siemens.com/mobility Eurostar e320 high-speed trains for Eurostar International Limited
In December 2010, Eurostar International Ltd. awarded Technical Data Siemens a contract for ten interoperable 16-car high- speed trains. These trains are based on Velaro®, the Maximum operating speed 320 km/h world’s most highly diversified high-speed platform. Train length 400 m Starting in 2015, these trains will be added to the existing Voltage system 25 kV AC and 1.5 / 3 kV DC Eurostar fleet operating on the London–Paris–Brussels line Traction power 16,000 kW running through the Eurotunnel between Great Britain and the European continent. Brake systems Regenerative, rheostatic, pneumatic Rated at 16,000 kW, the Eurostar e320 (Class 374) reaches Track gauge 1,435 mm a top speed of 320 km/h.

With its improved capacity, the constant passengers to find their seats as quickly as possible. evolution of its systems in terms of reliability and lifecycle costs, and the experience of the people who build it, Proven safety it represents the current benchmark for high-speed trains Having undergone continuous further development since with distributed traction. the first generation, the Eurostar e320’s bogies provide perfect guidance and thus outstanding riding comfort. Even more important than rapid acceleration is rapid deceleration. The Velaro’s electric brake automatically distributes braking energy between the pneumatic and regenerative braking systems. The optimized body-shell and train concept complies with the EN 15227:2008 standard for collision safety. A crash energy absorption system and crash elements protect passengers and crew in the unlikely event of an accident.
