The most significant "new" scenic train in Switzerland is the GoldenPass Express, which launched its full direct service between Montreux and Interlaken in late 2022 and has become a major highlight for 2025–2026 travelers. What makes this train revolutionary is its "gauge-changing" technology; previously, passengers had to change trains in Zweisimmen because the tracks changed from standard to narrow gauge. The GoldenPass Express features specialized bogies that actually expand or contract their wheels while the train is moving, allowing for a seamless 3-hour and 15-minute journey. The train offers a "Prestige Class" with heated, rotating leather seats that face the window, providing panoramic views of Lake Geneva, the Swiss Riviera, and the Bernese Oberland. It is considered one of the most technologically advanced and luxurious scenic routes in Europe, joining the ranks of the legendary Glacier Express and Bernina Express as a "must-do" rail experience for visitors to the Swiss Alps.
