Stadler FLIRT (, ) is a passenger multiple unit trainset made by Stadler Rail of Switzerland. The baseline design of FLIRT is an electric multiple unit articulated trainset that can come in units of two to twelve cars with two to six motorized axles. The maximum speed is . Standard floor height is , but high floors are also available for platform heights of .

The FLIRT train was originally developed for the Swiss Federal Railways and was first delivered in 2004. The trains quickly became a success and were ordered by operators in Algeria, Azerbaijan, Belarus, Canada, the Czech Republic, Estonia, Finland, Germany, Hungary, Italy, Lithuania, the Netherlands, Norway, Poland, Serbia, Slovenia, Sweden, Switzerland, the United Kingdom, and the United States. As of October 2021, more than 2500 units have been sold.

Aside from being electric (EMU), the FLIRT is available in diesel-electric ( DEMU), battery-electric, bi-mode EDMU, tri-mode diesel/overhead electric/battery (see also: Stadler WINK), and more recently hydrogen fuel cell versions. Bi-mode models were first ordered by Italy's Aosta Valley region as ( BTR.813), then by Greater Anglia as the British Rail Class 755, and Norske Tog. Tri-mode versions were first ordered by Transport for Wales (KeolisAmey). Hydrogen fuel-cell versions were first ordered by Arrow in San Bernardino County, California, USA.

Specifications

The FLIRT is a new generation of multiple units, even though the first versions resemble GTW vehicles. The trains can have two to six sections and electric variants are available for all commonly used power supply systems (AC and DC) as well as standard and broad gauge. It has Jacobs bogies shared between the individual coaches, with wide walk-through gangways. The floor height at the entrances can be chosen by the operator, providing level boarding at most stations. Automatic couplers of either Schwab type (on all Swiss units) or Scharfenberg type at both ends of the train allow up to four trains to be connected.

All FLIRT variations use IGBT-based traction converters from ABB, which drive the TSA induction motors located in the two bogies at either end of the train. On the two-section trains, only one bogie is powered, while on longer versions it is possible to have a third powered bogie in the middle, found on the trains for Vy in Norway and for PKP Intercity in Poland. Each bogie usually has a continuous power rating of giving a typical four-section train total power output as well as maximum power output of over a short time. Depending on the number of powered bogies, the length and weight, they will reach top speeds between (typically ). Acceleration also varies between .

The diesel, bi-mode electro-diesel, hybrid diesel-battery, battery, and hydrogen fuel cell versions are essentially baseline design with an additional non-passenger car inserted in the trainset – called a ''PowerPack'' car – which contains the electricity-generating and storage components, such as diesel engines and batteries, that provide electricity to the train to run ''off-wire''. It has a gangway through the centre to allow passengers to pass between the two parts of the train.

In the TEXRail application, the diesel power module contains two Deutz AG TCD 16.0 V8 engines that comply with the US EPA Tier 4 emission standard.

On March 22, 2024 Stadler's FLIRT H2 hydrogen multiple unit secured
Guinness World Record
for the longest distance achieved by a hydrogen fuel cell multiple unit without refueling.

Operators

Algeria

On 18 March 2006, the Algerian operator SNTF announced that it had ordered 64 four-car EMUs for suburban services in Algiers. The trains were delivered between 2008 and 2010.

Azerbaijan

In November 2019, it was announced that Azərbaycan Dəmir Yolları (Azerbaijan Railways) had placed a €115 million order for ten Russian-gauge Stadler FLIRT units in various configurations, for delivery to begin in 2022.

The order specification is as follows:
* Three EMUs for suburban trains
* Three EMUs for regional trains
* Four DŞ1-class DMUs for regional trains
Train length is to range between , with capacity varying from 236 to 271 passengers.

Because the Azerbaijan Railway is currently converting the electrification voltage of many lines on its network from 3 kV DC to 25 kV AC, the diesel fleet will be introduced first, allowing the service to be upheld during this conversion process.

In December 2023, the first DMU DŞ1-001 has been delivered to Azerbaijan Railways.

Belarus

Ten Russian-gauge units were delivered to the Belarusian Railways in 2011. Six more were delivered from 2013 to 2014.

The trains are mostly used on various suburban routes around Minsk, such as Minsk-Pasažyrski to Minsk National Airport. The Stadler FLIRT trains are also used as inter-regional transport in Belarus, on the routes Minsk–Homieĺ, and Minsk– Brest.

Two Stadler FLIRT units with an interior optimised for longer distance (EP^m-class) were delivered to Belarus in 2015 to 2016, and in January 2019, ten more of these trains were ordered for delivery in 2020.

Canada

The city of Ottawa put 7 Stadler FLIRTs into service on O-Train Line 2 in 2025 to increase capacity, replacing the Coradia LINTs, which have been moved to line 4.

Line 2 is a combination of frequent rapid transit and suburban regional rail, serving both as the inner city's main north-south route and also railway to the Riverside South suburb.

Czech Republic

The Czech private operator LEO Express ordered five units. Units are modified as InterCity trains. All five units have operated on the Prague–Ostrava line since December 2012. Since December 2013 one unit is operated on the Prague– Staré Město u Uherského Hradiště and since December 2014 one unit is operated on the international route Prague–Košice (Slovak Republic). The maximum speed of these units is , but in service it is limited to .

Denmark

On 9 October 2024, the local railway operator Lokaltog formally signed a contract for the supply of 14 two-car units of the battery–electric Akku model with an option for 10 more. They are scheduled to be delivered in 2028.

Estonia

Elron ordered 18 electric (6 four-car and 12 three-car) and 20 diesel (6 four-car, 8 three-car and 6 two-car) broad-gauged trains. By June 2014 all 38 trains were delivered. This has been the first time FLIRT DMUs were produced. First five trains went into service on 1 July 2013 and by January 2014 all old trains were replaced by the new ones. On 16 April 2014 one of the new DMUs that had been operating for just five months had an accident near Raasiku, a collision with a truck. The unit was badly damaged. It went back into service in 2015, and two damaged carriages were replaced.
In November 2014, Elron initiated an investigation into suspected flaws in some diesel trains. Two different build flaws were found in many of the trains and faulty components were replaced under warranty.

Finland

81 four-section broad-gauged FLIRT units, classified as Sm5 in the Finnish system, have been ordered by Pääkaupunkiseudun Junakalusto Oy (a joint venture between the cities of Helsinki, Espoo, Vantaa and Kauniainen) for service on the Helsinki commuter rail network. The Sm5 units are leased by Pääkaupunkiseudun junakalusto to the Helsinki Regional Transport Authority, but they are currently operated by the VR Group. The initial order in 2006 was for 32 trainsets. 9 further units were ordered in 2011 and 34 further units in 2014.

The first Sm5 unit arrived in Finland on 11 November 2008. Following preliminary testing the first unit was displayed to the public in Helsinki on 17 December 2008. During the remainder of on 2008 and for most of 2009 the Sm5 units were extensively tested in different parts of Finland. The first unit entered passenger service on 18 November 2009.

In November 2022, VR Group, the country's national rail operator, awarded Stadler Rail the contract to manufacture 20 new FLIRT 4 EMUs (but based on FLIRT G and without Jacobs bogies) with an additional option for 50 trainsets, classified as Sm7, for longer-distance VR commuter rail services. These trains will be partly manufactured in Switzerland with final assembly taking place in Poland and Belarus, and they are expected to enter service in spring 2026.

Germany

The Cantus Verkehrsgesellschaft, a joint subsidiary of Hessische Landesbahn and Hamburger Hochbahn, became the first German FLIRT operator when they received their first train in 2006. Their fleet consists of fourteen three-car and six four-car units.

Since December 2007 Abellio Rail NRW has operated nine three-car and eight two-car FLIRT trains for regional routes between Essen, Hagen, Iserlohn and Siegen. This was the first time that a FLIRT with only two sections was ordered.

Also since December 2007 WestfalenBahn uses fourteen three-car and five five-car trains for trains services in the Teutoburg Forest region.

In 2006 DB Regio, a subsidiary of Deutsche Bahn ordered five five-section vehicles for regional services on the German east coast. The trains were delivered in August 2007 and, until December 2019, were used on the routes Rostock–Stralsund–Lietzow–Sassnitz (Hanse-Express), Sassnitz–Stralsund and Binz–Lietzow. Since October 2020, they run the RB17 (Wismar – Ludwigslust).

The biggest order from Germany so far came in October 2006 from the leasing company Angel Trains Europa when they ordered 25 four-car FLIRT trains. All 25 units have been leased to Eurobahn who uses them on the Hellweg Network in North Rhine-Westphalia. Only a year later, in November 2007, Angel Trains ordered four more four-car and fourteen five-car trains that will also be used by Eurobahn. In 2017, Eurobahn also took over the WestfalenBahn operation of the Teutoburger-Wald-Network, taking over 18 FLIRT 1 units, as well as ordering eight new FLIRT 3 units.

On the InnoTrans 2008, a trade fair focused on rail transport, Vias announced their order for twelve four-section and seven three-section units. Starting in December 2010, the trains were put on the Frankfurt–Koblenz route. The same year, the Hessische Landesbahn (HLB) started to operate three three- and five six-car FLIRT units on the Frankfurt – Gießen – Siegen line.

Starting in December 2013, the Bayerische Oberlandbahn, called Bayerische Regiobahn (BRB) since 2020, uses three three-car and 28 six-car FLIRTs for their Meridian services, which run between Munich-Salzburg and Kufstein. Since August 2014, the ownership of the trains was transferred to AlphaTrains, only to be leased back for the Meridian.

From December 2014 on, the RE 1 (Koblenz – Trier (– Luxembourg /) – Saarbrücken – Ludwigshafen – Mannheim), RE 2 (Koblenz – Frankfurt), RE 4 (Frankfurt (Main) – Mainz – Ludwigshafen – Karlsruhe), RE 14 (Frankfurt (Main) – Mainz – Ludwigshafen – Mannheim), are operated with FLIRT 3 units, with the RE 1 being coupled with a CFL-operated KISS between Trier and Koblenz.

Go-Ahead Germany ordered 45 units in 2016 for delivery in 2019.

Transdev ordered 64 three-car units in November 2018, planned to enter service in 2021 on Hanover S-Bahn lines. In June 2019, Transdev subsidiary NordWestBahn awarded Stadler a €100m order to supply 16 FLIRT electric multiple-units for the Bremen/Niedersachsen S-Bahn services. The trains will enter service starting December 2022.

In July 2019, Schleswig-Holstein rail authority NAH.SH awarded Stadler a €600m order for 55 battery-powered FLIRT Akku multiple unit trains along with maintenance for 30 years. The trains, which offer of battery range, were originally scheduled to enter operations in 2022 to replace DMUs on non-electrified routes. Regular operations began in October 2023.

Lithuania

On 21 June 2023, Lithuanian passenger rail operator LTG Link announced that it has ordered nine 5-car Stadler FLIRT EMUs and six 3-car FLIRT battery-electric multiple units, along with an option for a further 13 electric and 26 battery-electric units. The trainsets are expected to began testing in 2025 with a projected entry to service in 2026.

Netherlands

On 23 April 2015 the Netherlands' railway operator Nederlandse Spoorwegen announced that it was ordering 58 Stadler FLIRT EMUs, comprising 25 four-car units and 33 three-car units, to be delivered by the end of 2016. The very short delivery deadline (20 months), to meet capacity needs, allowed NS to invoke 'urgency mode' provisions in EU procurement rules and place the order without tendering. The 58 FLIRT EMUs for NS were produced at Stadler's plant in Siedlce, Poland, 92 km east of Warsaw, following the order which that plant completed for PKP Intercity in Poland. Meanwhile, Arriva Nederland also ordered two- and three-car units for operation in the province of Limburg.

, FLIRT 2, 3 and 4 EMUs are in service in the Netherlands with the following operators:
*Arriva
*Connexxion
*Nederlandse Spoorwegen (some of them with R-net branding)
*Keolis (Blauwnet and RRReis branding)

Norway

50 Flirt units were ordered by Vy (formerly Norwegian State Railways (NSB)), with a further 100 on option. 26 units were placed on Oslo Commuter Rail and the remaining 24 units were used on regional and express routes. During spring and summer 2012 all Flirt trains used by Vy were fitted with free wireless Internet access for passengers. In Vy's system, the FLIRT trains are classified as ''Class 74'' for regional trainsets and ''Class 75'' for local trainsets.

All trains will be five-car sets; unlike previous five-car FLIRTs each will have a third powered bogie giving it a maximum power output of and a top speed of . Trial runs started on the Bergen Line in 2009, using an SBB-CFF-FFS unit. The first units were scheduled to enter passenger service on 29 February 2012. The FLIRT's introduction was delayed after a unit derailed during tests by NSB on 15 February 2012, injuring five people. The train was running much too fast, and there were no safety systems along the railway to catch the driver's error.

The first train entered regular service on 2 May 2012 on the line from Skien to Lillehammer. The last of the 50 trains was delivered on 24 January 2014. Vy had ordered a further 57 trains, for a total of 107, as of October 2015. In 2017 an order for additional 18 was placed, for a total of 125, forty of which are short regional trains, and the rest local commuter trains. In July 2018, 36 short regional and 64 local commuter trains had been delivered.

Local Class 75 trains are configured with five seats (2+3) abreast. The Class 74 regional trains were also delivered with 2+3 seating on regional trains except in the premium "Komfort" section that had 2+2 seating. Significant passenger complaints over cramped seating led Vy to reconfigure the regional trains into 2+2 seating in 2014.

These fleets have floor without steps. Many Norwegian platforms are too low for this floor height, so they will have to be raised to platform height. These fleets cannot operate on low-platform lines such as the Bergen Line, the Sørlandet Line west of Kongsberg, and the Dovre Line north of Lillehammer. Raised platforms will be matched with conventional train steps; vertical gaps between this fleet and platforms will remain.

In 2018 the last options were used, which includes 25 trainsets, most of which include the Class 75 and 74 that are set to operate on Gjøvikbanen and Vossebanen.

The two last are bi-mode trains named ''Class 76''. These are similar to the FLIRT 3s owned by Greater Anglia in the UK but each will have an extra carriage for diesel generators in order to operate on tracks without electrification and as fully electric on electrified parts of the railway.

In total 14 trainsets of the bi-modal Class 76 will be delivered to serve Trønder Commuter Rail as well as the Meråker and Røros Lines. These will replace the aging Class 92's built by Duewag which are fully diesel. All this is included in Bane Nor (Norway's Rail Management Agency) and Jernbaneverkets's plan to finally modernize the Trøndelag Railways, which have outdated buildings and infrastructure. These lines were partially electrified, between Støren and Trondheim, by 2021, with further electrification to be implemented.

In November 2022 the final 150th train set was delivered.

In February 2023 Norway ordered 17 FLIRT NEX long-distance trains, with the option of up to 100 train sets, to enter testing in 2025 and service on the Bergen Line in 2026, replacing end-of-life trainsets on the line. These will be classified as 'Class 79' and have 8 wagons including reclining seats, flexible sleeping compartments that can be used as private seating areas during daytime use, bistro, and a family area.

United States

On 9 June 2015 Trinity Metro signed a contract for the supply of eight four-car articulated FLIRT3 diesel-electric multiple units for the TEXRail commuter line, which opened in January 2019. The contract was signed at a ceremony held at Fort Worth Central Station. The contract is valued at $107 million, and includes the supply of components for 10 years. The contract also includes an option for an additional 24 DMUs. This is Stadler's first order for its FLIRT family in the US (previous orders have been for the GTW), and the first to include federal funding and thus be subject to the Buy America Act. As such, one element of the contract is that the final assembly of the trains will take place in the US, and several assembly sites such as in Lewisville were considered for the facility. Stadler eventually leased space from the Utah Transit Authority in their former Union Pacific shops in Salt Lake City, Utah.

Public unveiling events for the completed American-built FLIRT units occurred in both Atlanta, Georgia on 9 October 2017 and Salt Lake City, on the Salt Lake, Garfield and Western Railway, on 13 October 2017 as Stadler broke ground for their permanent Salt Lake facility.

Three two-car FLIRT sets were built for the Arrow commuter rail service in Redlands, California, which started operation in 2022. The $31.4 million contract includes the vehicles themselves, spare parts, and training for servicing and operation. In November 2019, the San Bernardino County Transportation Authority ordered an additional FLIRT powered via hydrogen fuel cell, the first such train in the United States. In September 2022, an order of four additional hydrogen-powered trains was announced by Stadler and CalSTA for Amtrak California inter-city services.

Eight four-car sets are to enter service with Dallas Area Rapid Transit on the Silver Line when it opens in 2026.

In February 2024, Metra ordered 16 of the battery–electric Akku model, expected to be delivered in late 2027, for use on the Beverly Branch of the Rock Island Line or North Central Service.
