Eismeer: a five-minute window inside the mountain.
Deep in the tunnel, the train stops and the doors open onto a stone gallery looking straight out over a glacier field — one of only two window stations ever built into this line.
Built as a construction shortcut, kept as a feature.
During construction, engineers needed points along the tunnel route to remove excavated rock and bring in materials without hauling everything back through the single entrance at Eigergletscher. Several of these access galleries were cut straight through the rock face into open air. Two were kept and finished as passenger window stations once the line opened in 1912: Eigerwand, roughly midway up the face, and Eismeer, higher still at 3,158 m, named for the "sea of ice" glacier field visible from its gallery.
Why Eigerwand isn't a stop anymore
Eigerwand's scheduled passenger stop was discontinued in December 2016, when new Stadler Rail train units entered service and cut the Kleine Scheidegg–Jungfraujoch journey time from 52 minutes to 35 — partly achieved by dropping the Eigerwand stop, which also freed up enough schedule time to run one additional train per day. Eismeer, being closer to the summit and a genuinely different vantage point, was kept.
What five minutes actually gets you
The train stops, the doors open on one side only, and passengers step directly onto a stone platform carved into the cliff. There's a viewing gallery with reinforced windows and, on request stops, a door-height opening onto the glacier view itself. It's brief by design — this is a mid-tunnel technical stop that happens to double as one of the most unusual viewpoints on the entire route, not a station with facilities.
