Railway Tunnel Ventilation Systems

Railway Tunnel Ventilation Systems

Tunnel venti­lation systems of railway lines are primarly used to provide safe evacuation condi­tions for fleeing people in case of fire. They serve to transport toxic gases, smoke and heat out of the walkways and tunnels. 

Under normal operating condi­tions, the piston effect of moving trains in tunnels is used to provide fresh air to the tunnel system. Moving trains in tunnels produce pressure waves which propa­gates through the tunnel at sonic speed. The pressure waves affect the technical equipment inside the tunnel. Therefore, the design of the technical equipment needs to consider the load of the simulated pressure waves.

Hence, inves­ti­gating the air movement caused by trains is essential for a proper design process in modern railway tunnels.
