The train of the Mont-Blanc valleys
History and engineering of Mont-Blanc Express

After les Égratz: les Gures, and the Servoz plateau

After the Égratz tunnel, the railway enters a narrow canyon, still in a 90 mm/m slope. This place is called les Gures. A power station is located there. It initially powered the railway; now it is operated by EDF and connected to the utility grid. The railway again runs under the elevated expressway.

The canyon ends at the place called le Châtelard, which hosts a roadsite service area. After a short tunnel in le Châtelard, the railway reaches the Servoz plateau.

As the track crosses the Châtelard gorge at the foot of the Égratz viaduct, the Aiguille du Midi appears, still shrouded in mist, but already imposing and majestic. The slope here is 90 mm/m, the steepest on the entire line.
