Switzerland by panoramic train: Alps, lakes and punctuality

I have a soft spot for trains that keep their promises, and Switzerland is where that obsession finally felt normal. Here, when the board says 9:42, the train pulls out at 9:42 — not 9:43 — and the connection three minutes later on the far platform actually waits for you. After years of apologising for European railways, I spent a week being quietly, deeply spoiled.

The plan was simple on paper: cross the Alps the slow way, by panoramic train, and let the mountains do the talking. The Glacier Express from the Valais toward the Grisons, the Bernina line climbing toward Italy past glaciers and palm trees in the same afternoon. Eight hours to cover what a car would rush in four. That gap is the whole point.

The Glacier Express, the slowest fast train

They call it the slowest express in the world, and they say it with pride. Panoramic windows that curve up into the roof, a valley unrolling on both sides, viaducts you cross while craning your neck to see the river far below. I'd booked a window seat days ahead — do the same, the good side fills up — and I barely touched my phone for the first hour. Then I reached for it anyway, because a glacier framed in a curved window is the kind of thing you want to send to someone immediately.

« In Switzerland the train is on time, the view is unfair, and the only thing that wavers is the signal in the tunnels. »

Here's the honest part, and it matters more in Switzerland than almost anywhere else in Europe: Switzerland is not in the EU or the EEA. That sounds like trivia until your phone bill arrives. The European « roam-like-at-home » that makes your plan work seamlessly in France, Italy or Germany generally does not cover Switzerland — many travellers get stung with out-of-bundle roaming charges the moment they cross the border, sometimes without realising it. It's a genuine trap, and it's exactly why an eSIM earns its keep here. I had mine running before I left the platform in Zermatt, and the bill that scared people at my guesthouse never came for me.

Coverage that's excellent — until the mountain says no

Let me be fair to Switzerland: the network is, broadly, superb. In the cities, along the lakes, in most valleys, you get fast, stable data and you stop thinking about it. The catch is geography. These trains spend a lot of time inside the mountain — long tunnels where the signal simply drops, deep valleys boxed in by rock where it thins to nothing for a few minutes. It always came back; I'd just learned not to start a video call right as we entered a portal.

So I did what I always do and front-loaded the offline stuff: the route map downloaded, my tickets saved as screenshots and in the railway app's offline mode, a playlist for the dark stretches. The eSIM was there for the moments that count — checking the Bernina connection at Chur, sending my parents a photo from Lake Brienz so absurdly turquoise they assumed I'd edited it, pulling up the next departure when a plan changed.

Lakes below, summits above

Between the big panoramic lines, Switzerland is a country you assemble out of small perfect rides. A lake steamer on Lac Léman with the Alps stacked on the horizon. The climb to a mountain station where you step off into thin, bright air and the whole range opens up. I kept a loose thread going with people back home all week — a photo here, a one-line message there — not because I needed to, but because some views feel rude to keep to yourself. With data that worked nearly everywhere, that thread cost me nothing but the seconds to send it.

What I take away

Switzerland is the rare place that lives up to its postcard — the trains really do run to the minute, the lakes really are that colour, and the Alps really do stop you mid-sentence. The only thing that doesn't run smoothly is the border arithmetic on your data plan, and that's a five-minute fix before you leave. Sort it once, then spend the week looking out the window with both hands free.
