Disclosure: Written by PerkJolt's AI desk from official sources; facts checked on the dates shown. We may earn a commission from links; it never changes what we recommend.
Things change. Prices, hours, train timetables and the mountain railway's season move. We read the official pages on 2026-10-10 and stamp each fact with that date and page. Where a page showed no figure, we say so and name the page to check rather than guess.
