The Bernina Express and the ordinary red regional train run the same rails, over the same pass, past the same glaciers. One costs a compulsory reservation and cannot stop where you want. The other is free with your pass and can. Here is the honest comparison — including the one station that settles the argument for most travellers.
The short answer
Bernina Express vs regional train, side by side
| Track and scenery | Identical — there is no separate Express line |
| Cost with a Swiss Travel Pass | Express: reservation of about CHF 32–36. Regional: nothing extra |
| Reservation | Compulsory on the Express, impossible on the regional |
| Windows | Express: sealed panoramic glass curving into the roof. Regional: ordinary windows, many of which open |
| Frequency | Express: one or two a day. Regional: roughly hourly |
| Stopping | Express: through service only. Regional: stops everywhere, including Diavolezza |
| Journey time | Within about 20 minutes of each other |
| Commentary | Express only |
The station that decides it: Diavolezza
This is the argument most comparisons miss entirely. Diavolezza is a request stop on the Bernina line served by regional trains, and the Bernina Express does not stop there.
From the platform a cable car climbs to just under 3,000 m, onto a terrace facing Piz Palü and Piz Bernina across the Pers and Morteratsch glaciers. It is the closest most travellers will ever stand to a major Alpine glacier without walking on ice, and it is the best two hours available anywhere on this line.
If seeing the glaciers up close matters at all, the decision is already made: take the regional train, get off at Diavolezza, ride up, and continue on a later train with the same pass. Booking the Express means watching that cable car go past the window.
Choose by what kind of day you want
The Bernina Express suits you if…
You want one seat for the whole journey and no decisions. The panoramic glass, the guaranteed place and the commentary make it the easy option with older parents, small children, or a connection to protect at the far end.
It is also the safer choice in peak August, when regional trains between Tirano and Poschiavo can genuinely fill up.
The regional train suits you if…
You want to photograph, or to get out. Openable windows beat panoramic glass every time — no reflections, no curved distortion — and the trains run hourly, so a missed connection costs you sixty minutes rather than a day.
It is also the only way to reach Diavolezza, Alp Grüm for lunch, or a couple of hours in Poschiavo.
Reaching St. Moritz either way
From the south
Tirano to St. Moritz
Roughly two and a half hours over the Bernina Pass, climbing about 1,800 m. Regional trains leave about once an hour and need no reservation; the Express runs this as its headline stretch. Coming up from Lake Como, this is the natural way into the Engadin.
From the north
Chur to St. Moritz
About two hours on the Albula line, past the Landwasser Viaduct and through the spiral tunnels. Regional trains cover it hourly with no supplement. Worth knowing: the Bernina Express and the Glacier Express both use this same stretch, so you may already be seeing it on another day of your trip.
What the reservation actually buys
Roughly CHF 32 outside summer and around CHF 36 from May to October, per person, per direction, on top of a pass that already covers the travel. For a family of four riding one way, that is close to CHF 150 for panoramic glass and a guaranteed seat on a route where the regional train is rarely full outside August.
Put the other way round: the reservation is good value if the comfort genuinely changes your day, and poor value if you were going to spend the ride standing at the window with a camera anyway.
What we would actually book
- First trip, want the signature experience: Express one way, regional back. One reservation, both experiences, and the freedom to stop on the return leg.
- Photography is the point: regional both ways, budget for Diavolezza, break at Alp Grüm.
- Travelling with young children or limited mobility: Express. The guaranteed seat and level boarding are worth the fee.
- Peak August, no fixed plan: Express southbound for certainty, regional northbound.
Before you decide
Read the full route breakdown in our complete guide to the Bernina Express — it covers what appears in which hour, so you know what you would be giving up by not stopping. Both trains are part of the Grand Train Tour of Switzerland, and your pass covers a great deal more than the trains: see boats, buses and mountain discounts before you spend on extras.
Changing hotels between St. Moritz and your next stop? A luggage transfer is the difference between hopping off at Diavolezza and standing guard over four suitcases.
When to skip the route altogether
Both options assume this journey belongs in your trip. For a lot of itineraries it does not.
- It is a long detour unless the Engadin is already on your plan. Coming from the Jungfrau region or Zermatt purely to ride this line costs you two travel days on top of the journey itself.
- The best stretch is a fraction of the run. The dramatic climbing section is concentrated, not spread across the whole timetable. Riding a shorter segment of the same track gets you the part people remember without committing the entire day.
If the Engadin is where you are going anyway, the question in this guide is the right one to be asking. If it is not, the honest answer is that a different scenic route will cost you less and give you more.
Bernina Express or regular train — common questions
Can I get off at Diavolezza on the Bernina Express?
No. The Bernina Express runs as a through service and does not stop at Diavolezza. Only the regional trains call there, which is the main reason to choose them if the glacier cable car is on your list.
Do regional trains to St. Moritz need a reservation?
No. The red regional trains over the Bernina Pass and along the Albula line are unreserved and free with a Swiss Travel Pass. You can simply board whichever departure suits you.
Do the regional trains have the same views as the Bernina Express?
Yes — identical, because it is the same track. The Express adds panoramic windows that curve into the roof and audio commentary. The regional train has ordinary windows, many of which open, which most photographers prefer.
How much does the Bernina Express reservation cost?
About CHF 32 in the quieter months and around CHF 36 from May to October, per person and per direction. That is on top of a Swiss Travel Pass, which already covers the travel itself.
Is the regional train much slower to St. Moritz?
Not meaningfully. Tirano to St. Moritz takes roughly two and a half hours either way, and the two are usually within about twenty minutes of each other. The regional train runs roughly hourly, so it is often the faster option in practice.
Which is better for families?
It depends on the children. The Express guarantees everyone a seat together for the whole run, which matters with under-fives. Older children usually get far more out of the regional train, because you can break the journey at Diavolezza or Alp Grüm rather than sitting still for hours.
