Actually, you could model Finland in N (with the wrong track gauge), since the Re460's of the Swiss SBB were sold to the VR.
I used to go to Finland frequently and once was treated to a ride on a special chartered train to a road rally. I used to stay about a block from the Helsinki main station and would spend lots of time on the platforms - great to see the dingy, dark green, worn out trains from Russia pull in - and the strange stares from their railway workers - the only folks around who were not friendly.
A friend and I almost took a side trip to St Petersburg one weekend but instead took the hovercraft to
Estonia.
