Alstom Coradia Continental

The Alstom Coradia is a family of diesel multiple units, electric multiple units, and unpowered rail cars for intercity and regional service manufactured by Alstom, with variants operating in Europe, North America, and Africa.

Design

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. The standard variants of the train are fitted with a regenerative braking system. The Coradia can also be equipped with a variety of communication and signalling systems, including national automatic train protection (ATP) and European Train Control System (ETCS).

The Coradia is designed to offer a high degree of comfort for passengers. The design of the interior incorporates a modular philosophy; as standard, the passenger compartment features ambient lighting, luggage racks and storage areas, as well as partition walls located between the foyer and the seating areas. Each seat can be equipped with electrical sockets, individual lighting, and various audio and video systems; both the pitch and configuration of the seats are customisable to meet the operator's requirements. The internal fittings can be easily redistributed, being typically mounted onto purpose-built slots. Amongst the options available for customisation are equipment such as vending machines, in-train ticketing dispensers, and built-in internet provision; specialised accessibility facilities for disabled passengers can also be installed.

Coradia range

The Coradia range of regional trains includes the ''Coradia Duplex'', ''Coradia Lint'', ''Coradia Continental'', ''Coradia Polyvalent'' and ''Coradia Nordic'' variants. Alstom has also developed the ''Coradia Meridian'', specifically for Trenitalia and other regional operators in Italy. The Coradia Continental is an EMU operated as either three, four, five or six-carriage sets; up to four train-sets can be joined during peak times. The traction system is roof-mounted, freeing up room for a more spacious interior. Developed for German and other European markets, the Continental complies with the International Union of Railways (UIC) loading gauge standard and is suitable for platform heights of .

The Coradia Duplex train is a double-decker EMU operated in two to seven-carriage sets; furthermore, up to four train sets may be coupled together for a maximum length of 12 carriages. The Duplex range includes two models, one developed and used for TER services in France (designated Class Z 26500) as well as by Chemins de Fer Luxembourgeois ( designated CFL 2200), while the other is used in Sweden.

The Coradia Nordic is a wider body train, specifically developed for the large gauge standard commonly used in Northern Europe, and is available in configurations of four, five or six-carriage EMUs. To enable its use during the harsh winters common to Scandinavia, it can be operated at temperatures as low as and stored at temperatures as low as . To create space for passenger amenities and seating, its traction equipment is mounted on the roof.

The Coradia LINT, originally designed by Linke-Hofmann-Busch before its acquisition by Alstom, is a diesel-powered light train, somewhat similar to the Siemens Desiro and Bombardier Talent. It is available in configurations of one, two, and three-carriage sets; up to three such trainsets can be attached together. The propulsion system of the LINT features a diesel powerpack mounted to the underframe of the carriage to maximise space in the low-floor section. The design reportedly complies with the latest European environmental standards. It is used by a number of railways in Germany (DB class 640 and 648), the Netherlands, and Denmark.

The Coradia Polyvalent is the latest variant in the Coradia family. It can operate at a maximum speed of in electric or bi-mode at voltages of 25 kV and 1.5 kV; a cross-border version capable of operating at a voltage of 15 kV, suitable for the German and Swiss rail networks, is also available. The low integrated floor of the carriages provides improved accessibility and a high level of visibility to passengers. To restrict vibrations and noise levels, motorised bogies are placed at both ends of each carriage.

Operators

Europe

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 15-year full-service maintenance agreement, was placed by the Danish state-owned DSB for 100 Coradia Stream IC5 electric trains, and is valued at ; DSB expects to buy a total of 150. 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. In May 2014, the Régiolis train was introduced by the ARF (Association of French Regions), SNCF and Alstom at the Vaugirard station in Paris. As many as 182 Régiolis trains have been ordered by 12 French Regions. SNCF ordered 14 hydrogen trains in 2021.

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. In May 2014, Alstom delivered the first of 24 modernised Lints to Germany's Lower Saxony State public transit authority Landesnahverkehrsgesellschaft Niedersachsen (LNVG). In April 2014, the company agreed to supply six new Coradia Lints to LNVG; that same month, a €150 million contract for 29 Coradia Continental electrical trains was signed by Verkehrsverbund Mittelsachsen (VMS) in Central Saxony, Germany.

During December 2015, Hessische Landesbahn placed a €160m contract for 30 Coradia Continental EMUs, these are intended to be run on the Südhessen-Untermain network. In March 2016, Transdev placed an order for 28 Coradia Lints for operation in Augsburg, Germany. DB Regio placed a €40 million order for eight Lints in April 2016.

Italy

In September 2012, Alstom received a €67 million order from Ferrovie Nord Milano (FNM) for ten additional Coradia Meridian regional trains. Alstom had delivered 14 trains to FNM under the agreement by 2013. Ferrovie dello Stato ordered a further 70 Coradia Meridians from Alstom in November 2012. The Coradia has been used by Trenord for RegioExpress (RE) and for Malpensa Express service with the airport configuration Convoglio Servizio Aeroportuale (CSA).

Coradia Stream trains are operated by Trenitalia, Trenord, Ferrotramviaria, Trasporto Ferroviario Toscano and TUA.

Netherlands

The Alstom Coradia LINT, formerly also known as "Syntus LINT", had been used by Keolis (formerly known as Syntus) for regional transport. Arriva still operates LINT train sets on the mostly unelectrified Zutphen-Hengelo-Oldenzaal (ZHO) route.

Nederlandse Spoorwegen (NS) introduced its new NS Intercity Nieuwe Generatie, which is based on the Alstom Coradia Stream, in April 2023. By 2025 these new trainsets had largely replaced the currently aging ICMm trainsets. In addition these new trainsets will replace the current BeNeLux trains from Amsterdam to Brussels.

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 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.

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. Several more contracts have been signed for other Swedish operators, principally Skånetrafiken in Skåne County. In February 2015, Skånetrafiken placed an order worth approximately €150 million for 25 Coradia Nordics. Both the Continental and Nordic varieties were originally marketed as ''Coradia Lirex''.

A version of the Coradia Duplex, the SJ X40, used by SJ AB, was originally supposed to be used for regional traffic around Mälaren in Sweden. However, SJ AB has also deployed the train on an intercity route between Stockholm and Gothenburg.
