Technical Specifications

The Coradia Stream is an articulated, low-floor Electric Multiple Unit (EMU) designed for high performance and accessibility. The rolling stock’s primary innovation is its modularity, allowing operators to specify train length, interior layout, and dedicated zones for bicycles, luggage, or passenger work areas. Propulsion is delivered via distributed traction motors, providing rapid acceleration and energy efficiency, with options for bi-modal operation on non-electrified lines. The platform is compliant with the latest European Technical Specifications for Interoperability (TSI), ensuring seamless operation across borders.

Passenger-facing systems are integrated into a modern digital architecture. This includes real-time passenger information systems (PIS), onboard Wi-Fi, power sockets, and advanced LED lighting. A key design feature is the 600mm access height, which provides barrier-free entry from standard European platform heights, enhancing accessibility for passengers with reduced mobility. The trainsets are also equipped with comprehensive video surveillance systems to ensure passenger security. Maintenance is streamlined through long-term service agreements (up to 30 years), leveraging predictive maintenance and Alstom’s digital monitoring platforms to maximize fleet availability.

Key Takeaways

Mass Customization at Scale: The Coradia Stream’s modular platform proves a successful model for delivering tailored rolling stock solutions that meet specific regional demands without the cost of bespoke engineering for each order.
Enhanced Operational Efficiency: A combination of high capacity (up to 960 seats in double traction), a top speed of 200 km/h, and energy-efficient systems provides operators with a significantly lower total cost of ownership and improved service frequency.
Pan-European Collaboration Model: The project’s success, involving development and manufacturing across France, Germany, Italy, and Poland, alongside specialized technology partners, demonstrates the effectiveness of a distributed, cross-border supply chain for complex infrastructure projects.

Frequently Asked Questions (FAQ)

What makes the Alstom Coradia Stream train unique?
The Alstom Coradia Stream’s primary unique feature is its highly modular design. This allows railway operators to customize almost every aspect of the train, from its length and seating layout to specialized areas for bicycles, luggage, or work zones, making it adaptable to a wide variety of regional and intercity routes.

Which countries use the Coradia Stream train?
As of 2026, the Alstom Coradia Stream is in service or on order in several European countries, most notably the Netherlands (as the ICNG), Italy (as ‘Pop’ and ‘Donizetti’), Germany (for networks like the Main-Weser Express), and Denmark (for DSB’s ‘Fremtidens Tog’ fleet).
