Cetrovo, the new metro from CRRC is a high-speed, environmentally friendly, intelligent design with a speed up to 87 miles per hour.
It is designed with a carbon fiber composite car body, silicon carbide permanent magnetic traction system, and an active radial and fully active suspension system bogie. The adoption of a split-mould modular design approach offers precision mouldings. The adoption of a hybrid sandwich structure for the side walls ensures they are light and stiff. Interiors and floors rely on ultra-light, ultra-strong environmentally friendly materials.
The train is 13 percent lighter, the noise is 3 dB lower and the energy efficiency is improved by 15 percent. It is an unmanned smart metro train, featuring flexibility in configuration.
The passenger information system is integrated with a search engine, entertainment and shopping channel system and can be accessed via smart screens in the windows.
An online operation and maintenance monitoring system provides real-time data to the operation and maintenance center, transforming the maintenance approach to improve rolling stock availability. By integrating and interfacing with information such as axle temperature, vibration, lateral stability, infrared pantograph monitoring, bogie infrared monitoring, and more, monitoring of on-board parameters is possible. In-motion and smart detection offers early warnings providing a train-based active maintenance system.
