Overview
The S26 doesn't try to sell itself as a scenic showpiece, and that's rather the point. This is a working Swiss regional train, part of the A-Welle network, quietly stitching together Rotkreuz and Olten through the sort of unshowy central Swiss and Aargau countryside that rewards a traveller who isn't in a rush.
There's no drama here, no glacier panorama or lakeside cliff-hugging track. What you get instead is a practical, comfortable cross-country link that locals rely on daily and that visitors can use to slot together a longer Swiss itinerary without fuss. It's the kind of train that makes the whole national rail network feel joined-up.
If you want an honest, unglamorous slice of how Switzerland actually moves people around, the S26 is a decent teacher. Read on for how to make the most of it.

The route: Rotkreuz to Olten
Rotkreuz sits in the canton of Zug, a modest but well-connected junction town rather than a tourist draw in itself, and the S26 heads out from there across a landscape of rolling farmland, scattered villages and the low hills typical of this part of central Switzerland. It's a gentle, green, agricultural corridor rather than an alpine one.
As the train continues towards Olten, in the canton of Solothurn, the terrain doesn't change dramatically — this is Switzerland's quieter middle ground, away from the big lakes and high peaks, but pleasant in an understated way. Olten itself is a genuine railway town, a hub where several lines converge, so the journey has a real sense of arriving somewhere that matters to the network even if it isn't famous itself.
Overall the journey feels less like a scenic excursion and more like a useful cross-connection — comfortable, steady, and handy for linking central Switzerland with the northwest of the country.
Timetable and how to book
As with all S-Bahn services in Switzerland, the S26 runs to a regular pattern that can vary by season, day of the week and time of day. Rather than rely on any timing quoted elsewhere, check current departures directly with SBB, either via their website, app or at the station.
Booking in the conventional sense is rarely necessary for a regional train like this — most passengers simply buy or load a ticket and board. If you're travelling with a Swiss Travel Pass, a regional day pass, or a points-based ticket, confirm validity and any seasonal timetable changes with SBB before you travel, especially if you're building the S26 into a tighter connecting itinerary.
Fares and classes
Swiss regional trains typically offer two classes, and the S26 follows that pattern. Second class is the standard, practical option: comfortable upholstered seating, big windows, and perfectly good for a journey of this length. First class, where offered, generally means a quieter carriage, a little more space around you, and a slightly calmer atmosphere — useful if you want to work or simply enjoy the ride with fewer distractions.
Neither class turns this into a luxury experience, and it isn't meant to. The differences are about comfort and space rather than added extras. For exact fares, check SBB directly rather than assuming a price — regional fares are structured by distance and any pass or card you're using, and it's not worth guessing.
Which side to sit for the views
Because the S26 crosses gently undulating farmland and low hills rather than following a dramatic ridge or lakeshore, there isn't a single obviously superior side to sit on for the whole journey. Rather than fixating on left or right, it's worth simply taking a window seat and letting the outlook shift as the train moves between open fields, village edges and wooded rises.
If you have the flexibility, an aisle-facing glance across both sides as the train pulls out of smaller stations often rewards you with a decent view of the surrounding countryside opening up. This is a journey where the pleasure is cumulative and unshowy rather than built around one big reveal.
Onboard experience
Expect the standard, dependable feel of a modern Swiss regional train: clean carriages, large windows that make the most of whatever light and landscape you're passing, and the sort of unfussy comfort that lets you read, work or simply watch the country go by.
Don't expect a dedicated catering trolley or restaurant car — journeys of this length and character on Swiss S-Bahn lines are generally set up for straightforward point-to-point travel rather than an onboard dining experience. If refreshments matter to you, it's sensible to pick something up at Rotkreuz or one of the intermediate stations before boarding.
Best time of year to travel
Spring brings freshly green fields and a certain lift to the whole landscape between Rotkreuz and Olten, while summer offers long daylight hours that make the most of the open countryside views. Autumn turns the farmland and wooded patches into a warmer palette, which suits the unhurried character of this route rather well.
Winter has its own appeal too — a starker, quieter version of the same landscape, with the low hills and villages taking on a more subdued, atmospheric look. There's no single best season here so much as a matter of what mood you want from the journey; the S26 works as a pleasant, functional ride at any time of year.
Alternatives and onward connections
Olten's significance as a Swiss railway hub means that arriving there on the S26 typically opens up a good range of onward connections across the national network, making it a sensible interchange point rather than a dead end. Passengers heading further afield — whether north, south, east or west — will generally find good links from here, though exact services and timings should always be checked with SBB.
If your priority is speed rather than the regional character of the S26, there may be faster main-line alternatives covering parts of the same corridor. But for a straightforward, no-nonsense link between Rotkreuz and Olten, the S26 does the job cleanly and is well integrated into the wider A-Welle network.
A little context
The S26 belongs to the A-Welle network, part of the broader modernisation of Swiss regional rail that has, over successive eras, turned a patchwork of local lines into the tightly coordinated S-Bahn systems the country is known for today. Services like this one exist because of a long-standing Swiss commitment to frequent, reliable regional connections rather than headline express routes.
Rotkreuz and Olten, each a junction of some importance in their own right, reflect that same philosophy: unglamorous but essential nodes that keep the wider network functioning. The S26 is best understood not as a scenic one-off but as a thread in that much larger, patiently built fabric of Swiss rail.
