning and towards Malmö in the afternoon, which beside the inconvenience also raises safety concerns. The network at its peak covered of railway. In Denmark, the trains run on the
Boulevard Line and the
Øresund Line, between and the Airport in 10-minute frequency. In Sweden, they run through the
Malmö City Tunnel, and on the
Southern Main Line to Lund. From Lund, most Øresundståg services continue to either
Gothenburg,
Kalmar, or
Karlskrona, using the
West Coast Line, the Southern Main Line, the
Coast-to-Coast Line or the
Blekinge Coast Line. Passengers mostly encounter Swedish staff on the trains over the Øresund Bridge, but before 2023 there could be either Danish and Swedish staff. For travel inside one of the Swedish counties or inside Denmark, the local traffic authority tickets are used. For travel from Sweden to Denmark tickets can be purchased from the Swedish regional transit authorities and ticket sales channels which are part of the Resplus system, such as
SJ. Until December 2020, the trains were operated by
Transdev in Sweden and by
DSB in Denmark. In December 2020, Swedish rail operator
SJ Öresund, a subsidiary of the state-owned operator
SJ, took over the operations in Sweden. Due to an early cancellation of the contract with SJ as a result of differences in opinion regarding conditions for the rolling stock maintenance,
Transdev took over as a temporary operator for both operations in Denmark and Sweden in December 2022.
VR Sverige took over operations in December 2025. In December 2022 the Danish authorities left the Øresundståg operations, and from that time it is operated with Swedish responsibility only. At the same time Øresundståg stopped operating the route between Østerport and
Helsingør, which was taken over by DSB domestic trains.
Operation On 27 June 2007 it was decided that
DSBFirst was to assume responsibility from 2009 for the running of all Øresundståg services on the
Øresund Line and connected destinations. DSBFirst started operations on 11 January 2009. In 2011, the Danish and Swedish ministries of transport instructed DSBFirst Sweden to cease operating the Swedish part of the service from 10 December 2011
Veolia Transport took over the Swedish side and DSBFirst Denmark's services passed to
DSB Øresund. The Øresundståg operation has suffered from financial problems as well as delays and cancelled trains on both the Danish and Swedish part of its network, notably during the 2010 winter. On the Danish side the trains stop often, about every 4 km, like a
commuter train. On the Swedish side the trains stop much less often, more like inter-city trains, and they reach stations about 300 km from Copenhagen, such as Gothenburg, Kalmar and Karlskrona. Most travellers use it like a regional train for work commuting and similar shorter journeys, and local monthly passes are valid on the train. The combination of routes of an inter-city nature in Sweden with commuter-like routes in Denmark is often a source of trouble. The long-distance trains from Sweden often accumulate delays during the long journey. But delays cause trouble to commuter passengers having fixed work hours and not wishing to add long margins, since they travel every day. Therefore, some stand-by trains were ready at Kastrup that run to Helsingør if the train from Sweden was delayed. In these circumstances the train from Sweden terminated early and did not continue to Helsingør. Because of the complexity involved in the Øresundståg operation and the result of delays on the Danish side of the network, the decision was taken to split the operations in December 2021. The Danish services are now tendered by the Danish authorities, while
Skånetrafiken will be responsible for the tendering process for the international and Swedish services. The trains to Helsingør now start at
Holbæk or
Næstved. In 2023 a fourth circulation of Øresundståg was started between Helsingborg and Østerport due to demand and enabled by the opening of a new platform in Helsingborg, so that trains go once per 15 minutes instead of once per 20 minutes most of the day. ==Competitors==
