Spiraling around the open-air stone masonry of the Brusio Circular Viaduct as a red Swiss mountain train drops from high-altitude glacier peaks into the sun-drenched palm trees of northern Italy is one of the greatest rail spectacles on Earth—and you can experience every single kilometer without paying the hefty tourist seat reservation fees of the official Bernina Express.

While the official Bernina Express charges mandatory seat reservation supplements of CHF 26 to CHF 36 per person (with zero flexibility to change seats or open windows), standard regional trains operated by the Rhätische Bahn (RhB) run along the identical UNESCO World Heritage tracks between Chur, St. Moritz, and Tirano every single hour. For savvy travelers and photographers, regional cars offer a superior experience: drop-down sash windows that open wide for glare-free photography, yellow open-air observation carriages in summer, and total freedom to hop on and off at breathtaking high-altitude stops like Ospizio Bernina and Alp Grüm.

Why You’ll Love Riding the Bernina Line on Regional Trains

• Zero Reservation Surcharges: Skip the mandatory seat fee entirely. The route is 100% covered by the Swiss Travel Pass, Eurail/Interrail Global Pass, and SBB Saver Day Passes with zero out-of-pocket supplement.
• Sliding Windows for Crisp Photography: Unlike the sealed, double-glazed panoramic windows of the tourist train that trap glare and reflections, regional train windows slide open completely for unobstructed landscape photos.
• Spontaneous Alpine Stopovers: Regional trains depart every 60 minutes. Hop off at Alp Grüm (2,091m) to savor lunch overlooking the Palü Glacier, or hike along the milky turquoise waters of Lago Bianco before catching the next train.
• The Historic Open-Air Carriages (Summer): From June to September, select regional departures include legendary open-top yellow wagons (Aussichtswagen) that let you feel the crisp glacier breeze directly on your face.

Bernina Pass Rail Essentials: What to Pack in Your Daypack

• High-Altitude UV Sunglasses: The blinding white granite reflections around Lago Bianco and the Cambrena Glacier at 2,253 meters demand category 3 polarized eye protection.
• Windproof Fleece or Softshell: While train carriages are heated, leaning out of sliding windows or stepping onto the Alp Grüm viewpoint exposes you to brisk alpine drafts.
• Passport or EU National ID: You will cross the international border between Switzerland and Italy at Campocologno/Tirano, where Swiss and Italian border police occasionally board for spot checks.
• Euros & Swiss Francs: Switzerland uses CHF, while Tirano uses the Euro (€). Keep a small amount of cash in both currencies for quick platform espressos and gelato.

Chur / St. Moritz to Tirano: Step-by-Step Regional Rail Breakdown

Leg 1: St. Moritz / Pontresina to the High Bernina Pass

Board the hourly red RhB regional train departing St. Moritz or Pontresina. The train gently climbs past the Morteratsch Glacier, where sweeping views of the Piz Bernina massif (4,049m) dominate the western horizon.

Skirt the pristine, icy shores of Lago Bianco (White Lake), named for its milky glacial runoff, arriving at Ospizio Bernina (2,253 meters / 7,392 feet)—the highest point reached by any railway in Europe without a cogwheel rack.

Leg 2: The Dramatic Descent to Alp Grüm & Poschiavo Valley

Leaving Ospizio Bernina, the train enters a series of horseshoe curves carved into the granite cliffside toward Alp Grüm. Here, the panoramic terrace offers unmatched vistas of the turquoise Palü Glacier and the emerald Val Poschiavo thousands of feet below.

The train snakes through dizzying avalanche galleries and 180-degree loops without cogwheels, dropping over 1,800 vertical meters into the Italian-speaking Swiss valley of Poschiavo.

Leg 3: The Brusio Spiral Viaduct & Italian Arrival in Tirano

Just south of Poschiavo near the village of Brusio, the railway performs its most legendary architectural feat: the Brusio Spiral Viaduct. To lose 20 meters of elevation in an extraordinarily confined valley space, the track loops completely over itself on a graceful 110-meter-radius stone bridge.

Cross the Italian frontier into Tirano. Step off the train directly into the sunlit piazza, where palm trees, terracotta roofs, and authentic Italian trattorias welcome you. Enjoy a plate of local buckwheat pizzoccheri pasta and an espresso before catching the regional train back into the Swiss Alps or continuing south toward Lake Como and Milan.

3 Insider Secrets for Riding the Bernina Route on a Budget

1. Sit on the Right Side Departing St. Moritz / Pontresina: Heading south toward Tirano, sit on the right-hand side of the train for front-row views of the Morteratsch Glacier, Lago Bianco, the sweeping Alp Grüm drop-off, and the outer loop of the Brusio Viaduct.

2. Hop Off at Alp Grüm for an Alpine Lunch: Because regional trains run hourly, disembark at Alp Grüm station. Walk 50 meters to the cliffside restaurant terrace for a bowl of authentic Grisons barley soup while watching the next red train snake across the valley floor below.

3. Seamless Connection to Lake Como: Tirano station directly borders the Italian Trenord rail network. For just €8.40, you can catch an hourly Italian regional train from Tirano along the eastern shore of Lake Como to Varenna-Esino and Milan Centrale.

Where to Base Yourself: St. Moritz vs. Pontresina vs. Tirano

• Pontresina (Classic Alpine Base): Less commercial than St. Moritz, offering charming Engadin sgraffito-decorated chalets, quiet mountain ambiance, and direct hourly Bernina train departures.
• St. Moritz (High-End Glamour): Ideal for travelers seeking luxury boutique shopping, crystalline lakeside promenades, and world-class 5-star hospitality.
• Tirano (Budget Italian Gateway): A fantastic budget-saving overnight base. Hotel rates and dining in Tirano are approximately 60% cheaper than in the Engadin valley, featuring authentic Valtellina wine culture.

• Train Frequency: Regional RhB trains operate consistently once every hour between St. Moritz/Pontresina and Tirano from 06:45 AM until 20:45 PM daily.

Frequently Asked Questions

Do regional trains travel over the Brusio Spiral Viaduct?
Yes, absolutely. Every single passenger train on the Bernina Line—both regional commuter trains and official Bernina Express panoramic trains—crosses the exact same Brusio Viaduct.

Do I need a passport on the Bernina train?
Yes. Because Tirano is located in Lombardy, Italy, you will cross the Swiss-Italian border. Although both nations are within the Schengen Area, identity checks occasionally take place on the platform or train.

Can I open the windows on regional trains?
Yes. Standard RhB regional cars have sliding sash windows that can be pulled down for crystal-clear, reflection-free photography of the glaciers, bridges, and mountain passes.
