build about 24.7km long high-speed railway tunnel between Prague and Beroun (Krása et al. 2007). A preliminary design was completed in 2007, construction start is planned for 2011, and the project is expected to be completed in 2016. The tunnel is expected to have two single-track tunnels connected with cross-passages with spacing of 400m.

By being in a closed area, railway tunnels present a higher risk for the safety of train passengers and on-board staf during operations. Fire, derailment, long stops and other accidents require preventive safety measures to minimise the risk and increase the comfort of passengers.

This TSI concerns the control command and signalling, infrastructure, energy, operation and traffic management, and rolling stock (locomotives and passenger units) subsystems. It applies to new, renewed and upgraded tunnels which are located on the rail network of the European Union.

Railway tunnel: A railway tunnel is an excavation or a construction around the track provided to allow the railway to pass for example higher land, buildings or water. The length of a tunnel is defined as the length of the fully enclosed section, measured at rail level.

Nov 24, 2022 · Shallow tunneled crossings under live highways and operating railways impose more significant risks to the public and potential for damage to a range of third-party persons and property compared to most other tunneling projects.

The main risks that are considered in tunnels are fire, collision and derailment. Because of their potentially catastrophic consequences, fires in passenger trains are seen as the major risk and the set of measures proposed focuses on this type of accident.

In comparison with rail tunnels, guidelines for the structural fire protection of road tunnels are relatively well developed. The International Tunnelling Association (ITA) has issued joint guidelines with the World Road Association (Lacroix and …
