Hell the replies and quote tweets connected with this are giving me some serious "Fernweh" (great German word - opposite of homesickness)

Here follows a thread of the suggested trips / places to visit I now have this urge to do - once that's possible again... https://twitter.com/jonworth/status/1247087041122373637

Stations to visit
Gdańsk Główny - thanks @StefanHechl
And I still have not stopped at @CamburgBahnhof

Routes to travel
Bilbao - Gijon - thanks @QuijoteMike
Glasgow - Fort William/Mallaig - thanks @iamthebaritone & @TommasoMarrone
St Anton-Innsbruck thanks @geoffuptonNZ (only done this one at night before)

Zabreh na Morave - Jesenik - thanks @Dounreay262
Dublin - Galway - thanks @shaneheneghan
Béziers - Clermond-Ferrand - thanks @politic_animal
Clermont-Ferrand - Nîmes (Cévenol) - thanks @michelgellyp

The last two ought to be doable together

And ones that have been on my own list for some time...
Flåmsbana
Reggio Calabria - Taranto
Ferrovia Circumetnea
Gdynia Główna - Hel
anything to Kraków as I've still never been
Ankara - Tehran (via Lake Van - it might be some time before I can do this one!)

And some day I will travel by train in as well, and further in than then little bit around Beijing that I have seen...

Keep the suggestions coming!

Oh and the Pyhrnbahn too... https://de.wikipedia.org/wiki/Pyhrnbahn
