New Chinese Metro Standard Boosts Green, Smart Track Tech – Industry Ready for Upgrade
China's New Metro Standard GB/T 7928–2025: A Call for Advanced Vibration and Noise Control
China has released a new national standard for metro vehicles, GB/T 7928—2025, effective May 1, 2026. The rules push for quieter, lighter trains with better acceleration and smart monitoring – a direct call for advanced vibration and noise control.
A Clear Signal for Industry Innovation
For companies like Changmei Technology, this is a clear signal. The new standard asks for lower noise limits, reduced energy use, and lightweight design. Changmei already supplies a full range of track vibration solutions:
• Floating slab track mats
• Resilient fasteners
• Rail dampers
• Tuned composite spring isolators
These products are designed to cut structure-borne noise and vibration – exactly what the new metro rule targets.
Smart Monitoring Integration
The standard also requires smart terminals for condition monitoring, communication, and video. Changmei's products, such as broadband rail damping noise reducers and rail corrugation inhibitors, can easily integrate with such monitoring systems. This allows real-time tracking of track performance, helping metros run smoother and quieter.
In short, the 2025 standard matches Changmei's green, intelligent, and low-noise philosophy. The company's proven track technology is ready to help metro lines meet the new requirements – reducing noise for communities and saving energy for operators.
