The Bernina line climbs to 2,253 metres at Ospizio Bernina without a single rack rail or cable — adhesion alone, steel wheel gripping steel track, on gradients of seven percent.
That engineering stubbornness is why UNESCO inscribed the Albula/Bernina route in 2008, one of only three railways on the World Heritage list. A milan to swiss alps train tour follows the southern half of that inscription, beginning where Italian Valtellina ends and Graubünden begins.
The route was completed in 1910 under engineer Friedrich Hennings, who refused tunnelling shortcuts wherever a spiral could hold the grade instead. The Brusio circular viaduct is the result: nine stone arches curving through 360 degrees in open daylight, a solution to elevation that looks like an accident of geometry. The Landwasser Viaduct, further north on the Albula stretch, drives straight into a cliff face. Both are load-bearing masonry, still carrying scheduled service more than a century after the last block was laid.
What makes the line matter now is less nostalgia than function. This is a working metre-gauge railway operated by the Rhaetian Railway, not a heritage attraction. Freight moves on it. Villages along the Val Poschiavo — Miralago, Cavaglia, Alp Grüm — depend on it in February as much as August. The panoramic carriages with their curved observation glass are simply the tourist expression of infrastructure that exists regardless of visitors. Passengers on a milan to swiss alps train tour tour share the corridor with commuters carrying groceries.
The geography compresses unusually fast. In roughly two hours the train passes from chestnut and vine terraces near Tirano to the Morteratsch Glacier's terminal moraine, a transition that would take a full day on foot. Palm-adjacent Mediterranean flora gives way to larch, then to bare rock and the Lago Bianco reservoir, its water milk-white with glacial rock flour. The climatic band crossed is closer to what a traveller would cover between Lombardy and Lapland.
St. Moritz at the northern end has been a resort since 1864, when hotelier Johannes Badrutt wagered English summer guests that they would find the winter sun agreeable — and won. The Rhaetian Railway's own base sits at Bahnhofstrasse 25, 7001 Chur, Switzerland. Tirano at the southern end remains a small Italian border town with a pilgrimage basilica and a level crossing where the train runs down the middle of the street. Most bernina express day tour operators from Milan connect the two, and milan to swiss alps train tour tickets for the rail leg start from a base 2nd class one-way fare of 33 CHF between Tirano and St. Moritz.
