Built for Safety

CCTV & Real-Time Monitoring

Continuous surveillance and 24/7 monitoring by the Operation Control Centre (OCC) keep stations secure.

Police Patrol

Regular patrols ensure safety and security across all stations.

Help Points

Located at platforms, providing immediate two-way communication with the OCC in case of emergencies.

Automatic Platform Gates (APG)

Gates prevent access to the tracks until the train arrives, ensuring safe boarding.

Train Protection & Supervision

Automatic Train Protection (ATP) ensures safe train movement by preventing overspeed and collisions while Automatic Train Supervision (ATS) supervises train operations to ensure the services run according to the planned routes and schedule.

Power Reliability

Backup systems on trains provide lighting, ventilation, and communication during emergencies.

Help Points

Available inside trains, connecting passengers directly with the OCC.

Comprehensive CCTV Coverage

Designed in compliance with EN 15227 standards, ensuring enhanced structural safety during collisions.

Fire Safety Standards

Trains are designed with a 30-minute fire barrier and utilize non-combustible, non-dripping, and low energy release-rate inflammable materials to mitigate fire risks.

Train Crashworthiness

Designed in compliance with EN 15227 standards, ensuring enhanced structural safety during collisions.

Emergency Walkway

Provides a safe evacuation route to the nearest station during emergencies.

Fail-Safe Systems

Redundancies are built into critical track equipment, ensuring safety and continuous operation even in case of failure.

Condition Monitoring

Continuous checks ensure tracks and equipment remain safe and operational at all times.

Safe Materials

Our trains use low smoke, halogen-free, non-combustible materials to enhance passenger safety.

Fire-Resistant Interiors

Non-splintering, fire-resistant materials ensure a safer environment inside each carriage.

Advanced Detection

Equipped with fire and smoke detection systems, trains alert the Operation Control Centre automatically in emergencies.

Emergency Equipment

Each carriage is fitted with at least two fire extinguishers for quick access during an incident.
