Alstom Coradia

The Coradia is a family of high-performance rolling stock, manufactured by Alstom Transport and offered in various configurations to suit the varying requirements of operators. It is available in both diesel multiple unit (DMU) and an electric multiple unit (EMU) configurations; a high-density double-decker model, the Coradia Duplex, has also been developed. The Coradia uses Alstom's own Onix IGBT traction system, which is promoted as providing smooth acceleration and energy conservation facilities.. ==Operators==

Europe Bulgaria In April 2025, Bulgaria's Ministry of Transport and Communications placed an order for 35 electric Coradia Stream interregional trains plus 15 years of maintenance services. The trains will be operated by BDŽ. A test trainset began test runs across the country's rail network in December 2025, while deliveries of operational trains are expected to begin in August 2026. Denmark Alstom Coradia LINT diesel unit are used in local trains. In June 2021, Alstom announced that it had won Denmark's biggest-ever railway contract, with a total contract value of . The first firm order, which includes a 30-year full-service maintenance agreement, was placed by the Danish state-owned DSB for 100 Coradia Stream IC5 electric trains, and is valued at ; Delivery was originally planned to start in 2024, but was delayed to 2027, due to delays in final design and supply chain issues. Trains will consist of 5 cars with 300 seats, and are being built at Katowice, Poland, and Saltzgitter, Germany. Finland The VR Class Sm4 is used for regional traffic from Helsinki to Hanko, Lahti, Riihimäki, Tampere and Kouvola. France During October 2009, Alstom received an €800 million ($1.2 billion) order for 100 Coradia Polyvalents from French national railway operator SNCF; a €130 million option for 19 more trains was exercised in January 2010. During March 2010, the company was awarded a follow-on €135 million contract for an additional 23 Coradia Polyvalents from SNCF. Germany The Coradia Continental is in operation with several operators in Germany. It was introduced in 2002, and has been ordered by Hamburger Hochbahn (for agilis), DB Regio, Metronom and Hessische Landesbahn (HLB). In December 2020 S-Bahn Nuremberg switched their lines S1 and the new S5 (previously the Allersberg Express) over to the Coradia Continental. On S5 the trains had to be equipped with ETCS due to using the Nuremberg Ingolstadt high speed line. The Coradia LINT is also operated, known by the local designations of DB class 640 and DB class 648. During May 2013, private operator AKN Eisenbahn ordered 14 Coradia Lints worth approximately €60 million. Italy In September 2012, Alstom received a €67 million order from Ferrovie Nord Milano (FNM) for ten additional Coradia Meridian regional trains. Norway January 2022 Norske tog signed an agreement to buy 30 new Coradia Nordic trains from Alstom, with the option to buy an additional 170 trains. The trains are intended for commuter service in the Oslo area and will have six cars and a top speed of 160 km/h. They will be classified as "Class 77" in the old NSB system and "N05" in the new Norske Tog system. Production of the new trains will start in 2023. The first trains are due in Norway for testing in 2026, and the trains will be delivered and put into operation starting later that year. An additional order for 25 more trains was announced in February 2023. 19 of these will be classified N06 and will be outfitted for regional service with more seats and a top speed of 200 km/h. Poland In September 2025 Polish state-owned intercity train operator PKP Intercity awarded a contract for 42 electric multiple units (with an option to buy 30 further trainsets) to Alstom. The EMUs will be based on the Coradia Max variant and are likely to leverage designs used in the NS Intercity Nieuwe Generatie project in the Netherlands, as they will be serving intercity routes with top speed of 200 km/h. Romania In March 2022, the Romanian Railway Reform Authority or ARF (Authoritatea pentru Reformă Feroviară) for short, signed an order for 20 Coradia Stream trains with 15 years of maintenance, which will be leased to CFR Calatori and Romanian private operators. The order has an option for an additional 17 trains, with an additional 15 years of maintenance, bringing the total to 37 trains with 30 years of maintenance. This option was activated in September 2022 when an additional contract was signed. The Coradia Stream model ordered is 160 meters long, has a passenger capacity of 352, and can only run on Romania's 27kV ~ 50 Hz AC network. These are equipped with PZB90 and ETCS Level 2. Sweden The Coradia Nordic is used for Storstockholms Lokaltrafik (designated X60) for commuter services in and around the Stockholm area. In June 2012, Storstockholms Lokaltrafik placed a €440 million ($548 million) order for 46 Coradia Nordic trains; this reportedly brought the total orders of Nordic trains to 129. and have subsequently also been used on O-Train Line 4 to the airport since 2025. The private Charlevoix Railway, in Québec, temporarily operated hydrogen based iLINTs as a demonstration in the summer of 2023. United States Metra is purchasing 200 bilevel Coradia passenger cars and has an option to purchase 300 more, while Virginia Railway Express—who partnered with Metra on the procurement—is purchasing 21 bilevel Coradia trailer cars with an option for another 44 trailers and 4 cab control cars. Africa Algeria In July 2015, the Société Nationale des Transports Ferroviaires (SNTF), Algeria's national railway operator, placed an order with Alstom for the supply of 17 bi-mode Coradia Polyvalent trainsets for use on mainline and intercity services. Dynamic testing for the trains started in December 2017 at Alstom's test centre in Velim, and the first train was delivered to the SNTF on January 29, 2018. The fleet entered service on the national rail network on March 2, 2018. The trains are designated as the Class ZZe under the SNTF's classification system, with series numbers ZZe-01 to ZZe-17. Senegal Alstom began deliveries of fifteen four-car Coradia Polyvalent trainsets for the Train Express Regional between Dakar and the Blaise Diagne International Airport in Senegal in late 2018. ==Accidents and incidents==

• On 16 January 2008, 334017 was involved in a minor collision whilst entering Glasgow Central station. The unit was working the 08:24 Gourock to Glasgow Central service when it collided with an empty, stationary Class 318. The train was travelling at less than 4 mph (6 km/h) when the collision occurred. Four passengers were slightly injured; however only one required hospital attention, and was transferred to Glasgow Southern General hospital in a taxi. The unit was undamaged. • On 16 January 2010, unit 175103 operating the 08:30 service from Manchester Piccadilly to Milford Haven struck two cars at Moreton-on-Lugg crossing between Hereford and Leominster. The front seat passenger in one of the cars was fatally injured, although there were no casualties on the train. The train did not derail. The signaller had raised the barriers in error when the train was approaching the crossing, and he was arrested on suspicion of manslaughter in July 2010; he was convicted of charges under health and safety legislation following a trial at Birmingham Crown Court in 2013, and was fined £1,750 and ordered to carry out 275 hours of community service. The same service collided with a trailer on the Morfa Main level crossing near Kidwelly on 31 January 2011. No-one was injured, but the unit involved, 175108, received nearly £82,000 worth of damage due to striking the trailer at 75 miles per hour (121 km/h). The farmer in charge of the trailer was sentenced to a 36-week suspended jail sentence and was ordered to carry out 200 hours of community work. • On 19 December 2011, unit 175002 collided with a lorry at the Llanboidy level crossing near Whitland. The train was operating the service from Milford Haven to Manchester Piccadilly and the driver of the lorry was arrested on suspicion of endangering safety. • On 30 January 2015, a small explosion occurred underneath a driving vehicle of unit 458501 near Windsor & Eton Riverside station. The Rail Accident Investigation Branch determined that this was caused by a join between three underfloor power cables not being secured correctly when the unit was rebuilt in 2014. • On 15 October 2015, 334016 was involved in a collision on the approach to Uphall railway station. The unit was working the 16:39 Edinburgh to Milngavie service when it collided with an empty Toyota Hilux pick-up truck which had been stolen and abandoned on the tracks. The train was travelling at approximately 75 mph (121 km/h) when the collision occurred. The unit did not derail, but one passenger suffered minor injuries to their hand from broken glass. • On 12 July 2016, an Alstom Coradia was involved in a head-on collision at Andria, Apulia, Italy. At least 20 people were killed. • In February 2018, following the discovery of a number of instances of damaged wheels on Class 175 units, the entire fleet was temporarily withdrawn from service for safety checks. After further investigation, it was found that a track fault between Newport and Cwmbran had caused wheel damage to several trains, not only Class 175s but also some Class 158s. • On 21 December 2019, unit 458519 was involved in a collision with a car between Wokingham and Bracknell. Nobody was seriously injured. • 16 October 2020, a Dutch ICNG unit was being towed from Poland on delivery to the Netherlands when the train derailed at Dreileben, Germany. The driver of the locomotive hauling the train was injured. • Class 175 units have caught fire in 2004 at Preston (175008), 2009 at Prestatyn, 2011 at Manchester Piccadilly, 2017 both at Shrewsbury (175109) and between Chester and Crewe, 2018 at Deganwy, and in 2019 both near Pontrilas (175107) and at Gowerton (175102). • On 8 February 2023, Transport for Wales Rail unit 175008 was travelling from Holyhead to Cardiff Central when the North Wales Fire and Rescue Service and Network Rail were alerted to a fire aboard the train. This was followed by two further fires, both at Wilmslow, on 22 February and 1 March 2023. All three fires were attributed to a build-up of "debris, leaf litter, and other contaminants" in the units' under-floor engine bays; CAF, who had taken over Chester Traincare Centre from Alstom, had stopped periodic underframe cleaning of the units, and had to implement a remediation programme. Acknowledging that the three incidents in quick succession would "raise concerns", TfW Rail decided on 2 March to temporarily withdraw from service all Class 175 units that had not been through the cleaning programme. This caused disruption to TfW operations, though the level of disruption reduced in the following days as cleaned units returned to service. A further remediation includes replacement of the engines' intercoolers. == Gallery ==
