In the heart of Valais, Switzerland’s sunniest canton, the city of Sion unfolds between hills crowned by medieval castles and a valley crossed by the Rhône. With a population of around 35,000, according to GeoNames data, Sion is the administrative capital of the region and an essential transport hub. Its railway station, operated by the Swiss Federal Railways (SBB/CFF/FFS), is not a mere stop: it is the point where the rhythms of a community converge, a community that relies on the train to work, study, shop, or access specialised medical services.
For the traveller, Sion station is the gateway to a territory of contrasts: terraced vineyards, hiking trails, ski resorts, and a historical heritage dating back to Roman times. This report examines how this railway node operates, what makes it relevant in the Swiss context, and why it remains a key infrastructure for the territorial cohesion of Valais.
A crossroads in the upper Valais
Sion lies at the confluence of two rivers, the Rhône and the Sionne, and its railway station occupies a strategic position on the line linking Geneva to Brig, passing through Lausanne, Montreux, and Martigny. This route, known as the Rhône line, is one of the country’s main railway arteries and connects southwestern Switzerland with northern Italy via the Simplon Tunnel.
Sion station is also the starting point for the line ascending to the ski resorts of Crans-Montana and other side valleys. Although not all connections are direct, the network of postal buses and regional links complements the rail offer to reach the most remote villages.
Sion’s location, at about 500 metres above sea level, allows the city to enjoy a milder climate than other Alpine areas, which has historically favoured human settlement and, in the modern era, the development of a diversified economy combining agriculture, tourism, and services.
History of a line that transformed the valley
The arrival of the railway in Sion occurred in the second half of the 19th century, in the context of the construction of the Rhône line. The rail connection brought profound change to Valais, a region that until then depended on mountain roads and river transport. The train enabled the export of local products, such as wine and fruit, and facilitated access to the markets of Geneva, Lausanne, and Zurich.
Throughout the 20th century, Sion station was expanded and modernised. The electrification of the line, completed in the early decades of the century, improved train frequency and capacity. After the Second World War, increased passenger and freight traffic led to the construction of new facilities and the integration of the station into the urban transport system.
Sion station does not merely connect points on a map: it has witnessed generations of Valaisans who have found in the train a way to maintain their roots without renouncing the opportunities of the rest of the country.
In recent decades, the station has undergone reforms to improve accessibility and services. The creation of a mobility centre integrating train, bus, and bicycle is an example of how Swiss authorities approach public transport planning.
The station today: services and accessibility
Sion station has facilities designed for both daily travellers and tourists. Services include ticket counters, ticket vending machines, a tourist information office, and shops. The station is adapted for people with reduced mobility, with lifts and ramps facilitating access to the platforms.
The main building, with functional architecture, houses a waiting room and several dining options. On the platforms, information panels display real-time departures and arrivals. The station has bicycle parking and a car rental service, allowing train travel to be combined with other forms of mobility.
For residents, the station is a meeting point and a mandatory stop for many daily commutes. Regional trains connect Sion with nearby towns such as Martigny, Sierre, and Brig, while long-distance trains reach Geneva, Zurich, Milan, or Paris with transfers.
The landscape seen from the window
The railway journey through Valais offers some of Switzerland’s most spectacular views. Leaving Sion towards Brig, the train enters a landscape of terraced vineyards, villages with church bell towers, and mountains exceeding 4,000 metres. In spring, almond and cherry trees blossom, while in autumn the vineyards turn red and gold.
The journey towards Geneva, by contrast, skirts Lake Geneva and offers panoramas of the Alps and the lake. The line passes through Montreux, known for its jazz festival, and Lausanne, with its Gothic cathedral and historic old town.
For photography enthusiasts, the section between Sion and Sierre is particularly recommended, as it allows capturing images of the castles of Valère and Tourbillon, which dominate the city from their hills. These castles, along with the Basilica of Valère, are among the region’s most visited monuments.
Everyday usefulness for residents and travellers
For residents of Sion and nearby villages, the railway station is much more than a transit point. It is the primary means of transport for those working in Geneva or Lausanne who have chosen to live in Valais, attracted by the quality of life and more affordable housing prices.
