SJ 2000

200 km/h (120 mph)

SJ 2000 (previously X 2000) is the brand name of Sweden's tilting high-speed train class X2, which was constructed by Kalmar Verkstad in Kalmar, Sweden (prior to the company being bought by Adtranz in 1996) and operated by SJ. It was 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 breakdowns. From 1995 the trains were used more intensively and second class was introduced.

The train's designated top speed is 210 km/h (130 mph) (but during a trial with double locomotive units in 1993 it reached 276 km/h (171 mph), but the maximum allowed speed in regular traffic is 204 km/h (127 mph) since the signal system (and systems like the catenary) are not built for more for safety reasons, and as it shares the track with regular trains and as most of the lines it uses were built in the mid to late 19th century. The 19th century railways Stockholm-Göteborg/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).

In 2000-2004, seven trains were operated by Linx on the lines Oslo-Gothenburg-Malmö-Copenhagen and Oslo-Stockholm. Linx was a joint venture between SJ and its Norwegian counterpart NSB. It was wound up when SJ wanted to move the trains to more profitable lines in Sweden. Low-fares airlines also played a part in siphoning off passengers from the comparatively slow Linx services, the main ones taking well in excess of three hours.

All trains are equipped with wireless LANs for passenger access to the Internet and were repainted grey as of 2005. The trains also have electric power supply sockets at all seats in both first and second class. The trains have been fitted with repeaters to improve mobile phone reception.

X2000 was 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, relatively often (especially year 2009/2010) other train types are used, like X40 or Rc loco-hauled stock. These connections were called X2000 on the tickets anyway.

Since Dec 2011, the high speed services of SJ using X2 or X55 trains are called "SJ Snabbtåg" or "SJ High-speed train".
