Olmata Tunnel Upgrade

Preparatory works for the upgrade of the Olmata Tunnel to PC80 gauge, Rome–Cassino line

For the client RFI – Rome Territorial Infrastructure Operations Department, Sveco is a member company of the temporary joint venture led by MI.COS (contractor), operating under an RFI framework agreement for the maintenance of civil works in tunnels.

The project involves the execution of the works required in preparation for the upgrade of the Olmata Tunnel to PC80 gauge, on the Rome–Cassino line, based on the detailed design developed by ETS.

In 2024, the joint venture was awarded the completion works, carried out while the railway line remained in service, with the activities divided between Sveco and MI.COS: micropiles inside the tunnel and new edge beams connected to the existing tunnel sidewalls.

The works

• micropiles inside the tunnel
• new edge beams connected to the existing sidewalls
• final reinstatement of the track ballast
• vegetation clearance and removal of the ballast
