X60 is a series of Coradia Nordic 6-car articulated electric multiple units operated by Storstockholms Lokaltrafik (SL) on the Stockholm commuter rail network. They were manufactured by the French manufacturer Alstom at their plant in Salzgitter, Germany between 2005 and 2017, and replaced all older X10 units.

Background

[edit]

The original cars for the Stockholm commuter rail service, called X1, were delivered between 1967 and 1975. A batch of new cars, designated X10, were delivered between 1983 and 1993. These two sets of cars made up the backbone of the fleet from 1967 until 2005. As time went on and passengers demanded more comfortable travel and more features, SL came to realize that it was time to replace the older stock completely. The Regina model by Bombardier Transportation was originally considered, but was factored out due to poor acceleration and the lack of entrance doors, leading to the development of the brand-new X60 model.

The driving cab of the X60B is equipped with ERTMS/ETCS, which is to be installed on the X60/X60A

Delivery of the first 71 X60 sets took place from 2005 to 2008, and a further 12 identical units followed in 2012 with the designation X60A. These trains have been replacing the older stock as they are delivered. Service with the X60 was inaugurated on 13 August 2005 at Stockholm Central Station.

Since 2016, 46 new sets, designated as X60B, are being added to the fleet. They are similar to the X60 and X60A but have several new components, including support for ERTMS/ETCS signalling equipment, which is planned to be installed in the new Citybanan tunnel and the rest of the commuter train network. For this reason, the X60B cannot be connected to the older X60 and X60A until the older trains have received the new onboard computer.

The X60B cars are required because of the need to withdraw the older X10 cars, as the Citybanan stations have platform doors which are adopted to the X60, X60A and X60B, and all trains using the tunnel needed to have their doors on the same distance from each other as the original X60.

Safety and comfort

[edit]

Each train set is 107 metres (351 feet 58 inch) long and consists of six articulated cars. Each car can seat 374 and take 530 standees. Two such units coupled together make up a full-length train. It is easy to go through the entire car to find an empty seat, or to move if one part of the unit is crowded, and the design also provides visibility through the length of the car, which SL's passenger surveys found was important in order to help passengers feel safe. SL has also specified lower backrests in the X60 to improve visibility all the way through the car.

Boarding and alighting from the new train is intended to be much easier than doing so on the older commuter train stock. At each door, and in 92% of each car, the floor is at the same level as the station platforms. This means a significant quality improvement for all passengers but particularly for the mobility-impaired.

X60 interior
The actual technical parameters include 92% of the total floor space of each car having a floor height of 760 mm (30 in) rising to 830 mm (33 in) at the gangways, and a maximum floorheight anywhere in the wagons of 1,080 mm (43 in). The trains can travel at speeds of up to 160 km/h (99 mph) although they are only actually used at speeds of up to 140 km/h (87 mph) in Stockholm - a speed of 80 km/h (50 mph) is reached within 20 seconds. The trains have a width of 3.258 m (10 ft 8+14 in) and a height of 4.280 m (14 ft 12 in) above TOR, and a full length of 107.1 m (351 ft 4+916 in).[1]

The train is built in accord with the new nominal platform height of 800 millimetres (31 in) specified for Stockholm commuter trains, higher than the normal Swedish Railway Administration's standard of 500 millimetres (20 in). Passengers notice a significant improvement in the form of a much lower floor height compared to the earlier stock, making boarding and alighting much easier than before.

In each car there are "flexible areas" that have room for wheelchairs, baby carriages and bicycles.

Another new feature is that the trains are equipped with air conditioning in both the passenger and cab areas. The seats have been designed in collaboration with leading ergonomists and representatives for SL passengers.

All cars have security cameras installed, just like the new Stockholm metro cars; this can contribute to increased security. Naturally, other safety details have also been carefully worked out, such as fire safety, with the use of nonflammable and self-extinguishing materials.

Higher environmental standards

[edit]

High environmental standards have shaped the choice of materials in the new commuter trains. 95% of a car can be recycled when they are ready to be scrapped.

When the trains brake, the 3-phase motors act as generators and return electricity to the system rather than converting power to heat, as on a friction brake system. The current that is produced is conducted back to the overhead lines. If there is another train in the same electrical section, this train will use as much of the generated energy as it can.

The trains are designed and built for Swedish weather conditions; This is done by utilizing the roof space for the traction /air supply and auxiliary power converters, rather than placing them underneath the unit. This means they suffer less from snow and ice accumulation, and it should be possible to operate them without service disruptions both in heavy snow and in hot summers (X1 and X10 had problems with the heavy snowfall and froze, disabling them seriously). The technical systems in the train are "doubled," i.e. redundancy is provided, using microprocessor control systems, which greatly reduces the risk of service disruptions.

X61

[edit]

X61 is the name of the Alstom Coradia Nordic railcar which was ordered by Skånetrafiken, the regional public transport organisation in Scania (Sweden), operate 99 X61 trainsets, of which the first batch of 49 trainsets were delivered 2009–2011. An additional 20 trainsets was ordered in 2011[1] and in 2017 further 30 trainsets was ordered.[2] The X61 is based on the SL X60, but with four cars per set instead of six and a total length of 75 m (246 ft), and are operated both as single trainsets and as longer trains made up of two connected four-car trainsets (and it is also possible to use three connected four-car trainsets to get even longer trains). The interior of the X61 is better suited for the often longer distances covered by regional trains, with toilets (which the SL X60 commuter trains do not have) and more comfortable seats. Östgötatrafiken (the public transport organisation in Östergötland) has bought 5 trains of type X61, delivered in 2010, and has ordered eight more, which was delivered 2015. Västtrafik (the public transport organisation in Västra Götaland) has bought 22 X61 trains.

X62

[edit]
Norrtåg X62 trains

Norrtåg (the train ownership company for the public transport organisations in Västerbotten, Västernorrland and neighbour counties) has bought eleven trains of this type for usage in these counties, e.g. on Botniabanan, delivered in 2012. They are called X62 and contain a bistro because of longer travel times, and have a top speed of 180 km/h (110 mph). They have four passenger doors per side versus six or seven for X61.[2] Otherwise, they are quite the same as X61 trains and it is also possible to make two or three connected four-car trainsets to get longer trains.

These trains have become integral to Stockholm's commuter system, undergoing periodic upgrades for digital signaling and energy efficiency to meet growing urban mobility demands as of 2025.

History and Development

Background

In the early 2000s, Stockholm's commuter rail network, known as Pendeltåg, faced significant challenges due to an aging fleet and increasing passenger demand driven by urban growth. The original rolling stock consisted primarily of 104 two-car X1 electric multiple units built between 1967 and 1975, along with 52 X10 units delivered from 1982 to 1993, many of which were inherited from the state railway SJ when private operator Citypendeln AB took over services for (SL) in January 2000. By this time, the oldest X1 units, dating back to 1967, were over 35 years old and urgently required replacement to maintain reliability, while the overall fleet struggled to accommodate the network's daily ridership of 232,000 passengers amid reports of overcrowding during peak hours. To address these issues, SL announced plans in the early to modernize the commuter rail fleet, aiming to enhance reliability, increase capacity, and improve the overall passenger experience on the expanding network. In 2002, SL placed an initial order for 55 Coradia Lirex X60 electric multiple units from , valued at €6.9 million per set, with options for up to 50 more, marking a key step in this modernization effort. This decision was motivated by the need to replace outdated trains and better serve growing commuter needs, including interim measures like leasing 15 X420 units from DSB (Danish State Railways) in 2003 to alleviate immediate capacity strains. The initial planning phases emphasized designing trains compatible with the infrastructure, specifying 6-car articulated units to maximize passenger throughput while fitting existing platform lengths and track configurations. These requirements ensured the X60 series would integrate seamlessly into the Pendeltåg system, providing a scalable solution for future demand without extensive network alterations.

Procurement and Manufacturing

The of the SL X60 trains originated from a frame agreement signed in 2002 between (SL) and , initiating an order for 55 six-car Coradia Nordic electric multiple units at approximately €6.9 million per unit. In 2006, SL exercised an option under this agreement for 16 additional units valued at €120 million, increasing the total to 71 units. These procurements aimed to replace aging X1 and X10 commuter trains on the network. All 71 initial X60 units were manufactured at Alstom's plant in , with deliveries occurring between 2005 and 2008. In 2012, SL ordered 12 more units designated X60A, identical to the original series, which were also built in and delivered that year. Under the same 2002 frame agreement, SL placed a €440 million order in June 2012 for 46 updated X60B units. Production of the X60B series proceeded at , with the first deliveries starting in January 2016 at a rate of two trains per month, completing without delays by November 2017; as of 2025, the full fleet is in operation. The X60 family utilizes 's Coradia Nordic platform, tailored for Sweden's 1435 mm standard gauge and extreme , enabling reliable performance in temperatures as low as -35°C through enhanced heating, insulation, and snow-resistant undercarriage designs.

Introduction into Service

The first units of the SL X60 commuter trains were delivered in 2005 by , following a procurement signed in 2002 for 71 sets to modernize Stockholm's pendeltåg network. These trains entered official service in August 2005, marking the beginning of their deployment on routes radiating from . Prior to full rollout, the X60 underwent extensive testing phases to verify compatibility with the existing infrastructure, particularly the ATC-2 automatic train control signaling system used across the network. This ensured seamless integration with legacy equipment while maintaining safety standards for high-frequency commuter operations. The testing focused on operational performance, including acceleration, braking, and signaling responsiveness under varied conditions. The introduction proceeded as a phased replacement of older rolling stock, such as the second-hand X420 units, with deliveries continuing through 2008 to achieve complete integration of the initial fleet. Additional 12 X60A variants arrived in 2012 to bolster capacity, while the X60B series—comprising 46 units—began delivery in 2016, with progressive integration into the Citybanan tunnel by 2017 to support doubled service frequencies. Early operations highlighted the trains' reliability in Swedish winters, attributed to the Coradia Nordic design's adaptations for extreme cold, including robust heating and anti-icing features that minimized disruptions during harsh weather.

Fleet Operations

The SL X60 fleet consists of 129 units, including 83 X60 and X60A models along with 46 X60B units, all integrated into service by 2018 and operational as of 2025. These trains form the backbone of the (Pendeltåg) network, serving all lines radiating from central to suburbs and regional destinations. Operated by on behalf of (SL) since March 2024, the contract replaces the previous arrangement with Nordic and extends through 2028 as of August 2025, amid ongoing evaluations for future operators. Maintenance responsibilities for the X60 fleet are managed by at three primary depots: Älvsjö in southern , Bro to the northwest, and to the southwest. Routine servicing follows structured intervals, including daily inspections, weekly minor checks, and periodic overhauls every 200,000 to 400,000 km, focusing on components like bogies, , and electrical systems to sustain fleet reliability. Since their introduction, the trains have achieved high operational availability, with 's maintenance regime contributing to reduced and consistent across the network. In May 2025, signed a five-year digital support agreement with SL to advance digital systems on the X60 fleet. In daily operations, X60 units handle peak-hour demands with headways typically ranging from 10 to 15 minutes on key corridors, supporting over 342,000 daily passengers as of 2022. Their integration with the Citybanan tunnel—opened in July 2017—has been pivotal, enabling up to 16 Pendeltåg trains per hour per direction through the central underground section between Tomteboda and Älvsjö, thereby doubling core network capacity and alleviating surface congestion. This setup allows seamless through-running on cross-city routes, enhancing overall system efficiency without the need for transfers at legacy terminals.

Variants

X61

The X61 is a four-car variant of the Nordic platform, tailored for regional passenger services outside the area. It features a total length of 74 meters, a maximum operating speed of 160 km/h, and a passenger capacity of up to 510, including standing room. Each set includes onboard toilets, providing amenities suited to longer regional routes with fewer stops. Compared to the six-car X60 configuration used for commuter services, the X61's shorter formation enhances flexibility on regional lines with lower passenger volumes and more varied infrastructure, while the addition of toilets addresses the needs of extended travel durations. The X61 shares the modular Coradia Nordic base design with the X60, including its electric and low-floor accessibility features. A total of 99 X61 units were ordered for Skånetrafiken, with an initial batch of 69 delivered starting in 2006 and completing around 2014 to serve the Pågatågen in southern . In February 2015, Skånetrafiken ordered 30 more units at a cost of approximately €130 million, with deliveries beginning in 2016 and the final unit arriving in January 2019. Östgötatrafiken ordered its first five X61 units in March 2008 for €50 million, with delivery and entry into service occurring in 2010 on lines in the region. Additionally, two units originally ordered by Jönköpings länstrafik in 2008 were integrated into the fleet. An additional eight were ordered in September 2012 for €80 million, delivered and operational by early 2015. In November 2017, three more were added to the fleet as an option under the prior contract, entering service in spring 2019 and bringing the total to 18 units. Västtrafik placed an initial order for 11 X61 units in December 2008, valued at around €110 million, with all delivered and in service by the end of 2012 for operations around . In March 2011, it exercised an option for 11 additional units under the same framework agreement, which were delivered between 2013 and 2014, resulting in a fleet of 22. The X61 fleet is operated primarily by Skånetrafiken on the Skåne regional network, Östgötatrafiken on routes in , and Västtrafik in the Väst area, supporting increased ridership on non-metropolitan lines. All units remain in active service as of 2025, with maintenance handled by under long-term contracts.

X62

The X62 variant consists of 4-car articulated electric multiple units, built by as part of the Coradia Nordic family for regional services in northern . Unlike the X61, it achieves a maximum operating speed of 180 km/h, enabling efficient inter-regional travel, and incorporates an onboard car to provide options for passengers on extended journeys. In 2008, secured an order for 12 X62 units from Norrtåg, with deliveries beginning in 2011 and the trains entering in 2012. These units are leased through Transitio and have formed the backbone of Norrtåg's fleet for northern operations since then. Norrtåg deploys the X62 on routes across the region and adjacent areas in Västernorrland, , and counties, supporting longer-distance connections with enhanced passenger amenities like the . The design includes reliability adaptations for extreme northern climates, such as roof-mounted traction and auxiliary systems to minimize snow accumulation and ensure functionality in temperatures as low as -35°C. As of November 2025, the full fleet of 12 units continues in active service with no expansions announced, though operations will transition to VR Sverige under a 10-year contract starting December 14, 2025.
