Stadler has secured a contract to supply four additional POLARIS cogwheel trains to the Gornergrat Bahn (GGB), further extending a long-standing partnership between the two companies.

The new trains will operate on the route from Zermatt to the Gornergrat, a line famous for its views of the Matterhorn (4,478m) and the surrounding Valais Alps as it climbs to the Gornergrat station (3,089 m elevation).

Valued at approximately 30 million Swiss francs, the order follows previous purchases of five rack-and-pinion trains in 2019 and an additional vehicle in 2024. The latest agreement continues Gornergrat Bahn’s fleet modernisation programme, replacing older rolling stock with vehicles designed specifically for high-alpine conditions.

Engineered to handle gradients of up to 200%, the POLARIS trains are equipped with powerful rack-and-pinion drives. They also feature low-floor access and full accessibility, alongside bright, open interiors intended to enhance passenger comfort.

Large panoramic windows are designed to maximise views along one of Europe’s most renowned mountain routes.

The trains’ interior and exterior styling have been developed by Italian design studio Pininfarina. Manufacturing will take place at Stadler’s plant in Bussnang.

While delivery of the four new units is scheduled for autumn 2028, they are expected to enter regular service from winter 2028, further defining the travel experience on the Gornergrat line.

“The POLARIS multiple units are optimally designed for the conditions of the Gornergrat line and, thanks to modern technology and high performance, increase our operational flexibility.”

Ivan Pfammatter, Head of Rolling Stock at Matterhorn Gotthard Bahn.

“The Gornergrat Railway operates one of the most spectacular and famous railway lines in the
world. We are proud that our trains travel through this unique Alpine landscape every day, offering
passengers an unforgettable experience. This repeat order is a strong sign of confidence in our
rolling stock and our expertise in the field of rack-and-pinion railways.”
