Project Profile: Siemens Viaggio Comfort High-Speed Train Platform

The Siemens Viaggio Comfort is a highly adaptable high-speed intercity passenger rolling stock platform, engineered for operational flexibility and energy efficiency. Developed by Siemens Mobility in collaboration with Škoda Transportation, this platform is deployed globally in various push/pull configurations, notably as the ÖBB Railjet and ČD Railjet fleets. Its modular design allows for extensive customization to meet diverse network specifications and passenger service requirements.

Technical Specifications

The Viaggio Comfort platform’s core technical strength lies in its modularity and multi-system interoperability. The coaches are non-powered and designed for push/pull operation, typically paired with high-performance locomotives like the Siemens Vectron or Taurus. This configuration allows for rapid turnaround times at terminal stations without needing to reposition the locomotive. Each car body is a pressure-sealed, lightweight steel construction measuring 26.1 meters, designed to minimize aerodynamic resistance and energy consumption. The platform is engineered for compatibility with all four major European electrification systems (15 kV AC, 25 kV AC, 1.5 kV DC, 3 kV DC), enabling seamless cross-border service. Onboard systems include advanced climate control, electronic passenger information displays, Wi-Fi, and power outlets. Safety architecture is a priority, with reinforced crash-absorption elements in the front-end control car and extensive video surveillance systems.

Key Takeaways

• Modular Flexibility for Diverse Markets: The platform’s primary advantage is its customizable nature, allowing operators to configure trainsets with varying numbers of cars and interior layouts (economy, business, restaurant) to precisely match route demand and service strategy.
• High Operational Efficiency: The combination of aerodynamic design, energy-optimized standby functions, and push/pull operation with multi-system locomotives minimizes energy use and reduces station dwell times, enhancing network efficiency.
• Proven Interoperability and Reliability: Widespread deployment by major national operators like ÖBB and ČD across complex European corridors has demonstrated the platform’s robustness, reliability, and capability for seamless cross-border high-speed rail service.

Frequently Asked Questions (FAQ)

What makes the Viaggio Comfort train platform unique?
The Viaggio Comfort platform is unique due to its modular “building block” design and its use in fixed push/pull trainsets. Unlike traditional trainsets, operators can easily customize the length and interior class configuration. This flexibility, combined with its proven high-speed performance and multi-system electrical compatibility, makes it a highly versatile solution for intercity rail operators like Austria’s ÖBB, which brands its fleet as the “Railjet”.

Who manufactures the Viaggio Comfort trains?
The Viaggio Comfort train platform is primarily manufactured by Siemens Mobility, a global leader in railway technology. The development and production often involve collaboration with other major rolling stock manufacturers, such as Škoda Transportation, which has been a key partner in producing cars for operators like České dráhy (Czech Railways).
