Other informations:

Smoke and passenger evacuation scenarios were prepared for all possible negative situations in Kadıköy - Kartal Metro and tested by making simulations about these scenarios. The system is continuously monitored and controlled by the total 831 camera in the stations.
The signaling of the line and the storage area has a continuous communication-based Motion Block system. The signaling system is Thales CBTC system and the trains are able to operate without driver. Since trains are equipped with a mechanic's cab, and there is no operating mode without a driver, there are no trains on the trains. However, in cases where the passenger is not present (empty train is sent to the parking zone or warehouse area or from the warehouse and parking area to any part of the main line), it is possible to use completely without driver.
All the equipment used in the subway are selected from materials that are highly resistant to heat and do not emit toxic gases. There is a reliable smoke control and evacuation system, which is fully compliant with NFPA standards, which is fully proven to be safe for people to evacuate in case of fire.
The energy supply of the whole system at Kadıköy - Kartal Metro is made from a separate point 3. The OG ring is the 34,5 kV system. If all three feed points are disabled, the 2 generators can be activated and all the trains within the tunnel are transported one by one to the nearest station. When the generators are switched on, the supply of essential loads in the station continues. Essential loads must be disabled for this. In case the power supplies are interrupted and the generators fail and fail, the lighting system and electronic control systems can be supplied by means of uninterruptible power supplies for 3 hours.
