Øresundståg or Class ET in Denmark and X31K & X32K in Sweden is an electric passengertrainset in the flexliner-family operated by DSB, DSB Øresund, SJ and Veolia Transport in the transnational Øresund Region of Denmark and Sweden. The name is a hybrid of the Danish Øresundstog and the Swedish Öresundståg, both meaning "Øresund train". The maximum speed is 180 km/h.
Trains run at 20-minute intervals (hourly during the night) over the Øresund Line between Helsingør and Copenhagen in Denmark and Malmö and Lund in southern Sweden. From Lund most Øresundståg services continue to either Gothenburg, Kalmar, or Karlskrona. This schedule is augmented by a weekday service between Nivå and Copenhagen Airport, Kastrup with some rush-hour services continuing across the Øresund to Malmö and Lund, effectively giving a 10-minute frequency on the route between Lund and Copenhagen Central Station and even more frequent service between Helsingør and Copenhagen. The network thus covers route 854 kilometres (531 mi) of railway.
The trains are operated by DSB Øresund in Denmark and Veolia Transport in Sweden. Trains operated by DSB on the inter-city line to Ystad also run over the network, where they connect to the high-speed ferry to Bornholm. This connection (train + ferry) is considered to be a DSB inter-city service for ticketing purposes. The travel time to Bornholm has been cut in half (3 hours, as against 6 hours previously) since opening of the Øresund Bridge and the introduction of a high-speed ferry, making the combined service more competitive with air travel (35 minutes' flying-time plus 30 minutes' check-in time).
Passengers can encounter both Danish and Swedish staff on the trains over the Øresund Bridge. Tickets can be bought from either country and are valid on all trains. For travel inside one of the Swedish counties or inside Denmark, the local traffic authority tickets are used. For travel across county borders special Øresundståg tickets are used, which are sold by the local traffic authority at selected locations. Security guards accompany all trains after June 2012 following rising levels of threats and violence during ticket checks and sales.
Between Gothenburg and Malmö (until 2012 to Copenhagen, but not to Helsingør), SJ AB (the Swedish national railway) operates competing trains. From 2009 they have different tickets compared to the Øresundståg services. SJ runs X2000 trains via Hässleholm, and from 2009-2011 SJ ran intercity IC3 (X31) trains using via Helsingborg. Confusingly, the IC3 train type is often referred to as the "Öresundståg". Different tickets are needed. A similar situation is with the DSB trains to Ystad, which do not accept Øresundståg tickets despite the "Øresundstog" nickname often given to the rolling-stock used.
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 in Sweden use it like a regional train for work commuting and similar shorter journeys, and local monthly passes are valid on the train.
Three trains per hour in each direction use the Øresund Bridge, increasing to six trains per hour during the rush hour, each train consisting of up to three sets coupled together, creating 237-metre-long trains each with 588 seats, providing a capacity of 1764 (3528) seats per hour. Increasingly this has turned out to be insufficient, and people have to stand during rush hours (into Copenhagen in the morning and Malmö in the afternoon). The differences in salaries and house prices between Copenhagen and Malmö have made cross-border commuting more attractive. The trains cannot be lengthened because of platform length constraints. Earlier, the number of trains was limited to three per hour per direction, owing to the need to reverse at Malmö C which restricted capacity. This restriction has been removed by the opening of the Malmö City Tunnel in 2010. Still, some stations restrict capacity because there are only two tracks shared with other trains (mainly Triangeln, Kastrup Airport and Nørreport), so increasing frequency beyond six trains per hour is not possible.
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 DSBFirst nowadays have stand-by trains ready at Kastrup that run to Helsingør if the train from Sweden is delayed. In these circumstances the train from Sweden is terminated early and does not continue to Helsingør.
The trains used are the fourth and latest generation of the IC3 family of multiple units, specifically designed for use in regional traffic in areas connected by the Øresund Line. They are electrically powered, and can run on both the Danish power supply (25 kV 50 Hz AC) and the Swedish power supply (15 kV 16⅔ Hz AC) Named Contessa by its manufacturer Bombardier, they are designated Litra ET in Denmark and Littera X31K (where X means electric multiple unit, and K means allowed to go to Copenhagen) in Sweden. The chassis is manufactured entirely of stainless steel, painted in a light shade of gray. Roughly half of the trains are owned by DSB and the other half by Veolia.
Each trainset is 79 metres long and weighs about 157 tonnes. The trainset consists of three carriages, giving a weight of about 52 tonnes per unit. Eight of the train's 12 axles are powered, which gives good acceleration. The train's top speed is 180 km/h. Each train costs 67 million Swedish kronor (2006), equivalent to 22 million kronor per unit.
The train has a total of 196 seats (65 per carriage unit), of which some are in a low floor carriage in the middle.
The train type is nicknamed "Øresundstog / Öresundståg" (Danish / Swedish), but they are used not only for services on the Øresundståg network, but also for some local Scania traffic, for the DSB intercity trains Copenhagen-Ystad, and for some of SJ's Copenhagen-Gothenburg intercity trains. Even though these other trains do not in fact form part of the Øresundståg network, they are nevertheless often popularly referred to by that name.
The line numbers are used by SJ. They are not used by any Danish operator.
Today three trains, rush hour six per hour both ways run over the Øresund Bridge.
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.
