The purpose of having many mechanical systems in stations and tunnels; In rail systems, to ensure passenger safety and not to disrupt the transportation.

OKRAY; provides the necessary consultancy service for a system design in international standards.

Platform Separator Door Systems, being one of the most important components of safety travel on driverless metro lines; It separates the passenger waiting area from the rail line on the platform. Hence, it is an electronically controlled and monitored system that prevents contact between the moving vehicle and the passenger waiting on the platform.

Air conditioning systems that operate to clean contaminated air in tunnels and stations also perform the task of evacuating smoke and keeping it away from people in case of an emergency. Reversing the air flow when necessary, ensures that no polluted air remains in the tunnel and station.

Fire Detection and Alarm Systems are the first requirement to be able to respond to an emerging fire. These systems, which detect the fire at the start-up and activate the warning systems before the flames rise, the working principle is generally provided by the smoke detectors detecting the heat change through the smoke or heat sensors.

Drainage Systems, excavation water, rain water, flood water, surface water and seepage water etc. It is used to drain water smoothly and easily.
