The article describes the installation and layout of auxiliary safety ventilation and power equipment on the Arlberg Tunnel. All electrical equipment is installed in rooms adjacent to parking areas so requiring no additional excavation and allowing maintenance without traffic interruption. Safety passages to the second tube are located at fire-fighting stations. These stations are separated from the traffic area for reasons of safety and noise insulation. Ventilation stations consist of underground caverns housing ventilation and electrical equipment with fresh air and exhaust structures located at the head of the shaft. The caverns were designed for the poor geological conditions expected which prevented large cross sections. Details are given of layout of caverns and ventilation systems. (TRRL)
