For the Sofia station, are there not dangers or hazardous to only have elevators? In case of fire, terrorist attack etc.

We have the requirement to have two separate ways of emergency exit. The first option are the elevators, the second will be regular stairs. The elevators and stairs are separate fire cells. As a third option it is possible to use the servicetunnel and acesstunnel in order to evacuate. In case of a loss of electricity there will be reserve power supply located in the servicetunnel.


How will be the emergency exit under a fire, explosion, when lifts or electricity will be off to work? For instance, in station Sofia, if there is cut of electricity, and not able to use lifts.

What if you have a fire in the elevator?

There will be smokedetectors in the shaft and an elevator will go to a floor plan for evacuation. Beside the elevators there will also be two stairwells in the station for evacuation.


I understand fire can be managed, but what if there is an attack, as in London for example, will that not be dangerous?

We can not be specific about this question but different kind of scenarios has been taken into account when designing the station.
