I wonder if there's still a way of getting into mainland Russia (not the Kaliningrad exclave) from the EU by rail.
- Travelling via Ukraine is out of question due to multiple reasons.
- Travelling via Belarus is out of question, because 3rd party nationals are not allowed to cross the Belarus-Russia land border (that means by train, car, bus or on foot; flying from Minsk to Moscow is okay for foreigners since May 2017).
- AFAIK, services from Finland have been suspended.
How about Estonia and Latvia? Are there any passenger rail services crossing the border into Russia?
