en.Wedoany.com Reported - Recently, a 120 km/h metro train equipped with an electro-mechanical braking system officially entered passenger service on Shenzhen Metro Line 11. This is the world's first metro train of this speed class to use electro-mechanical braking technology for commercial passenger operation.

This braking system, developed by CRRC after more than two years of rigorous multi-round verification and technical breakthroughs, is a new-generation braking system characterized by generational advancement, full electric drive, intelligence, and high performance. By replacing compressed air drive mode with direct electric drive, it achieves full electrification from control to execution, featuring rapid response, precise control, and high safety redundancy. It also possesses attributes such as a high degree of intelligence, lightweight design, and convenient operation and maintenance, representing an important innovative direction for train braking systems.

This braking system has passed China's first SIL4 certification for a 120 km/h rail transit electro-mechanical braking system product, demonstrating that the electro-mechanical braking system has a comprehensive safety R&D process control system covering requirements, design, verification, and operation and maintenance. The product's technical strength and engineering capability in the field of functional safety have met the highest international safety integrity level requirements, providing a more solid guarantee for safe train operation.
