SJ is the primary passenger train operator in Sweden. A wholly state-owned company operated for-profit under market conditions, SJ operates various services across Sweden. SJ's operations include high-speed trains, intercity trains, night trains, and regional trains, with some services extending into Denmark, Norway and Germany.[5][6]
SJ traces its roots back to 1856,[7] however was established in its current form as a passenger train operator (SJ AB) in 2001, following the restructuring of Statens Järnvägar, the former government agency responsible for the Swedish railways.[8] SJ AB also has subsidiaries such as SJ Götalandståg, SJ Stockholmståg, and SJ Krösa, which operate procured regional services in various parts of Sweden. Since 2020 SJ Norge has operated regional services in Norway on behalf Jernbanedirektoratet. In 2025, SJ carried almost 1.5 million passengers in august 2025.[9]
Overview
SJ AB was formed in 2001, following the restructuring of Statens Järnvägar. This restructuring divided the agency into six separate state-owned limited companies, including SJ for passenger trains, Green Cargo for freight, and Jernhusen for railway buildings. SJ's operations fall broadly into subsidised and unsubsidised services. The unsubsidised services ran until the 2011 monopoly. The subsidised trains are awarded through competitive bids. However, some trains fall in between these categories, since public transit agencies can pay SJ to allow transit pass holders access to SJ's trains.
SJ received a government bailout a few years after its creation, but has since had profit margins of up to ten percent. All train operators in Sweden pay low track access charges to the track authority, Trafikverket.

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]

Services
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
Ticketing
Ticket prices on SJ trains vary, similarly to airfares, with the lowest prices typically available when booking ahead.[30] SJ offers different ticket categories, such as non-rebookable and refundable tickets, each with varying levels of flexibility. Additionally, there are certain discounts for seniors, students, youths, and families.[31]
In September 2023, SJ removed its ticket machines from stations.[32] The machines were phased out due to a decline in customer usage and the machines' reliance on older technology.[33] SJ directs passengers to purchase tickets via their website, the SJ app, or through authorised agents. It is not possible to buy tickets on board SJ's trains.[34] Additionally, since September 2009, passengers are required to carry an identity document while traveling on SJ trains.[35]
