I want to get to Moscow from Sheremetyevo airport using public transportation. I understand that the best way to do this is to take the Aeroexpress train to Belorussky Rail terminal in Moscow, then take a metro train from Belorusskaya metro station.
What no one seems to mention is how exactly do you transfer from Belorussky rail terminal to Belorusskaya metro station? Are they the same station? Are they physically connected, or must you exit the rail terminal and find the metro station?
This is a very important point that every single online guide glosses over as if I should know this.
