In modern urban rail transit systems, safety, efficiency, and passenger experience are more important than ever. Platform Screen Doors have become a key component in advanced subway and metro infrastructure worldwide, helping operators create safer, quieter, and more energy-efficient stations.

Platform Screen Doors (PSD) are automated glass barrier systems installed along the platform edge of metro or railway stations. These doors synchronize precisely with train doors, opening only when trains stop correctly at the platform. PSD systems are widely adopted in major metro networks across Asia, Europe, and the Middle East due to their outstanding safety and operational benefits.

Enhanced Passenger Safety

Platform Screen Doors create a physical barrier between passengers and railway tracks, significantly reducing accidental falls, unauthorized track access, and safety incidents. They are especially valuable in high-density stations with heavy passenger traffic.

Intelligent Train Synchronization

Advanced PSD systems integrate seamlessly with signaling and train control systems. The doors open and close in perfect synchronization with train doors, improving boarding efficiency and reducing dwell time. Modern systems also support AI-based diagnostics and predictive maintenance.

Energy Saving & Climate Control

Full-height Platform Screen Doors help isolate station platforms from tunnels, reducing airflow exchange and minimizing air-conditioning energy consumption. This improves passenger comfort while lowering operating costs.

Improved Passenger Experience

Transparent tempered-glass designs provide a modern and premium station appearance while reducing tunnel noise and improving platform organization. Many systems now support passenger guidance displays, crowd monitoring, and accessibility information

Full-Height Platform Screen Doors

These systems extend from floor to ceiling, creating a fully enclosed barrier between platform and track areas. They are commonly used in underground metro stations with air-conditioning systems.

Half-Height Platform Gates

Also called Platform Edge Doors (PED), these systems provide safety protection without full enclosure, making them suitable for elevated or outdoor stations.

Customized PSD Solutions

Modern metro projects increasingly require customized configurations, including:

• Variable door spacing
• Curved platform compatibility
• Emergency escape doors
• Smart monitoring systems
• Integrated passenger information displays

• High-strength tempered safety glass
• Precise train-door synchronization
• Intelligent obstacle detection
• Emergency manual release system
• Low-noise sliding mechanism
• Anti-drag safety protection
• Remote monitoring and diagnostics
• SIL-certified safety control systems
• Long service life with minimal maintenance

Platform Screen Doors are widely used in:

• Metro systems
• Subway stations
• Airport people movers
• Automated rail transit
• High-speed railway platforms
• Smart city transportation projects

With increasing demand for automated and intelligent urban transit systems, Platform Screen Doors are becoming a global standard for modern railway infrastructure. Recent metro developments worldwide continue adopting PSD systems to improve operational safety, passenger comfort, and system efficiency.

As cities continue investing in smart transportation, Platform Screen Doors are evolving into intelligent integrated systems featuring AI monitoring, predictive maintenance, passenger flow analytics, and energy optimization.

A well-designed PSD system not only protects passengers but also enhances operational reliability, station aesthetics, and long-term sustainability for modern rail transit networks.
