SJ 2000

X 2000, also called X2, is a tilting train operated by SJ in Sweden. It was constructed by Kalmar Verkstad in Kalmar, Sweden (prior to the company being bought by Adtranz in 1996) and 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. There is a bistro on board that serves snack bar-style dishes.

The trains were initially used sparingly to avoid electrical breakdowns. From 1995 the trains were used more intensively and second class was introduced.

"X2000" was originally a brand name for a number of train connections with a certain service level. Generally the X2 train is used, but because of lack of vehicles, sometimes (especially in the year 2009/2010) other train types have been used, like X40 or Rc loco-hauled stock. These connections were called X2000 on the tickets anyway. Since December 2011, all high speed services of SJ using X2 or X55 trains are called "SJ Snabbtåg" or "SJ High-speed train".

The train's designated top speed is 210 km/h (130 mph). It reached 276 km/h (171 mph) during a trial run with double locomotive units in 1993. However, the maximum speed allowed in regular traffic is 204 km/h (127 mph) for safety reasons – the signal system (and systems like the catenary) are not built for more, and it shares the track with regular trains; also, most of the lines it uses were built in the mid to late 19th century. The 19th century railways Stockholm-Gothenburg/Malmö are relatively straight, since they were planned the shortest way without taking intermediate cities into account, and the landscape is relatively flat. Other 19th century railways are generally curvier. In comparison to other high-speed trains, the X2000 is not particularly fast; but compared to regular train services, it cuts journey time by about 25% – enough to make it competitive with airlines on many routes. It typically averages about 150 km/h (93 mph). The fastest part is Katrineholm–Skövde, a distance of 180 km (110 mi) that is covered in 1h 2min, resulting in an average speed of 174.2 km/h (108.2 mph).
