X 2000, also called SJ X2 or simply X2, is an electric high-speed 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. From 1995 second class was introduced. All trains are equipped with Wi-Fi 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.

It has a top commercial speed of 200 km/h (125 mph), but has reached 276 km/h (171 mph) in a test. The reason the X2 was chosen was that Sweden (like most other countries) has very curved railways, and not enough traffic to justify building special high-speed railway lines (at least before 1990). As a result, a Swedish tilting train had to be developed. A tilting train provided the advantages of high speed and comfort for the passengers, as tilting trains can run through sharp (short radius or tight) curves up to 15% faster than non-tilting trains. The X2 was designed and built by ABB. SJ ordered 20 sets in August 1986 and planned to order a further 30. In the end 43 sets were built for SJ while one was built for the Guangshen Railway Company, China.

X 2000 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 2009/2010) other train types have previously been used, like X40 or Rc loco-hauled stock. After the introduction of the X55 in 2012 to replace the X2 on smaller routes such as Stockholm-Sundsvall, other train types are very rarely used on these lines. Since December 2011, all high speed services of SJ using X2 or X55 trains are called SJ Snabbtåg (lit. "SJ High-speed train").

Speed

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 power car units in 1993. The maximum speed allowed in regular traffic is 200 km/h (125 mph) for safety reasons – the signalling system (and systems like the catenary) are not built for higher speeds, and it shares the track with regular trains (like in most countries); 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 X 2000 is not particularly fast; but compared to regular train services, it cuts journey time by about 10–15% – enough to make it competitive with airlines on many routes. It typically averages about 150 km/h (95 mph). The fastest part is Katrineholm–Skövde, a distance of 180 km (110 mi) that is covered in 1 hour and 2 minutes, resulting in an average speed of 174.2 km/h (108 mph).

SJ considered configuring the trainset with a sixth trailing car and creating a set of 12 trailer cars using a second power car. The trainset can stop in 1.1 kilometres (0.68 miles) from a top speed of 200 km/h (125 mph).

Former lines and services

• 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.
• Briefly in 2010–2011 X 2000 trains ran once daily between Stockholm and Odense.
• In 2012–2013, when SJ received its X55 trains, X 2000 services were suspended on a number of routes and reduced on others.
  • One example is Stockholm–Sundsvall, with one daily departure, calling at Arlanda, Uppsala, Gävle, Söderhamn, Hudiksvall and Sundsvall. This route formerly used a single X 2000 trainset until it was replaced with X55.

Current lines and services

• Stockholm–Gothenburg, calling at Södertälje Syd, Katrineholm, Hallsberg, Skövde, Herrljunga, Alingsås and Gothenburg. Not all trains call at all stations. Since 2015 VR Snabbtåg Sverige (formerly MTRX) has competed with SJ on this route and Flixtrain since 2020.
• Stockholm–Oslo, calling at Södertälje Syd, Katrineholm, Hallsberg, Degerfors, Kristinehamn, Karlstad and Arvika before crossing the border to Norway, calling at Kongsvinger and finally Oslo S. From December 2018 onward, the X 2000 trains to Oslo have been temporarily replaced with loco-hauled stock and X55 Bombardier Regina express electric multiple units due to track work in Norway. A few X 2000 trains are used in services towards Karlstad.
• Stockholm–Malmö, with many trains continuing to Copenhagen, calling at Södertälje Syd, Norrköping, Linköping, Mjölby (occasionally), Nässjö, Alvesta, Älmhult (occasionally), Hässleholm, Lund and Malmö. Services to Copenhagen also call at Copenhagen Airport, Copenhagen Central Station and Østerport (usually). For a short period during 2010–2011, there was one daily train to/from Odense.
• Gothenburg-Malmö, where one of the daily round trips uses the X 2000.

2008 new high-speed trains

In 2008 SJ ordered 20 X55 Bombardier Regina trains to replace the X 2000 on lines with lower demand and where its performance cannot be fully utilised (especially on lines north of Stockholm such as the Botniabanan). When these trains were delivered in 2012 and 2013 the X 2000 trains could be concentrated to fewer lines with bigger demands such as Stockholm–Malmö/Copenhagen and Stockholm–Gothenburg, using double-length X 2000 between Stockholm and Gothenburg during rush hours and weekends.

Renovation

In January 2014, SJ announced that it was to invest 3.5 billion SEK in the modernisation and repowering of its X 2000 fleet, in order to extend the life of the trains by 20–25 years. SJ stated that the refurbishment of the trains would cost one third of the price of replacing them with new trains, whilst also having a reduced environmental impact.

ABB, whose predecessor ASEA designed and built the trains, were awarded the contract to replace the trains' traction converters, transformers, battery chargers, train control systems, and passenger information and entertainment equipment.

Additionally to the technical improvements, the new refurbished X 2000s feature a new livery with a dark grey front, as well as a rebuilt interior with new seats allowing for 15% higher seating capacity, new walls, ceilings, floors and lighting, and a rebuilt bistro. The new interiors were awarded a Red Dot Design Award in 2020, with the jury stating:

"With its perfectly harmonised colours and materials, the interior for the SJ X2000 high-speed train creates a particularly pleasant atmosphere. The elaboration in detail and the lighting concept create a peaceful ambience in the train compartment."

The refurbished trains were originally scheduled to start introduction in 2019, however the first refurbished set started operation in November 2021.

Effect on the railway

The train has had a major effect on SJ and the country's railway. More passengers, together with the lower operating costs associated with operating trains faster and more efficiently, helped SJ become profitable.

It also proved to Swedes that rail is a viable solution not just in exotic densely populated foreign countries, but also at home in Sweden. In 1991, the Swedish government started a massive investment program, spending 5–10 billion kronor annually on improvements to the rail network. The program continues today. A milestone was reached in the late 1990s when the number of trips taken by train in Sweden exceeded the 1940s level for the first time.

New links built since 1990 include the Øresund Bridge, the Arlanda Airport link, Södertälje–Huddinge, Söderhamn–Enånger, Varberg–Kungsbacka and Helsingborg–Lund. The X 2000 train contributed to building public support for these large projects.

However, between 2000-2008, the Stockholm-Malmö routing became increasingly congested due to an increase in traffic on that routing - a mix of fast express trains, slower stopping trains and freight trains - to the point that the fastest 2008 services averaged 21min longer than the fastest 2000 services.

Exports

The manufacturer of the X 2000 had tried to sell the train to countries other than Sweden, but with little success. In connection with the sales attempts the train was tested and demonstrated in some countries. Norway, Finland, Germany, Austria, France, China, Australia, Portugal and the US were mentioned as candidates.

An X 2000 toured the United States in 1992–1993 on lease to Amtrak. It was tested by Amtrak from October 1992 until January 1993. It was used in revenue service on the Northeast Corridor between New Haven, CT and Washington DC, via New York City, for about five months, from February until May and from August until September 1993. From May until July it was taken on a national tour around the 48 continental states for demonstration stops at significant stations. It also toured parts of Canada.

In 1995, three X 2000 cars (SJ2819, SJ2620 and SJ2520) were hired by Australian operator CountryLink for evaluation purposes, being one driving trailer, one bistro car and one first class car. The trains were towed in a push/pull mode by modified XPT power cars XP2000 and XP2009. After conducting a statewide tour of New South Wales in March 1995, they were used on Sydney to Canberra services from April to June 1995. The X2 was also tested in Norway and Germany. There were competitors which had lower prices, including Pendolino and ICE T.

The Guangshen Railway Company in China leased and later purchased outright an X 2000 train which it named Xinshisu (New Speed). The train served as Guangzhou–Kowloon through train from 1998 until 2007 when it was replaced by the Regina-based CRH1. The train was initially supposed to have been given the number 2044, but due to the fact that the number "4" sounds similar to the word for "death" in the Chinese language, it was renumbered as 2088, of which the number "8" symbolises luck in Chinese culture. It was delivered to Sichuan Province in August 2007. Due to the 2008 Sichuan earthquake, Chengdu Railway Bureau needed to rebuild the railway networks in Sichuan Province. Also, the authority could not carry the maintenance costs of the train. It was therefore returned to the Guangshen Railway Company in late December 2008. In 2012 the train was purchased by SJ and repatriated back to Sweden. The train had some serious damage and deferred maintenance. The cab car (110986 CUB2XFK) has been cosmetically restored and repainted, losing its Chinese livery, and will be displayed at the Swedish Railway Museum when it reopens. The power car (2088 CX2) is currently used as a testbed for the ongoing refurbishment program, and the five intermediate trailers were repaired and re-entered service in 2020.

Technical

The X2 was designed for old main lines with tight curves and with continuously welded rails (the train has a maximum axle load of 17 tonnes (16.7 long tons; 18.7 short tons), which causes large forces on the track). However, since 1990 a lot of new high speed lines have been constructed in Sweden, both upgraded lines and new lines. These upgraded or new lines always have ATC, continuously welded rails on concrete sleepers and no crossings with road and rail at the same level. The tilting function is not used on these lines.

The max power continuous output of the power car is 3,260 kW (4,370 hp), which is comparatively low for a fast train. It also enabled SJ to say that it does not consume more power at 200 km/h (125 mph) than older Rc-locomotive hauled trains at 130 km/h (80 mph).

The X2 trains have mostly run at the X 2000 service level, but have periodically been used for Linx traffic (2000–2004) as well as regional services, for which fewer coaches were used to improve acceleration. All X2 trains are maintained at Hagalund depot in Stockholm and Olskroken depot located just before Gothenburg Central Station.

Technical data X2 power car

Technical data X2 passenger coaches

Each train also has a UB2X coach with a driver's place, and a URB2 coach with a simple restaurant.

In the beginning there were many more UA2 first class coaches than UB2 second class coaches. But after a decision that state employees should normally use second class for train journeys in their works instead of first class, something many companies followed, many UA2 have been rebuilt into UB2.
