Jungfrau Railway and Jungfraujoch Station

The Jungfrau Railway climbs from Kleine Scheidegg to the Jungfraujoch saddle in the Bernese Alps, in the canton of Bern and partly the canton of Valais, Switzerland, and it is reached from Interlaken via Lauterbrunnen or Grindelwald. The project was conceived by the Zurich industrialist Adolf Guyer-Zeller in 1893, who proposed a rack railway tunnelled through the Eiger and the Mönch rather than built on the exposed slopes. Construction began in 1896 and took 16 years, with workers blasting through rock at altitude in difficult conditions and using dynamite and early electric power. Guyer-Zeller died in 1899, before the line was finished, and the plan was modified, ending at the Jungfraujoch rather than the summit of the Jungfrau as originally intended. The railway opened to the Jungfraujoch station on 1 August 1912, at an altitude of about 3,454 metres, making it the highest railway station in Europe. The line runs largely inside the mountain, with intermediate stops that allow passengers to look out through windows cut into the Eiger north face. At the top, the Jungfraujoch complex includes the Sphinx Observatory, added in 1937 for scientific research, along with tunnels cut into the glacier, a viewing terrace and exhibits about the railway's construction. The route and its structures reflect the engineering ambition of the late 19th and early 20th centuries and remain in use under the Jungfrau Railways, which continues to maintain the track and upgrade the stations. A return ticket from Interlaken Ost costs about CHF 261 in summer, and summit facilities generally operate from roughly 9:00AM to 5:00PM. The journey is long and high-altitude, so visitors should plan a full day, dress for cold and bright conditions, and check the weather before travelling because visibility can change quickly. The site is both a historic engineering monument and a popular tourist destination, and its preservation depends on continuous operation and maintenance.
