We got a tour inside the control and machine rooms of the Matterhorn 3S system (Trockener Steg to Klein Matterhorn & Italy border) - here's how it handles 100 km/h winds and winter operations
With winter season coming up, a lot of people planning trips between Zermatt and Cervinia ask about wind holds at the top and how the new 3S lifts actually operate at 3,883m.
We recently got access from Zermatt Bergbahnen to walk through the control rooms, maintenance bays, and underground drive rooms at Trockener Steg and Matterhorn Glacier Paradise with Markus Schwizer from their team. Here are a few cool things we learned that you don't normally see as a skier riding up:
- Unlike standard gondolas on a single loop, the 3S runs on two fixed steel track cables (anchored at 70 tons of tension each) and one haul rope. That stability lets it cross a 3 km gap without a single support tower and keep running in winds up to 100 km/h.
- The old cable car maxed out at around 600 people an hour. The 52M CHF 3S upgrade pushed capacity to 2,000 people an hour, and the stations use angled ramps so gravity naturally slows cabins down from ~30 km/h on arrival and speeds them up on exit.
- The cabins don't have power cables attached while moving on the line. Instead, overhead rails in the station push a massive charge into supercapacitors in just a few seconds to run cabin electronics and cameras. The heated Pininfarina seats follow a strict safety protocol and only draw power while passing through the station.
- Everything is built with double or triple redundancy, two separate IT networks, fiber-optic lines inside the core of the steel track cables, gearless direct drives, emergency generators, and a diesel-hydraulic backup. Even if an entire underground technical room catches fire or the grid goes down, the system can bring every cabin back to the station on its own.
If you want to see what the machine rooms, the 70-ton cable bollards, and the cantilevered foundation hanging off the cliff at 3,883m look like from the inside, here's the full 21-minute video we filmed up there: https://www.youtube.com/watch?v=rZdrrefv68E
