Track maintenance in Stockholm

From June 25 until August 19 2018, inclusive, trains between Stockholm and the south of Sweden will stop at Flemingsberg station and Stockholm Södra instead of Stockholm Central.

What does this mean for passengers travelling by train this summer?

The track maintenance work means that all SJ trains from the south to Stockholm Central or south-bound from Stockholm Central will travel to and from Stockholm Södra or Flemingsberg station instead.*

The easiest way to get to and from Stockholm Södra and Flemingsberg is to travel by SL commuter train. The commuter trains depart from and stop at Stockholm City, a commuter train station adjacent to Stockholm Central.

We have gathered information that can be helpful for you who will be travelling to, from and through Stockholm this summer:

Purchasing a ticket: Here you will find information regarding SJ and SL tickets.

Before the trip: Here you will find information regarding how early you need to arrive at the station, what the difference is between Stockholm Central and Stockholm City and what refreshments we offer onboard the trains. 

During the trip: Here you will find information regarding how much time you need to change between your SJ train and the commuter train and how to find the commuter trains.

 

*Some trains will go another way, north of lake Mälaren, and can therefore depart from Stockholm Central as usual. The station information in the timetable and on your ticket is always correct. Read more.

What is the Wasp Waist?

Over three summers, the so-called Wasp Waist in central Stockholm will be closed for intensive renovation work. But what is the Wasp Waist? And why is it so critical for Sweden's rail system?

Did you know that all trains to and from the south of Sweden pass along the same bit of track? The so-called Wasp Waist is not much to boast about size-wise − it comprises two tracks stretching two kilometres − but the odds of you having travelled along it are pretty high. The Wasp Waist is Sweden's most trafficked cross section of regional trains, high-speed trains and freight trains. On average, a train travels along this track every third minute!

The Wasp Waist stretches from Stockholm Central to its neighbouring station, Stockholm Södra. It passes across Riddarholmen and Gamla Stan, two of Stockholm's most renowned districts where buildings of cultural interest flank the streets. The Wasp Waist can also claim a long history. The tracks crossing the bridges south of Stockholm Central were inaugurated back in 1871. Traffic then was much lighter than today. Approx. ten trains per day travelled these tracks. In 2014, the number was up to 600.

A new opportunity

Heavy use of the Wasp Waist means two things: firstly, there is more wear and tear on the tracks, and secondly, track maintenance is difficult without causing major disruptions to rail traffic. The Wasp Waist has not been properly overhauled since the 1950s, and parts of it have now reached the end of their technical lifespan. When the new commuter train line, Citybanan, was opened last year, the pressure on the Wasp Waist lifted − and the opportunity to renew this railway route also opened up. Now Sweden's most popular and vulnerable railway intersection is to be made fit for the next hundred years.

What's happening in 2018-2020?

Right now, one of Sweden's most ambitious renovation and modernisation projects within rail traffic is taking place. This is how the country's busiest railway section − the Wasp Waist − is being prepared for the future.

For eight weeks this summer, the rail tracks between Stockholm Central and Stockholm Södra will be closed. The track will also be closed during the summers of 2019 and 2020. Some complementary work may be carried out between the closures. This renovation of the Wasp Waist's double track is a huge investment by the Swedish Transport Administration. So what, exactly, will they be doing?

The areas affected by the Wasp Waist renovation are Tegelbacken, Norrström bridge, Riddarholmen, Söderström bridge, the tunnel under Södermalm and the area around Stockholm Södra. Preparation work has been completed at Älvsjö freight train yard, Karlberg and Fatbursparken.

  • New tracks and new equipment

All tracks, overhead lines, contact lines, switch-tenders and signal systems will be replaced or modernised along the entire Wasp Waist section.

  • Tunnels will be renovated

The tunnels under Södermalm and Riddarholmen will undergo much needed renovation and rejuvenation. In Södertunnel, for example, water and road salt leakages as well as damage to concrete and reinforcements will be rectified.

The work on Riddarholmen is estimated to be finished by the turn of the year 2018/2019. Focus is on renovating and adding a new proofing layer to Riddarholmstunnel. The barriers will be renovated, new support walls will be constructed and noise-protection panels will be erected.

  • Bridges rebuilt

The bridges across Tegelbacken, Norrström, Söderström and Söder Mälarstrand play a vital role in the Wasp Waist renovation project. The pillars and foundations are in excellent condition and, with a few minor repairs, are expected to last for a very long time. The steel structures on the bridges, however, are in bad condition. In 2007, the Swedish Transport Administration stated these structures should be replaced within ten years. As part of the renovation process, these structures will be lifted off via the water, where the pedestrian and cycle decks are. The new structures will then be lifted into place, again via the water.

… How much do you know about the Wasp's Waist?

1. The Wasp Waist is Sweden's most trafficked intersection for regional trains, high-speed trains and freight trains. All passenger trains to and from the south of Sweden pass here. That's an average of one train every three minutes!

2. The name "Wasp Waist" refers to the shape of the tracks; several tracks at each end are reduced to two in the middle.

3. A third track to handle the increase in traffic was in the pipeline for a long time. The plans were abandoned in favour of building the new Citybanan tunnel, but not before the work had begun on the third tack. Today, all that remains of the 'third track' is a souvenir 300+-metre tunnel running to the east of Södermalmstorg and under the Överkikaren district.

4. The section called Wasp Waist today was originally inaugurated in 1871. Little has been renovated since the 1950s. The rails and switch-tenders are regularly plagued with cracks and the need to renovate is huge.

5. The opening of Citybanan finally gave the Wasp Waist a colleague who could help handle the train traffic between Södermalm and T-Centralen. The commuter trains now running on Citybanan used to account for 60% of all train traffic along the Wasp's Waist.

6. The Wasp Waist is being renovated by a Swiss company − Implenia. Implenia's contract is worth ca SEK 885 million and includes, among other things, the replacement or repair of major constructions such as bridges and tunnels. Implenia is the leading supplier of construction services in Switzerland. The company has previously been involved in other projects in Sweden, such as Stockholm Bypass.

7. The pedestrian and cycle decks across Norrström and Söderström will be closed at intervals during the renovation project: from spring 2019 until the turn of the year, and between spring and autumn in 2020.

8. The Wasp's Waist renovation is expected to cost SEK 3.2 billion and be completed in 2021. These popular tracks will then be fit to host Sweden's train traffic for many years to come.
