Initial news item, published on the 13th of August 2019:

On Sunday, the 11th of August 2019, in the early afternoon, one of the six rack & pinion trains in service suffered a derailment at the Planards point (about three-quarters of the distance down the return trip) during the return trip from Montenvers to Chamonix.

The derailment of the train which takes tourist daily to the Mer de Glace has caused a big fright to the customers, but fortunately, no one was injured.

Yesterday, the 12th of August, a specially commissioned crane has put the locomotive back on the rails, after which the locomotive has been brought down to the depot in Chamonix for a closer inspection.

The track has suffered minor damage in the zone where the derailment occurred. The track teams are at the present moment repairing the damaged sections.

Consequently, the access to the Montenvers - Mer de Glace will be closed today, the 13th of August 2019, to permit these repairs to be completed.

The Compagnie du Mont-Blanc apologizes to the 150 customers who were seated in the derailed locomotive, but also to all the clients at Montenvers last Sunday.

The CMB will hold a new press release as soon as possible, to provide information regarding the track repair & the planned resuming of normal service.
