Fully adopt Chinese standards! This type of subway train made its debut in Guangzhou | Subway | Standard
On the 29th, the A-type Chinese standard subway train with a speed of 80 kilometers per hour was released in Guangzhou, Guangdong and will be put into operation on the Guangzhou subway.
The A-type standard train was jointly developed by Guangzhou Metro Group and CRRC Changke Co., Ltd. It has achieved significant breakthroughs in key core technology research and development. Key systems such as the vehicle body and bogie fully adopt Chinese standards, and 28 key components such as bearings, couplings, chips, and high and low voltage electrical components have achieved autonomy, significantly reducing train maintenance and repair costs, and promoting industrial scale and standardization.
The Chinese standard subway train is a new and technologically leading product platform that is led by Chinese standards, adopts standardized, modular, and serialized design concepts, inherits existing subway train application experience, and independently develops based on the needs of domestic subway users. Subway trains can be classified into various models such as A, B, and C based on their vehicle width.

Green and energy-saving are important driving directions for standard trains. The train adopts a permanent magnet traction system and comprehensive energy-saving control technology. Compared with traditional asynchronous traction systems, the whole vehicle can save more than 15% energy; Adopting a lightweight high-frequency auxiliary inversion system, each train can reduce weight by more than 600 kilograms, further reducing operational energy consumption.
