Not sure about any cost overruns (increased four times original), but progress is slow."Latvia and Estonia have been criticised for building rail terminals before the railway itself" does that make it more difficult to cancel? Although the "scaling back" comments have a certain resemblance to HS2.

Having travelled from the border where the line from Poland comes into Lithuania up to Tallinn earlier this year, I can vouch for the current route being s-l-o-w (and just 1 passenger train a day on some lines).  Rail Baltica would be a game changer assuming there is a people and freight to have their game changed.

Still not quite as messy and time consuming as the "Basque Y" in Spain which has taken 20+ years and resulted in at least one person getting shot.

IIRC the majority of civils have been competed, but not the track laying, and not the final bit into Bilbao, where passengers will have to change to the metro for a considerable length of time.

Of course the project as approved lost it's most inspirational part, connecting Tallinn in Estonia to Helsinki in Finland by a Russian bypass undersea tunnel under the Gulf of Finland. This was dropped early on due to cost. I suspect if the project was being reconsidered afresh now the dismissal of this might not have been so quickly decided.
