Stadler and MGBahn present new braking system for cogwheel trains

(CONNECT) In an innovative collaboration, Stadler Rail AG and MGBahn have developed a new braking system for cogwheel trains. The v+ rack-and-pinion braking system went into operation for the first time on a Stadler ORION multiple-unit train on the Andermatt - Göschenen line in the canton of Uri, as the global manufacturer of railway rolling stock from Bussnang reported in a media release. As a result, the “world's fastest rack-and-pinion railway” will reportedly go through the Schöllenen Gorge in future.

The new system allows trains to travel downhill on the line featuring a gradient of 18 percent at speeds of up to 30 km/h. Until now, units were limited to downhill speeds of 21 km/h. “This innovative system enables shorter journey times, more efficient intervals and consequently, more stable timetables,” said Christoph Leiterer,  Head of Engineering for the area Tailor Made at Stadler, in the press release. “From now on, other rack railways can also benefit from and use the new innovative braking system for new purchases.”

MGBahn will retrofit its existing fleet of 11 ORION multiple-unit trains with this advanced braking system. It has also decided to directly install the v+ technology into the 25 new ORION multiple-unit trains, set for delivery starting in 2026. The innovative project has realized the ambition and associated goals of MGBahn, explained Ivan Pfammatter, Head of Rolling Stock & Traction at MGBahn. “We will be travelling faster in the future, guests will benefit from faster and more stable connections and the new technology will enable us to make noticeable operational upgrades.” ce/hs
