Current

X2 (X 2000)

The X2 trains (operated by SJ as X 2000) launched in 1990, and are used for higher-speed services and have a top speed of 200 km/h (125 mph). Built in Sweden by Kalmar Verkstad, later ADtranz, they feature tilting technology to reduce the effects of high-speed turns. These trains serve several routes, including Stockholm–Gothenburg (Västra Stambanan) and Stockholm–Malmö (Södra Stambanan). They have also previously served the Stockholm–Sundsvall, Stockholm–Strömstad, Stockholm–Oslo, and Stockholm–Östersund–(Duved) lines, with seasonal services on some of these routes. Currently, 36 X2 sets are in operation.[10] Since 2021 the X2 fleet has been undergoing refurbishment, due for completion in 2026.[11]

X55 (SJ 3000)

The X55 (operated by SJ as SJ 3000) is an electric multiple unit built by Bombardier introduced in 2012. It has a top speed of 200 km/h and serves various routes, often north of Stockholm, including Stockholm-Östersund-(Duved) (Mittbanan-Norra Stambanan), Stockholm-Uddevalla (Västra Stambanan and Bohusbanan), Stockholm-Gothenburg, Stockholm-Sundsvall-Umeå (Ostkustbanan, Botniabanan), Gothenburg-Malmö (Västkustbanan), Stockholm-Oslo, Stockholm-Karlstad (Västra Stambanan and Värmlandsbanan/Kongsvingerbanen), and Stockholm-Falun/Mora (Dalabanan).[12]

X40

The X40 is a variant of the french Coradia Duplex double-decker electric multiple unit built by Alstom used for regional services, launched in 2006. It typically serves shorter routes such as Stockholm Central–Gävle Central. These trains are typically used for services that do not travel longer than 4 hours, with some exceptions like the Coast to Coast (Gothenburg-Kalmar) and Stockholm-Gothenburg via Västerås. The X40 has no catering service, and is mostly composed of second-class seating, with a small first class section, although the seats do not differ between first and second. The only exception being more legroom on refurbished units. All 27 three-car units are currently undergoing refurbishment by VR FleetCare in Oulu, due to be complete in 2027. With options to refurbish two-car units later.[13]

Rc-hauled Trains

Many InterCity services are often operated using Rc-hauled trains, which are paired with various carriages, such as the SJ B7, or other first class, second class, and sleeper carriages. The Rc-hauled trains often also feature an onboard bistro car.[14]

Future

Alstom Zefiro Express (X250)

25 high-speed Zefiro Express high-speed trains (SJ X250), scheduled to enter service in 2027, will operate on routes including Stockholm–Malmö, Stockholm–Gothenburg, and be certified for cross-border services to Denmark and Norway. The trains, with a top speed of 250 km/h, and are designed to handle running at temperatures of -40 degrees. The contract, valued at SEK 7 billion (EUR 630 million), was awarded to Bombardier (now part of Alstom) by SJ in 2021. The trains are constructed in China and finalised at the Alstom plant in Hennigsdorf, Germany. The first units started testing in 2026 in Germany, and are expected to enter service in December 2027 on the according to Petter Essén, Head of Strategic Planning at SJ.[15][16][17]

CAF Civity Nordic (X45)

25 CAF Civity Nordic (SJ X45), scheduled to enter service in 2027, will operate on regional routes including Stockholm-Västerås-Örebro-Skövde-Gothenburg, Linköping-Norrköping-Stockholm-Arlanda-Uppsala-Gävle-Ljusdal and Kalmar-Gothenburg. The trains are designed for cold weather conditions in Sweden, and can operate with a top speed of 200 km/h. The contract, valued at EUR 300 million, was awarded to CAF by SJ in 2022, the first units were expected to arrive in Sweden for testing in 2025 and enter revenue service in 2026. The project is as of April 2026 running one year behind schedule and will be delivered in autumn 2027.[18][19]

Sleeper services - SJ Nattåg

The SJ overnight train services (Swedish: SJ Nattåg) are Rc locomotive-hauled trains with both sleeper wagons as well as standard wagons. All services except for the Stockholm-Malmö route have a bistro wagon.[21]

As of 2022 SJ has in collaboration with DSB and RDC begun to operate night train services between Sweden and Germany through Denmark. Three different locomotives are used due to compatibility issues with the electrification and signaling systems between the three countries.

Within Sweden SJ Rc locomotives are used, and in Denmark DSB EA locomotives are used, and in Germany DB 101 locomotives are used.[22]

The night-trains operate on the following lines:

SJ InterCity

The InterCity services are Rc-hauled trains with standard-seating carriages in both first and second class. There is always a bistro car available in the trainset.[23]

Lines with InterCity service:

SJ Regional

Most of the SJ Regional network was concentrated in the area around lake Mälaren. Operated with either Rc-hauled trainsets, X12/X14 or X40 EMUs. These trains have no catering on board. The X40 is equipped with free 4G WiFi. Both first and second-class are usually offered.[24] Most of this network has been incorporated into the new Mälartåg franchise, although some services remain outside of it.

In Feb 2026, Västtrafik, Hallandstrafiken and Jönköpings Länstrafik awarded SJ an 11-year contract to continue operating the Västtågen regional train system from 12 December 2027.[25]

Routes listed below are the satellite routes which are not subject to franchising.

Franchised operations

SJ operate a couple of regional rail franchises held by public transport authorities around the country. The most significant of these are Mälartåg and Västtågen serving the Mälaren valley and the region of West Götaland respectively. SJ AB also started operating the Öresundståg franchise for the 2020 timetable, taking over from Transdev. But due to serious inconsistencies between partners the contract will be terminated as of December 2022 where Transdev will take over again.

MTR took over the Mälartåg contract in December 2021.

The stretch Malmö Central to Copenhagen Central is operated 50/50 alongside Danish State Railways (DSB) and Copenhagen to Østerport/Nivå by DSB only.

The initial contract for the Mälartåg franchise states that the operator may use their own fleet [of X12, X40 and X50 stock] until the delivery of ER1 Stadler Dosto 200 EMUs is completed. The Upptåget franchise will be merged into Mälartåg onwards from the 2022 timetable, meaning that services from Gävle gain additional stations inherited from the termination of the Upptåget franchise.

SJ higher speed trains

SJ higher speed trains (Swedish: SJ Snabbtåg) are X2 or X55 trains operating on the main routes in Sweden. The trains are equipped with WiFi and have a bistro.[26] Stops at Arlanda and Uppsala are for boarding northbound or alighting southbound respectively, although passengers with railcards are exempted from this rule. Some services do also allow both boarding and alighting at Arlanda and Uppsala respectively.
