World's first carbon fiber metro train begins service in China's Qingdao

The world's first carbon fiber metro train named "CETROVO 1.0 Carbon Star Express," independently developed by China, has begun passenger service on the Metro Line 1 of Qingdao, east China's Shandong Province on Friday.　

Compared with traditional metal metro vehicles which are built with steel and aluminum alloys, the carbon fiber metro train is approximately 11 percent lighter, with operational energy consumption reduced by 7 percent. Each train can reduce carbon dioxide emissions by 130 tons annually.　

The debut of the carbon fiber metro train marks a groundbreaking upgrade in China's metro train lightweight technology, according to the metro train's developer.
