What is the most beautiful train station in Europe?

Probably Antwerp Centraal made the biggest impression on me, combining the grandiose XIXth century building and shed with the impressive triple-level layout.

I also like those massive modern Clatrava arches like Liège-Guillemins, with the glass throwing colorfoul shade patches on the platforms. Belgium really has a contrast between some beautiful new or rebuilt stations and many horrendous old ones.

I also liked some of the massive London termini I recently discovered : King’s Cross, Paddington and of course St Pancras, akin to (but cleaner than) Paris Nord and Austerlitz.
