The first passenger train in the world made mostly of carbon fiber began carrying commuters this month in China. The Cetrovo 1.0 Carbon Star Express, developed by the state-owned company CRRC Qingdao Sifangis operating on the new “Line 1” of about 60 kilometers with 41 stations in Qingdao.
This innovative train represents an important step forward in ecological transport. Its construction in carbon fiber, the same material used by car manufacturers supercar, makes it about 11% lighter than conventional steel trains. This translates into energy consumption reduced by 7%equivalent to a saving of 130 tonnes of CO2 emissions.
In addition to the environmental benefits, carbon fiber offers other significant benefits. The material is five times stronger than steel for the same weight, ensuring greater rigidity and impact resistance. Passengers can look forward to it a smoother journey and silent thanks to fewer vibrations.
During last year’s testing, the train demonstrated impressive performance, reaching speeds in excess of 140 km/h, well above the 80 km/h average of current Chinese metro systems. It is also equipped with advanced features such as automated operation and cutting-edge safety systems.
If the Carbon Star Express is successful, could pave the way for the widespread use of carbon fiber composites in public transportation projects in China and other countriespotentially replacing steel as the primary material. This would mark a significant shift towards more efficient and sustainable means of transport.
