Here's the famous Jungfrau train that can either drop you off half way up the mountain (for skiing) or take you (for a pretty steep extra fee) up to the top of the Jungfrau (or "Top of Europe"). Either way, the train ride is spectacular.
The observatory in Jungfraujoch, Switzerland. It is the terminal of a cog railway through the Eiger and Monch.
"The Top of Europe". The Jungfraujoch in Switzerland. The highest train station in the world.
