Stadler FLIRT (Fast Light Innovative Regional Train) is an electric multiple unit (EMU) produced by Stadler Rail AG. The articulated trainset comes in units of two to six cars with two to six motorized axles. The maximum speed is 200 km/h (120 mph). Standard floor height is 57 cm (22.4 in), but 78 cm (30.7 in) high floors are also available for platform heights of 76 cm (29.9 in).
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, Belarus, Estonia, Germany, Finland, Hungary, Italy, Norway, Poland, and Switzerland. In November 2009, the order book stands at 547 sold units.
The FLIRT is a completely new developed light regional railcar even though it has a striking resemblance with GTW vehicles. The trains can be ordered with two to six sections and are available for all commonly used power system (AC and DC) as well as standard and broad gauge. Due to the use of jacobs bogies between the sections the whole trains becomes one single cabin that can be walked through. 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 and disconnected quickly.
All FLIRT variations use IGBT power converters to drive the 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 (currently only the trains for NSB). Each bogie usually has a continuous power rating of 1,000 kW (1,300 hp) giving a typical four-section train 2,000 kW (2,700 hp) total power output as well as maximum power output of 2,600 kW (3,500 hp) over a short time. Depending on the number of powered bogies, the length and weight, they will reach top speeds between 120 and 200 km/h (75 and 120 mph) (typically 160 km/h or 99 mph). Acceleration also varies between 0.8 and 1.2 m/s2 (2.6 and 3.9 ft/s2).
The Swiss Federal Railways were Stadler's first customer for the FLIRT when they ordered 42 units with options for 100 more in September 2002. The first vehicle was delivered in 2004 for the use on the Stadtbahn Zug.
Meanwhile the Swiss Federal Railways have ordered a total of 117 units that can be broken down into four different types that differ in their equipment for driving in neighboring countries. The base version is the RABe 523 that is used on the Stadtbahn Zug and the RER Lausanne. These 43 four-section units can only be used within Switzerland. The 30 RABe 521 and 14 RABe 522 are versions that can also be used in Germany and France respectively. They also consist of four sections and are used on the Basel S-Bahn. The last version is the Italy-capable RABe 524/ETR 150 that is used on Treni Regionali Ticino Lombardia (TILO) services in Ticino and northern Italy. The first 19 units of this type to be delivered were four-sections long, and were followed by eleven units ordered that six-sections long and are additionally equipped with the ETCS Level 2 train control system.
Besides the Swiss Federal Railways two other companies in Switzerland operate FLIRT trains: The Südostbahn uses 11 trains with the designation RABe 526 and the Transports Régionaux Neuchâtelois owns three trains (RABe 527).
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 14 three-car and 6 four-car units.
Since December 2007 Abellio Rail NRW operates 9 three-car and 8 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 Westfahlenbahn GmbH uses 14 three-car and 5 five-car trains for trains services in the Teutoburg Forest region.
In 2006 DB Regio, a subsidiary of Deutsche Bahn AG ordered five five-section vehicles for regional services on the German east coast. The trains were delivered in August 2007 and are now used on the routes Rostock-Stralsund–Lietzow–Sassnitz (Hanse-Express), Sassnitz–Stralsund and Binz–Lietzow.
The biggest order from Germany so far came in October 2006 from the leasing company Angel Trains Europa GmbH 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 4 more four-car and 14 five-car trains that will also be used by Eurobahn.
On the InnoTrans 2008, a trade fair focused on rail transport, VIAS GmbH announced their order for 12 four-section and 7 three-section units. Starting in December 2010, the trains will be put on the Frankfurt–Koblenz route.
41 four-section 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 & Kauniainen and the VR Group) for service on the Helsinki commuter rail network. The Sm5 units will be leased by Pääkaupunkiseudun junakalusto to the Helsinki Metropolitan Area Council, but they will be operated by the VR Group. The initial order in 2006 was for 32 trainsets. Nine further units were ordered in 2011.
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 Italy FLIRT are used by six regional railways, in total units ordered and built are so divided among the following companies:
Ferrovie del Gargano: name ETR 330, single voltage to 3 kV DC, maximum speed 160 km / h. Fleet: three units.
SAD used on Val Pusteria Railway name ETR 155 and ETR 170. C.a dual voltage 15 kV / 3 kV cc. Fleet: four units (ETR 155) and four units (ETR 170), In July 2011 have been ordered eight new units for routes within the jurisdiction of SAD.
Sistemi Territoriali: name ETR 340, single voltage to 3 kV DC, maximum speed 160 km / h . Fleet: two units from 2008, four and sixteen FLIRT ordered in 2009. The FLIRT ordered in 2009 will be built in conjunction with the AnsaldoBreda: the Stadler Rail will carry vehicles head of convoys, systems of traction and onboard auxiliary, the bogies and bearing while AnsaldoBreda realize intermediate cars, the staging and the final composition of the train and the delivery to the operators at the plant in Pistoia.
Tilo (Switzerland / Italy):  RABe 524/ETR 150 C.a dual voltage 15 kV / 3 kV cc. Maximum speed 160 km / h. The first 19 units of this type to be delivered were four-sections long, and were followed by eleven units ordered that six-sections long and are additionally equipped with the ETCS Level 2 train control system.
Ferrovie Emilia Romagna: twelve units, in conjunction with the construction AnsaldoBreda: the Stadler Rail will carry out the head of the convoys of vehicles, systems, traction and onboard auxiliary, engines and carriages bearing while AnsaldoBreda carry out intermediate cars, the staging and the final composition of the train and the delivery to the operators at the plant in Pistoia.
50 Flirt units were ordered by the Norwegian State Railways (NSB), with a further 100 on option. Twenty-six units will be used on the Oslo Commuter Rail and the remaining 24 units will be used on regional and express routes. During spring and summer 2012 all Flirt trains used by NSB are to be fitted with free wireless Internet access for the passengers. In the NSB system, the FLIRT trains are classified as "class 74" for regional trainsets and "class 75" for local trainsets.
All trains will have five cars. However, in contrast to previous five-car FLIRTs they will have a third powered bogie giving them a maximum power output of 4,500 kW (6,000 hp) and a top speed of 200 km/h (120 mph). Trial runs started on the Bergen Line in 2009, using a SBB-CFF-FFS unit. The first units were scheduled to enter passenger service on 29 February 2012. The FLIRT's introduction was put on hold after a unit derailed during tests by NSB on 15 February 2012, injuring five people. The train had been entering a bend at 135 km/h (84 mph) instead of the allowed maximum speed of 70 km/h (43 mph). The first train entered into regular service on 2 May 2012 on the line from Skien to Lillehammer.
The NSB trains have a high seat density, with five seats (2+3) abreast, except for the "Komfort" section of the regional trains that have 2+2 seating. Some passengers have complained that the seats are too cramped, while NSB argue that more seats reduces the number of passengers who are forced to stand during peak traffic.
The Czech private operator LEO Express ordered 5 units.  Units are modified as InterCity trains. All 5 units have operated on the Prague–Ostrava line since December 2012. The maximum speed of these units is 189 km/h (117 mph), but in service it is limited to 160 km/h (99 mph).
