Overview
The S31 is a regional rail service operated by SOB that connects Arth-Goldau with Biberbrugg, threading through the Schwyz region of central Switzerland. This is a working local train, not a tourist spectacular—it moves commuters, shoppers and day-trippers through genuinely varied terrain, from lakeside to forest to rolling farmland. If you're travelling this route, you'll experience the understated efficiency of Swiss rail at its most practical.
The journey demands respect for the timetable but rewards those who choose the right seat and the right time of day. This is not a line of dramatic Alpine passes or thunderous mountain climbs; instead, it's a portrait of how Switzerland moves people through a quiet, prosperous landscape, served by frequent local trains that fit seamlessly into regional life.

The route: Arth-Goldau to Biberbrugg
Arth-Goldau sits at the northern foot of the Rigi massif, a transport hub where the S31 begins its transit across the Schwyz region. From here, the line does not climb; instead it moves eastward and northward through landscape that transitions from lakeside meadow to woodland to mixed agricultural terrain. The journey is fundamentally about connection rather than spectacle—linking smaller towns and villages that form the everyday sinews of central Switzerland.
The S31 passes through the characteristic landscape of the Schwyz lowlands: neat farms with traditional chalets, small forests of mixed deciduous and evergreen trees, and periodic views across pastoral valleys. The terrain is rolling rather than mountainous, with the Alps visible on the horizon on clear days but never dominating the immediate view. This is Switzerland as lived space, not postcard Switzerland.
The arrival at Biberbrugg marks the northern extent of the service, a modest but properly served station at the edge of the Sihl valley. The whole journey occupies a relatively short distance but passes through enough variation in settlement and landscape to feel like a genuine regional traverse rather than a commuter shuttle.
Timetables and booking
The S31 operates on a regular local service pattern, with frequency that varies between weekday and weekend schedules. Services also shift seasonally—summer and winter timetables differ materially in their frequency and timing. You must consult SOB directly (the operator) for current departure times, as these change regularly and any published time would become obsolete.
Booking is straightforward: tickets can be purchased at station machines, from staffed counters, or online through SOB's ticketing system. For regular travellers, seasonal passes and subscriptions offer better value than single journeys. Day-trip planning requires checking the forward timetable first; do not assume even frequency.
Fares and travelling conditions
The S31 is a regional train, not an express service, so expectations should align accordingly. Standard-class accommodation is practical and comfortable: seats are designed for the typical local journey length, with good sightlines out of the windows. First-class carriages, where available, offer wider seats and a quieter environment, plus the psychological benefit of fewer fellow passengers during peak times.
Neither class includes catering, though the journey length is short enough that this is rarely an issue. First-class passengers may find the marginally superior comfort worthwhile if travelling during rush hours or if you value a more tranquil environment. For the casual day-tripper, standard class is perfectly adequate and the norm.
Fares are determined by distance travelled within the Tarifverbund Schwyz zone system. Specific prices must be checked with SOB—they vary by passenger type, ticket validity, and the type of ticket purchased, whether a single journey or longer-term pass. Family discounts and group rates may apply; verify with the operator.
Where to sit for the best journey
The S31's route runs broadly northward from Arth-Goldau, so there is no single 'correct' side of the train for views. Instead, consider the lighting: morning light from the east will illuminate the right-hand side of the train; afternoon light from the west will favour the left. Clear days offer distant Alpine views that appear across both sides at different points.
The most rewarding seats are those forward-facing in the direction of travel, where the landscape unfolds ahead rather than sliding past sideways. Standard-class windows are large enough to provide good sightlines; avoid seats directly over the wheels if sensitivity to vibration is a concern. First-class seating is more spacious and sits higher, offering marginally better forward vision.
Avoid travelling during rush hours if you want to secure a window seat or any significant personal space. Early morning and mid-afternoon services tend to be quieter. The landscape changes subtly throughout the journey, so moving between cars to follow the most interesting views is entirely reasonable on a train this length.
The travelling experience
An S31 journey is unpretentious and efficient. The train announces stops clearly; many passengers board and alight at each station. This is not a line where you sit in isolation; it's a working part of the regional transport network, carrying schoolchildren, commuters, and locals running errands. The atmosphere is orderly and quiet, with passengers respecting the standard Swiss railway convention that conversation should be kept moderate.
Panoramic windows are standard, offering continuous views without the obstruction of heavy glazing bars. Air conditioning is present in modern rolling stock. Toilets are available on board, as on all reasonably sized Swiss regional services. The train itself is neither luxurious nor cramped—it's built to the pragmatic standard of Swiss regional rail: clean, well-maintained, reliable, and fit for purpose.
Journey time from Arth-Goldau to Biberbrugg is moderate—long enough to settle in and watch the landscape, but short enough that you'll arrive before the novelty of travel has worn off. This is not a sleeper service or a long-haul expedition; it's a straightforward regional commute that happens to pass through attractive terrain.
The best season to travel
Spring (March to May) brings fresh growth to the farmland and woodlands along the route, with the Rigi and more distant peaks still snow-capped on clear days. The light is bright and shadow-free for much of the morning. Vegetation is emerging but not yet so dense as to block views.
Summer (June to August) deepens the greens and brings the longest daylight hours, making evening journeys particularly pleasant. Heat can make carriages uncomfortable on very warm afternoons if the train is crowded, though modern stock handles this better than older trains. The Alps are clearer on settled days.
Autumn (September to November) provides sharp light, fewer crowds than summer, and the gradual shift from green to gold in the deciduous woodlands. This is perhaps the most comfortable season for travelling, with moderate temperatures and excellent visibility.
Winter (December to February) brings the possibility of snow on higher elevations visible from the route, and on rare occasions, snow at valley level. Daylight is shorter, limiting afternoon sightseeing. Clear winter days offer spectacular Alpine views, but cloudy conditions—common in central Switzerland at this season—reduce visibility significantly. Services are reliable regardless of weather, as Swiss rail maintains stringent standards.
Onward travel from Biberbrugg
Biberbrugg is a properly connected regional station, with onward rail services linking into the broader Swiss network. From here, travellers can continue northward into the Zurich region, or access other regional services within the Schwyz tariff zone. The station is modest but adequately staffed and equipped with typical amenities.
Bus connections are also available for those wishing to explore the surrounding valleys and smaller settlements not served by rail. Bicycle facilities are standard at Swiss regional stations, allowing for multi-modal journey planning. Check SOB's journey planner for current onward connections before travelling, as these vary seasonally and by time of day.
Context: the S31 in regional Swiss rail
The S31 operates as part of SOB's broader regional rail network in the Schwyz region, itself part of the integrated Swiss public transport system. The infrastructure supporting this service—the track, signalling, and operating standards—reflects Switzerland's long railway heritage and its commitment to frequent, reliable local rail services as essential to regional mobility.
This is a line without romantic history or Alpine glamour; it exists because the terrain it crosses, the settlements it links, and the passengers it serves warrant efficient rail connection. In that quiet utility lies its genuine value. The S31 is neither a heritage service nor a high-speed express—it is what functional regional rail looks like when it works properly.
Common questions
- How do I check the current timetable?
- Contact SOB directly or consult their online timetable service. Services vary by season and day of the week, and times change regularly. Station displays and printed timetables at Arth-Goldau and Biberbrugg are also reliable sources of current information.
- Is this train suitable for someone carrying luggage or a bicycle?
- Yes. Swiss regional trains accommodate luggage in designated spaces and have secure bicycle racks or storage. Verify luggage policies and bicycle booking requirements with SOB if you're carrying non-standard items, but standard day-trip luggage presents no problem.
- What is the difference between standard and first class on the S31?
- First class offers wider, more comfortable seating and a quieter atmosphere, typically preferred during busy commuter periods. Standard class is perfectly adequate for most journeys and is the norm for regional travel in this region. Facilities such as toilets and windows are available in both classes. Consult SOB for current pricing differences.
- Can I break my journey at intermediate stations?
- Yes, absolutely. The S31 stops at multiple stations between Arth-Goldau and Biberbrugg. A single ticket typically allows you to travel at a relaxed pace, alighting wherever interests you, provided you do so before reaching your final destination. Confirm ticket validity with SOB for any specific journey plan.
- Is this a scenic train, or a working commuter service?
- It is a working commuter and regional service that happens to pass through pleasant landscape. It is not a specialised tourist train with commentary or premium catering. The scenery is genuine and rewarding, but modest compared to Alpine express services. It's a journey of quiet interest rather than dramatic spectacle.
