Recently, the review meeting for the "Independent Relays for the Development and Testing of Series Chinese Standard Subway Trains" organized by CRRC Corporation Limited was successfully held at Hongfa. Leaders of rail and subway companies from multiple cities, two experts from the China Electrical Relay Standardization Committee, as well as relevant leaders from China CRRC's six major OEMs and Hongfa, attended the meeting. Professor Xu Zhihong from Fuzhou University served as the leader of the expert group and presided over the meeting.

After evaluation, the expert group highly praised Hongfa's self-developed rail transit products. The expert group believes that Hongfa's self-developed rail transit products meet the requirements of the development team, comply with standards, and meet the conditions for loading and operation. The review meeting was a complete success. The holding of this review meeting injects strong momentum into the implementation of the project, promotes the large-scale production and application of domestically produced and independent relay products in the field of rail transit, and ensures the safe development of China's urban rail transit.
