Design and features of Coradia Stream trains
The Coradia Stream train features a modular design that allows operators to select the configuration as per their requirements. It can operate on non-electrified lines using emission-free traction systems.
The trains can be designed with variable seating configurations, expandable bicycle compartments, or spacious multi-purpose sections.
The single-deck, bi-directional 3kV electric trainset is energy efficient, and features a propulsion system that includes four traction motors.
The Alstom Coradia Stream trains can operate at a maximum speed of 200km/h. With an access height of 600mm, the trains provide barrier-free access to passengers.
Alstom Coradia Stream interiors
The Coradia Stream features modular interiors, which can be modified to meet the requirements of different seasons. The trains can be customised to house bike racks, food and beverage dispensers, multimedia spaces, and work or relaxation zones.
The interior and seating configurations can be customised to create additional seats for longer journeys, or optimise the standing room for shorter journeys.
The vehicles feature wide windows that allow for increased light, space, and comfort. Furthermore, onboard services such as infotainment, audio, and video enhance the experience of passengers. Video surveillance facilities are installed in the train to provide increased safety.
The trains also feature a real-time passenger information system, WiFi, power sockets, and LED lighting.
Coradia Stream variants
The four-car version, which has 420 seats, comprises two double-deck control cars, and two single-deck middle cars. The five-car configuration includes an additional double-deck middle vehicle, and can accommodate 540 seats.
The capacity can be increased to 960 seats when the four and five-car carriages are arranged in a double traction combination.
The middle cars of the double-deck vehicles provide ramp-free access for passengers with reduced mobility.
The Coradia high-capacity version combines single and double-deck coaches to provide optimum accessibility, capacity, and flexibility. It provides up to 15% more space when compared to the existing vehicles serving the Main-Weser Express route.
Contractors involved
Teleste, a technology company based in Finland, was selected to provide an onboard solution including passenger information systems, video surveillance, intercommunication, and public address systems. It will also provide full-colour RGB LED information displays.
The entire onboard solution will be deployed aboard 31 Alstom Coradia Stream trains, ordered by FERROVIENORD.
Dassault Systèmes received a contract to provide the 3DEXPERIENCE virtual product configurator platform, to Alstom, to accelerate the delivery of the trains to Trenitalia. The platform provides Trenitalia with real-time visualisation of digital variants of full-fledged trains, before they are built.
