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

China's Xinhua News Agency reported that CRRC Qingdao Sifang 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 the overall weight of the train to less than 11% compared to traditional subway trains.

Mr. Liu Jinzhu, Design Director of CETROVO 1.0, said that a subway like CETROVO 1.0 will help reduce energy consumption by about 7%, which means reducing CO2 emissions by up to 130 tons per year, equivalent to planting about 6.7 hectares of trees.

In addition, the use of carbon fiber materials helps CETROVO 1.0 increase rigidity, prolong the life of the ship's structure as well as improve the ship's adaptability to many different environmental conditions, thereby reducing maintenance costs.

This is thanks to the lighter weight of the train when made from carbon fiber, thereby minimizing the mass transferred from the train to the wheels onto the rails, helping the wheels to be less corroded as well as creating less noise during movement, bringing significant quietness to passengers.

Meanwhile , the Global Times newspaper revealed that the CETROVO 1.0 subway is designed to run at a maximum speed of 140km/h, significantly faster than the average speed of 80km/h of other subways.

Furthermore, CETROVO 1.0 is equipped with fully autonomous driving mode and can easily enter and exit curves and narrow roads. The train also has an intelligent anti-collision warning system and an obstacle detection system that can automatically send warning information and stop the train in case of emergency.

CETROVO 1.0 has completed factory testing and is expected to go into operation in Qingdao this year.
