Overview
- Around 13:00 on September 28, a three-cubic-meter boulder detached above Pradello, struck the rail line and rebounded onto the northbound SS36 without hitting vehicles.
- The train driver triggered an emergency stop and the first bogie of the front carriage left the rails, yet no injuries were reported.
- Firefighters evacuated passengers using ladder trucks, with reports differing on the count between roughly 150 and about 500 people.
- Trenord suspended service between Lecco and Mandello del Lario, identified train 2824 as stopped between Lecco and Abbadia Lariana, and arranged replacement options.
- Crews removed the boulder and reopened one northbound lane before 19:00, while ANAS and geologists kept precautionary closures and inspections in place as rock-stabilization work continued on tracks recently renewed for Milano–Cortina 2026.
