The carriage, Named CETROVO 1.0 Carbon-Star Fast Rails, is developed in collaboration with Qingdao Metro Group and other local partners, replacing metals with carbon fiber in its carriage body (25% weight reduction), bogie frame (50% weight reduction) and other primary loading structures, deducing the overall weight of the carriage by 11% and cutting down the operational energy consumption by 7%.

Being lighter does not only increase the carriage’s driving performance by lessening abrasion of wheels and rails, but also reduces the cost for maintenance and repairing. In addition, by adopting carbon fiber, the strength of carriage is greatly enhanced, it becomes more adaptive to the changing of severe environment conditions, and the overall operational cost during the entire life-cycle is largely reduced.

The carriage has now passed the internal type certification, and will be put into operation, according to the plan, at Qingdao’s Metro Line 1.
