SJ

Sweden got there before the rest of Europe: network and operations were separated as early as 1988, and long-distance passenger services were fully opened up around 2010. SJ is therefore today a state-owned passenger railway among several providers – and it runs on tracks where trains keep to the left.

Also known as: SJ AB · Statens Järnvägar · Swedish State Railways

Key takeaways

  • SJ only runs passenger services. Freight was spun off as Green Cargo in 2001.
  • Sweden's railways run on the left – unlike its roads, and unlike neighbouring Norway.
  • The market is open. Since around 2010, commercial operators have been free to compete in long-distance services.
  • Litra letters classify the fleet: X for electric multiple units, Y for diesel railcars, T for diesel locomotives, Rc for electric locomotives.
  • Regional brands are not operators. Öresundståg or Pågatåg tell you the service, not the company.

How to recognise SJ

Does the train really belong to SJ?

Tick off everything that applies to the vehicle in front of you.

  • X before the number marks electric multiple units, such as X2 or X55
  • Y stands for diesel railcars, T for diesel locomotives like the T44
  • Rc denotes the classic Swedish electric locomotive family, still working night trains today
  • A train labelled Öresundståg or Pågatåg is a regional brand, not an SJ product
  • Ore trains on the Malmbanan belong to a rail subsidiary of the mining group, not SJ
  • The country code in the data panel is SE
  • Trains keep to the left – that tells you the right platform side before the train even arrives

Strengths and weaknesses

What the company stands for

  • Same electrification system as Germany – technically familiar territory
  • Many operators on the same routes make for variety
  • Well-developed hub stations with clear platform layouts
  • The Malmbanan in the north offers subjects found nowhere else in Europe
  • The litra system can be learned in a few minutes

Where it falls short

  • SJ is far from the operator everywhere – regional brands regularly mislead
  • Outside the conurbations, services are sparse and journeys are long
  • In winter, usable daylight hours in the north are very short
  • No freight in the company – anyone after that has to follow other firms
  • Left-hand running throws off your location planning if you don't allow for it

Updated: August 2026 – The first train you see pull into a Swedish station comes from the wrong side. Here, the railway runs on the left, even though road traffic switched to the right in 1967. That’s more than a curiosity: it’s the first of several details you need to plan around – and SJ, the state-owned passenger railway, is just one of them.

Keep your Swedish sightings straight

Note down brand, operator and vehicle number separately – then nothing gets muddled in this open market.

A country that got there first

Sweden restructured its railway before Brussels demanded it. As early as 1988, infrastructure was separated out from the state operator and handed to its own agency, from which Trafikverket later emerged. 2001 brought the break-up of the rest: SJ AB took over passenger services, while freight became independent as Green Cargo.

The final step came around 2010, when long-distance passenger services were fully opened to commercial operators. Since then, SJ has been a state-owned company among several competitors – with no special privileges, no network, and no freight.

What’s on the train, and what’s behind it

Sweden is a textbook example of how far brand and operator can diverge. Regional transport authorities award their services under their own brands, and the operating company changes with every tender.

What’s on the train What it is Who can be behind it
X2000 SJ’s product brand for high-speed services SJ
Öresundståg regional network brand across the Öresund link changing operators depending on the tender
Pågatåg regional brand in southern Sweden tendered operation, not necessarily SJ
Inlandsbanan its own line with its own company not SJ traffic
Ore trains on the Malmbanan company traffic of a mining group its rail subsidiary, never SJ
SJ Norge subsidiary in Norway SJ – but on the Norwegian network

The second-to-last row is the most surprising: the country’s heaviest trains have nothing to do with the state railway. Why brand, keeper and operating company are fundamentally three different things is explained in the guide Who’s actually running this train?

Reading litra letters saves you the lookup

X stands for electric multiple units, Y for diesel railcars, T for diesel locomotives, Rc for the classic electric locomotive family. That gives you traction type and vehicle class before you've even read the number – a system similar to Norway's litra, just with different letters.

Four details that upend your planning

Technically, Sweden is close to home: 15 kV at 16.7 Hz, standard gauge, overhead line just like back home. The differences lie in the operating model and in the geography.

Left-hand running is the first. It determines which platform a train arrives at and from which direction the sun hits its front. Anyone who plans their spots the German way regularly ends up standing in the wrong place – how to approach this systematically is covered in the article on planning sun position at a photo spot.

The distances are the second. Sweden is longer from north to south than the map suggests; between Malmö and Kiruna lie travel days, not travel hours.

The light is the third. In the north, usable daylight hours in winter are extremely short, while in summer they last almost round the clock. Both require different planning from a German autumn day.

The fourth difference is structural, and only becomes apparent on a second look: in Sweden, almost everywhere, the party commissioning the service is someone other than the train suggests. Regional transport authorities specify the brand, livery and timetable, while the winner of each tender takes over the actual operation. As a result, a vehicle can have been run by three different companies over the years under the same name, without anything changing on the outside. For sighting logs, this is the single most important point: always note the date, or you won’t be able to reconstruct later who was actually running it at the time.

Translate the platform side for left-hand running

Work out before the train arrives which direction it's coming from. The side is the mirror image of what you're used to from Germany.

Note the brand, but don't read too much into it

Öresundståg, Pågatåg, X2000 – write down what's on the train, and don't infer an operator from it.

Record the litra letter and type number

X, Y, T or Rc plus the number give you traction type and class in one step.

Add the data panel

Country code SE and the full vehicle number make the sighting unambiguous – the structure is explained in the guide to the UIC number.

Estimate the SJ share of your trip

Tick off which types of service occur on your route. The calculator averages these into a rough estimate.

Freight counts as zero in this calculation – SJ fundamentally doesn't run there.

Three railway worlds in one country

Stockholm Centralstation is the place for long-distance and suburban traffic: busy, easy to follow, and with several operators on neighbouring tracks. In the south, Hyllie on the Öresund link shows cross-border regional traffic to Denmark – there you’ll also encounter Danish rolling stock.

Right up in the north lies Abisko on the Malmbanan. The ore railway towards Narvik is operationally the opposite of the rest of the country: heavy, densely scheduled, running around the clock – and without SJ. If you’re heading there in winter, read the article on winter railway photography first.

SJ, transport authority, or competitor?

It's SJ if …

  • the train runs under one of SJ's own product brands
  • the data panel shows an SJ keeper
  • it's a night train in SJ service

Look more closely if …

  • the train carries a regional network brand
  • a vehicle runs in cross-border traffic
  • the livery doesn't match the markings

It's not SJ if …

  • it's a freight train or an ore train
  • a commercial competitor is running long-distance services
  • the train is on the Inlandsbanan

Arctic locations are no walk in the park

Abisko and the Malmbanan lie north of the Arctic Circle. In winter, conditions there quickly push batteries, lenses and people to their limits. Plan clothing, power supply and your way back generously, stay on publicly accessible ground, and never step onto the track – the ore trains arrive faster than their weight would suggest.

Conclusion

SJ is a good example of what a state railway looks like once the restructuring is complete: a passenger operator with no network, no freight, and no monopoly. That doesn’t make identification harder, just different – the starting question isn’t the company, but the vehicle.

If you note the litra letter, type number and data panel, and keep the brand separate from all that, you’ll quickly build reliable sightings in Sweden. And if you plan for left-hand running from the start, you’ll save yourself a few missed arrivals.

In short

SJ is a passenger railway in an open market. The brand on the train tells you less here than almost anywhere else – the litra and the number tell you everything.

Keep brand and operator filed separately

In Sweden's open market, the operator changes faster than the vehicle. Note down both.

Summary

  • Sweden carried out Europe's railway restructuring earlier than most – the results are still visible on the platform today.
  • SJ is one of several passenger railways, not a monopoly. The brand on the train tells you nothing on its own.
  • The litra letters give you the traction type and class, the data panel gives you the keeper.
  • Anyone who combines Stockholm, the Öresund and the Malmbanan sees three completely different railway worlds in one country.

Frequently asked questions

Is SJ the Swedish state railway?

SJ AB is the state-owned passenger operator, not the state railway in the old sense. The former integrated operator Statens Järnvägar was broken up in 2001; freight became Green Cargo, while infrastructure had already been with its own agency for a long time. SJ is today one provider among several.

Do trains in Sweden really run on the left?

Yes. Road traffic switched to driving on the right in 1967, but the railway kept left-hand running. For you on the platform, that's a real planning factor: it decides which side a train arrives on and which direction you'll have the front lit from. Neighbouring Norway drives on the right – if you combine both on one trip, you need to rethink your approach.

What do X2, X55 and T44 mean?

Sweden uses litra letters before the type number. X stands for electric multiple units, Y for diesel railcars, T for diesel locomotives and Rc for the classic electric locomotive family. X2 is therefore an electric tilting train, T44 a diesel locomotive. The system works similarly to the Norwegian litra, just with different letters.

Who owns the tracks in Sweden?

Trafikverket, a state agency that is also responsible for the roads. It was formed in 2010 from the merger with its predecessor Banverket, which had managed the rail infrastructure since 1988. Sweden was thus one of the first countries in Europe to separate network and operations.

What is the Öresundståg and who operates it?

Öresundståg is a regional network brand for services across the Öresund link to Denmark and in southern Sweden. It's not a company: the operating contract is tendered and has changed hands several times over the years. On the Danish side, services from DSB add to the mix. Anyone logging such trains should note the brand and the actual operator separately.

Does SJ also run freight trains?

No. Freight was spun off in 2001 as Green Cargo and has been a separate state-owned company ever since. Private freight operators run alongside it. A freight train in Sweden is therefore never an SJ train – one of the few unambiguous rules this country offers you.

Who runs the ore trains on the Malmbanan?

Not SJ. The heavy ore trains between the mines in the north and the Norwegian port of Narvik are run by a rail subsidiary of the mining group. They're among the heaviest trains in Europe, and they run around the clock. For spotters, Abisko on the Malmbanan is therefore a destination in its own right – with all the difficulties the Arctic climate brings.

Why does a Swedish state railway operate in Norway?

Because Norway tenders out its transport contracts and SJ Norge has won some of them. That puts SJ in direct competition in the neighbouring country with Vy, the state railway there. For spotters, that means vehicles with an SJ connection turn up on Norwegian routes – such as the BM92 and BM93 of SJ Nord.

What electrification system does Sweden use?

15 kV at 16.7 Hz, the same as Germany, Austria, Switzerland and Norway. Technically, Sweden is therefore familiar territory for German spotters. The break lies elsewhere: in the direction of travel, in the distances, and in the winter light situation.

What is the Inlandsbanan?

The Inlandsbanan is a long line through Sweden's interior, operated as its own product with its own company. It's not SJ traffic and follows a completely different timetable pattern – seasonal, tourism-oriented and with its own rolling stock. If you want to see it, plan it as a separate leg of your trip.
