X 2000

X 2000, officially designated X2, is an electric high-speed tilting train operated by SJ in Sweden. It has a top commercial speed of 200 km/h (125 mph) and a top design speed of 210 km/h (130 mph) but has achieved a maximum speed of 276 km/h (171 mph) in tests. It primarily serves major routes, including Stockholm–Gothenburg and Stockholm–Malmö–Copenhagen. The X2 project began in 1969 as a collaboration between Kalmar Verkstad, Swedish State Railways (SJ), and ASEA. In 1986, SJ placed an order for 20 sets of a new type of train. Asea was responsible for manufacturing the electrical components, while Kalmar Verkstad (Statsföretag) was responsible for the mechanical design and manufacturing. Ultimately, a total of 44 train sets were built. The trains, designed and manufactured in Kalmar, Sweden, were launched in 1990 as a first-class only train with a meal included in the ticket price, and free use of the train's fax machine. From 1995 second class was introduced. The fleet has undergone various refurbishments over time, most recently ongoing since 2020.
