Security and technical upgrade to the Karavanke railway tunnel
The nearly 8-kilometre-long Karavanke tunnel is one of many tunnels and galleries on the Jesenice-Sežana line, also referred to as the Bohinj line, which was put into service in 1906.
Due to deterioration, the tunnel is in very poor condition and, furthermore, existing tunnel equipment fails to comply with the modern traffic and fire safety standards applicable to European core networks.
Within the scope of the security and technical upgrades, a plan is in motion to remove the double-track line in the tunnel and build a single-track line, restore the damaged parts of the structure, arrange drainage and the catenary and to set up an intervention corridor for signalling, safety and telecommunication devices as well as systems to ensure fire safety in rail traffic and for safe and efficient rescue in case of accidents.
