Overview
The S4 does not try to be spectacular, and that is exactly its appeal. It runs the short line between Bludenz and Schruns, cutting through the Montafon valley in Vorarlberg, and it does the job of a proper local train: reliable, unfussy, and quietly scenic without ever making a fuss about it.
This is not a train you plan a holiday around, but it is one that makes a holiday in this corner of Austria much easier. Bludenz sits on the main line, so the S4 becomes the natural link between the wider rail network and the Montafon valley, a region better known for its mountains than its railways.
Anyone expecting a dramatic panoramic showpiece should adjust their expectations. What the S4 offers instead is an honest, valley-hugging ride with real Alpine scenery on both sides, run by ÖBB-Personenverkehr AG as part of the Verkehrsverbund Vorarlberg network, and that is more than enough to justify the trip.

The route: Bludenz to Schruns
The S4 links Bludenz, a town on Austria's main rail arteries, with Schruns, deeper into the Montafon valley. The line effectively acts as the valley's spine, following the natural course carved between the surrounding mountains rather than cutting across them.
The character of the journey is defined by that valley setting: steep wooded slopes, open pasture, and the sense of the terrain gradually closing in as the train moves away from Bludenz towards Schruns. It is a short, focused journey rather than a sprawling cross-country one, and it feels like a direct plunge into Alpine surroundings rather than a gradual build-up.
Timetable and how to book
Services on the S4 vary according to season, reflecting the changing demands of the Montafon valley — busier in winter with the ski trade, and shifting again in summer for walkers and cyclists. Because of this, there is no fixed pattern that holds true all year.
Rather than relying on guesswork or outdated timetables, travellers should check current departures and book, where relevant, directly with ÖBB-Personenverkehr AG. This applies equally to visitors planning a single day trip and to those building a longer itinerary around the Montafon valley.
Fares and classes
As with timetables, exact fares should always be confirmed with ÖBB-Personenverkehr AG rather than assumed, since pricing structures and any regional or seasonal passes are best checked at the point of booking.
In terms of onboard classes, the general distinction on services like this is one of comfort and space rather than any dramatic difference in experience. A higher class of travel typically means a quieter, more spacious carriage with a bit more room to stretch out, while a standard class focuses on straightforward, practical travel for what is, after all, a short valley run. Neither class should be expected to transform the journey — the scenery outside the window is the real draw, not the seat category.
Which side to sit for the best views
Because the S4 travels through a valley rather than along an open plain, the views shift constantly from one side of the train to the other as the line follows the contours of the landscape. There is no single 'best' side that holds for the whole trip; instead, travellers benefit from staying alert and looking both ways as the train moves between Bludenz and Schruns.
For the fullest impression of the Montafon valley's scale, it helps to sit where you have an unobstructed view rather than fixating on a particular side. Those travelling for the scenery rather than for speed should treat the journey as one to be watched throughout, rather than settle in and assume the view will stay the same for the whole ride.
Onboard experience
As a regional service in the ÖBB network, the S4 is built around practicality: comfortable seating, windows that let the surrounding landscape do the work, and a straightforward, no-nonsense approach to getting passengers along the valley. This is not a train dressed up as a tourist attraction, and it is better for it — the landscape provides the drama, not the carriage.
Passengers should not expect an elaborate onboard experience in the way of a long-distance or international service. It is a train designed for a valley community as much as for visitors, and that everyday character is part of its charm.
Best time of year to ride
The Montafon valley changes considerably across the year, and the S4 becomes a different kind of journey depending on when you take it. Winter brings snow-covered slopes and a clear sense of arriving in ski country, with the valley's mountain backdrop turned properly Alpine.
Summer offers greener slopes, longer daylight for taking in the scenery, and a more relaxed pace suited to walkers and cyclists using Schruns as a base. Spring and autumn sit between the two, often quieter, with the valley's transitional colours and lighter passenger loads offering their own appeal for travellers who prefer to avoid peak season.
Alternatives and onward connections
At Bludenz, the S4 connects into Austria's wider main-line network, making it a natural link for travellers arriving from elsewhere in the country or beyond who want to continue into the Montafon valley without switching to road transport.
At Schruns, the train reaches the effective heart of the valley, from where onward travel typically shifts to local buses or other regional transport for those heading further into the surrounding mountains and villages. Travellers should treat Schruns as a hub for the next stage of the journey rather than a final full stop, particularly if their destination lies beyond the town itself.
History and context
The S4 belongs to a long tradition of valley railways built to connect Alpine communities to the main national network, at a time when a rail link was the difference between isolation and integration for towns like Schruns.
Today, run under ÖBB-Personenverkehr AG and organised within the Verkehrsverbund Vorarlberg regional network, the line continues that original purpose in a modern form — less about opening up the valley for the first time, and more about keeping it conveniently connected for residents and visitors alike.
Common questions
- Do I need to book the S4 in advance?
- This depends on the season and current operator policy. Always check with ÖBB-Personenverkehr AG for up-to-date timetable and booking information before travelling.
- Is the S4 a scenic tourist train?
- No — it is a regional service designed for practical travel through the Montafon valley. The scenery is genuinely good, but the train itself is built for everyday use rather than as a dedicated sightseeing experience.
- Which side of the train has the best views?
- There is no single best side throughout the journey, as the valley setting means views shift from one side to the other. It is worth staying alert and looking both ways rather than settling on one side for the whole trip.
- What is at Schruns once I arrive?
- Schruns acts as a hub for the Montafon valley, with onward local transport typically available for travellers continuing further into the surrounding area.
- Does the experience change with the seasons?
- Yes. Winter brings a snow-covered, ski-focused atmosphere, while summer suits walkers and cyclists with greener scenery and longer days. Spring and autumn tend to be quieter, transitional periods.
