The Montenvers Railway suspended for 12 hours Last Friday, late morning (12.30h), a train broke down on the Montenvers railway line. More than 1,000 people were at the Montenvers station. It took the Compangnie du Mont-Blanc 5 hours to safely return everyone to Chamonix. The next day, everything was back to normal with the resumption of a full service. Normal Route of the Grandes Jorasses closed The Mayor of Courmayeur decreed a bylaw to prohibit the normal route des Grandes Jorasses, by the Refuge Boccalate. Forecasts of falling blocks of ice at the Serac Whymper are very serious and pose a huge danger to climbers and hikers who want access to the refuge.
