The president of CTIF, Milan Dubravac, greeted the participants of the meeting with the short foreword. The president thanked the members for the participation in the working group and he emphasized the importance of this group as it is very relevant technical commission and the issue of tunnels represents one of the biggest challenges for the firefighters worldwide.

CTIF vice president Martin Nekula stated that he had a discussion with his colleagues in the Czech Republic and that they are interested in new information and opinions regarding this group. It is important to have feedback from the other countries, it is necessary to share experience in order to elevate the issue of tunnels. 


  1. Responsibility for the group

If someone is interested in this topic and would be willing to take part in the group as a chairman or a secretary, they should provide their CV to Martin Nekula. Martin will ask member countries for the suggestions for the chairman and the secretary. It should be somebody who will be active and willing to lead the group as well as experienced in the area. Peter would consider to be a chairman.

  1. Internal activities in countries

In the Czech Republic there is one region where new railways will be built. The Czech Republic could use experience from other countries regarding this issue. 

  1. Lessons learned

High – speed rail and regulations

  • Requirements for high – speed tracks (dry lines, water, communication, ensure train voltage line, procedures – different rules in different countries)
  • Questionnaire – research on conditions
  • Regulations in the field of tunnel constructions
  • Legislation 
  • Statistic data – possibilities for sharing
  • Presentation in order to have comparisons for the member countries

Current approaches to risk assessment in tunnels

  • Modern methods and tools for risk analysis
  • Integration of risk assessment results into tunnel planning and operation

New technologies in road and rail tunnels

  • Innovative materials and construction techniques
  • Advanced detection and monitoring systems (e.g. sensors, AI, IoT)
  • Automated and intelligent control systems

New road and rail tunnel firefighting capabilities 

  • In the Czech Republic there are different procedures
  • Advanced extinguishing agents and technologies (e.g. water mist, foam extinguishing systems)
  • Confined space intervention strategies and tactics
  • Firefighter education and training

Technical requirements for the tunnels of the European high-speed system

  • Design principles and safety standards
  • Special technical equipment of high-speed line tunnels
  • Requirements for firefighting in the context of high-speed rail transport

Transnational solutions in the fire rescue services

  • Transnational cooperation
  • Collaboration with the HAZMAT commission of the CTIF is possible.

Development of new solutions through EU projects

  1. Discussion

All topics are very interesting. Peter thinks that a topic about transnational solutions in fire rescue services should be included, e.g. tunnels between two countries like the UK and France. How to work together on a transnational level. 

Martin suggests that next meeting should take place at the end of the year in October and in then it would be appropriate for the group to meet in person in 2025. 

Michael suggests location for the meeting in person at the Brenner Base Tunnel. This tunnel is one of the most interesting tunnels in regard with the topic. Peter says that meeting could be also arranged in Denmark at the construction area. Denis also invited members to Lyon-Turin tunnel. Then he proposed a topic regarding tunnel construction sites, especially underground sites. Transnational tunnels have specific regulations, and new solutions from the EU projects. Jörg said that Switzerland has a lot of the intercountry tunnels and a lot of experience with different kind of fire brigade regulations of those tunnels. He also invited group members to Switzerland. 

  1. Opportunities for collaboration


  2. Next meeting plan

Next virtual meeting should take place at the end of the year in October and in then it would be appropriate for the group to meet in person in 2025.

  1. Conclusion 

Regarding the conclusions the main directions of the group were set up. 

Next steps for the group include important tasks, mainly to vote the chairman and the secretary of the working group. 

Other issue to deal with is the platform for sharing knowledge, information, documents etc. It will be established on a non-conflict version of software available ideally in all countries. 

It was also suggested that meeting should be arranged for the members of the working group to meet in person in 2025 and also the date for next virtual meeting was planned on October.
