OPTIMAL DISTANCE BETWEEN EVACUATION CROSS PASSAGES IN RAILWAY TUNNELS

This article provides a concise analysis of regulatory documents concerning fire protection for the underground infrastructure of railway tunnels. Special attention is paid to the distance between evacuation cross passages, which is a critical factor for the evacuation of passengers with reduced mobility during a fire. The development of a dedicated regulatory document is proposed, one that would account for all the specific aspects of ensuring the safe evacuation of a large number of people (train passengers) from a tunnel.
