Chemin de fer du Montenvers, Heritage railway in Chamonix-Mont-Blanc, France.
The Montenvers Railway connects Chamonix with a mountain station at high altitude, climbing over 1,000 meters through steep Alpine slopes. The rack-and-pinion system allows trains to navigate gradients exceeding 20 percent and bring visitors near the Mer de Glace glacier.
The railway began service in 1909 using steam locomotives, before switching to electric power in 1953. This change allowed for more efficient and frequent trips up the mountain.
The station houses the Glaciorium, an educational center focusing on glacier studies, climate research, and environmental preservation in the Alpine region.
The journey lasts about 20 minutes and the train moves slowly so passengers can enjoy the views. Bring warm clothing since it is noticeably colder at the top than in the valley below.
The railway uses a special gear system that allows it to climb mountain slopes that would otherwise be impossible to traverse. This technical feature makes the route one of the steepest of its kind in the Alps.
