Mont Blanc Express

Mont Blanc Express. A historic meter-gauge railway operating in the Alps, connecting France and Switzerland through the Chamonix Valley and the Trient Valley. Operated jointly by the Compagnie du Mont-Blanc and Transports de Martigny et Régions, it is renowned as a scenic railway offering dramatic views of the Mont Blanc massif, Glacier des Bossons, and the Mer de Glace.

History

The railway's development was driven by the growth of alpinism and tourism in the late 19th century, particularly following the inaugural ascent of Mont Blanc. The first section from Saint-Gervais-les-Bains to Le Fayet opened, later extending towards Chamonix under the direction of the Compagnie des Chemins de Fer de Paris à Lyon et à la Méditerranée. The challenging international link to Martigny was completed, involving significant engineering like the Tunnel du Châtelard and cooperation with the Swiss Federal Railways. Key figures in its promotion included local industrialists and officials from the Department of Haute-Savoie.

Route and stations

The line traverses approximately 55 kilometers of mountainous terrain, beginning at the mainline connection in Saint-Gervais-les-Bains. It climbs the Vallée de l'Arve, serving iconic resorts like Les Houches and the alpine hub of Chamonix-Mont-Blanc. Notable engineering features include the Viaduc de la Tête Noire and the steep gradients negotiated by the rack railway system near Le Châtelard. After crossing the border at Le Châtelard-Frontière, it descends through the Trient Valley past the Salvan region before terminating at the Rhône valley station in Martigny, connecting to services for Sion and Brig, Switzerland.

Rolling stock

The fleet primarily consists of distinctive red electric multiple units. For the steep rack sections, powerful Bhe 4/8 and Bhe 4/10 class locomotives, built by SLM Winterthur with electrical equipment from BBC Brown Boveri, are employed. Modernization has introduced newer stock like the ABDeh 8/8 series. The railway's characteristic livery and design are a familiar sight, contrasting with the green landscapes of the Aiguilles Rouges and the white peaks of the Grandes Jorasses.

Operations

Operations are split at the national border, with the Compagnie du Mont-Blanc managing the French segment and Transports de Martigny et Régions the Swiss portion. The line utilizes a mix of adhesion railway and rack railway technology to overcome gradients. It provides vital regional transport, connecting to the Montenvers Railway for the Mer de Glace and interfacing with TER Auvergne-Rhône-Alpes and SBB-CFF-FFS networks. Seasonal services increase during the winter for skiers heading to Les Planards and summer for hikers exploring the Tour du Mont Blanc.

Tourism and cultural significance

The railway is a major tourist attraction, integral to the identity of the Chamonix Valley and a key component of the Mont Blanc region. It provides access to legendary sites like the Aiguille du Midi cable car and the Glacier du Trient. The journey is celebrated in travel literature and photography, emblematic of alpine exploration. It features in cultural events and supports ecotourism by offering an alternative to road travel through the sensitive ecosystems of the Alps, within sight of peaks like the Dôme du Goûter and the Aiguille Verte.
