Definition: The China Railway CRH5 is a high-speed electric multiple unit (EMU) train developed for use on China's railway network as part of the China Railway High-speed (CRH) series. It is based on the Alstom Pendolino ETR-600 platform, adapted for operation under Chinese conditions.
Overview: The CRH5 series was introduced in the mid-2000s as part of China's efforts to modernize its rail system and expand high-speed rail connectivity. Manufactured through a technology transfer partnership between CRRC Changchun Railway Vehicles (formerly CSR Changchun) and Alstom of France, the CRH5 was primarily designed for high-speed service on northern and northeastern routes, where it operates in colder climatic conditions. The train set is used on lines such as the Beijing-Harbin and Longhai corridors.
Etymology/Origin: The term "CRH5" follows the naming convention of the China Railway High-speed (CRH) series: "CRH" stands for China Railway High-speed, and the number "5" designates the fifth variant in the series, corresponding to the specific technological lineage and manufacturer collaboration. The "5" identifier was assigned to models derived from the Alstom ETR fleet, particularly the New Pendolino series.
Characteristics:
- Power type: Electric multiple unit (EMU)
- Maximum design speed: 250 km/h (155 mph)
- Operating speed: Typically 200–250 km/h (124–155 mph)
- Formation: Usually 8-car sets (can be coupled to form 16-car trains)
- Axle load: Designed to operate on conventional non-ballast tracks with adaptations for cold weather
- Climate adaptation: Equipped for operation in extreme cold, down to −40 °C (−40 °F), making it suitable for northern China
- Traction system: Based on Alstom’s ONIX IGBT–VVVF technology
- Bogies: Derived from the Alstom AG415/AG416 design with modifications for Chinese track specifications
The CRH5 does not feature active tilting mechanisms, despite its Pendolino heritage, as tilting was deemed unnecessary for the track geometry and operational requirements of the Chinese rail network.
