The Regina is a Swedish electric multiple unit passenger train produced by Bombardier Transportation (formerly known as Adtranz). It operates in both national and regional sectors under various operators such as SJ, UL, Västtrafik, among others. The train comes in models ranging from X50 to X55 (branded as SJ 3000), available in two-, three-, and four-car sets. Engineered primarily for local and regional transit, the Regina features a broader car width of , which allows seating arranged five across, resulting in a 25% increase in passenger capacity.
Built using stainless steel with titanium substituting molybdenum to prevent surface corrugation, these trains vary in length from to meters and provide seating accommodations for between 165 and 294 passengers. The design of the Regina also served as the foundation for the China Railways CRH1 series.
Their operational velocity spans from to km/h during regular service, with a maximum design speed reaching up to km/h. Under the Gröna tåget ("green train") program, a modified X52 unit achieved a Swedish rail speed record of km/h in 2008, with the goal of supporting consistent operation at speeds of km/h.
X55, new high-speed train
In late 2007, SJ placed an order for twenty X55 units (marketed under the name SJ 3000) intended for inter-city travel. These four-car trains were delivered between 2011 and 2012 and serve routes linking Stockholm to Sundsvall, Karlstad, Oslo, and Falun. Their introduction allowed older X 2000 trains to be redeployed to increase capacity on heavily trafficked lines toward Gothenburg and Malmö. The X55 includes first-class seating options, an onboard bistro, and seating arranged four across. There is also a possibility to procure an additional twenty units.
