HUSK handles the complete implementation of PSD (Platform Screen Door) systems, built on international strategic partnerships and local technical expertise. We integrate global technology into national projects with in-house engineering, manufacturing infrastructure, and execution in compliance with metro-rail safety standards.

What are PSDs?

Platform Screen Doors are automated barriers installed along the edge of the platform, synchronized with the train doors. They ensure track isolation, passenger protection, and operational control of the fleet.

HUSK's Technical Scope

HUSK is responsible for every stage of the implementation, including:

• Technical and civil engineering and adaptation according to the station's layout and infrastructure
• Physical assembly and installation and integration with existing systems (CCTV, sensors, electrical and control networks)
• Preventive and corrective maintenance per the operating cycle
• Technical training for operations and management teams

Every project is executed based on a specific technical analysis, complying with national and international standards (ABNT, EN, among others) and the operational particularities of each line.

Operational Benefits of PSDs

• Increased safety: eliminates the risk of falling onto the track and unauthorized access
• Improved flow: reduces unplanned stops and improves train regularity
• Lower operational costs from failures and emergencies
• Infrastructure value gains through improved reliability and a more modern perception
