Alstom Coradia
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 and an electric multiple unit 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 and European Train Control System.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 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 as well as by Chemins de Fer Luxembourgeois, 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, 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.
The Coradia MAX mixed single and double decker 5 car and 3 car units for DB Regio AG for use originally in-between Hamburg and Rostock/Lübeck. CFL has also ordered a numer as the 2400 Series
