Fire detection in railway tunnels : full scale fire tests

The industry currently lacks a deep understanding of the performance of fire detection equipment in railway tunnels conveying both diesel and electrified trains which is necessary to enhance tunnel safety. A series of tests have been conducted over a six month period to identify the strengths and weaknesses of several fire detection systems and technologies. The main objective of these tests is to determine which system and technology, or combination, is the most responsive and effective in detecting railway tunnel fire events with minimal nuisance alarms and maintenance requirements. The fire detection systems tested include linear heat detectors, aspirating smoke detectors, flame detectors, and infrared radiation detectors. Each system was installed in an active railway tunnel and evaluated based on its relative performance under different scenarios of fire/heat/smoke and tunnel operation conditions.
