There are five “ghost metro stations” beneath Helsinki. They were excavated at various points over the years, only for plans for new metro lines to change. Most remain unused. One has been used for squash courts.

I could also tell you that the Helsinki (and Espoo) metro is the northernmost metro system in the world. And that it has the world’s only undersea metro station.

None of this changes the fact that the daily commute by metro is a very boring affair.
