China launches ultra-light subway train with carbon fiber frame and body

According to China's Xinhua news agency, Qingdao Sifang CRRC Group launched the CETROVO 1.0 subway train in Shandong province on June 28. The train's frame and body are made of carbon fiber, reducing its overall weight by less than 11% compared to traditional subway trains.

According to Liu Jinzhu, design director of CETROVO 1.0, a subway train like CETROVO 1.0 will help reduce energy consumption by about 7%, which means a reduction in CO2 emissions of up to 130 tons per year, equivalent to planting about 6.7 hectares of trees.

Furthermore, the use of carbon fiber materials enhances the rigidity of the CETROVO 1.0, extending the structural lifespan of the vessel and improving its adaptability to a wide range of environmental conditions, thereby reducing maintenance costs.

This is achieved thanks to the lighter weight of the train, which is made from carbon fiber, thereby minimizing the weight transferred from the train to the wheels and onto the tracks. This results in less wear and tear on the wheels and less noise during movement, providing a significantly quieter experience for passengers.

Meanwhile, the Global Times once revealed that the CETROVO 1.0 subway train is designed to reach a maximum speed of 140 km/h, significantly faster than the average speed of 80 km/h of other subway trains.

Furthermore, the CETROVO 1.0 is equipped with a fully autonomous driving mode and can easily navigate curves and tight turns. The train also features an intelligent collision avoidance warning system and an obstacle detection system capable of automatically sending warnings and stopping the train in emergency situations.

CETROVO 1.0 has now completed its factory testing and is expected to begin operations in Qingdao this year.
