Train to Mora....questions ??

You'll likely get some real expert advice John, but I'd be very surprised
if you couldn't just get on the train right at Stockholm Airport, and get
to Mora, possibly via a Stockholm station. I remember that I went direct,
no changes, but I had come in on the ferry from Finland, just after
finishing the Finlandia. My Eurailpass was a good deal that year---
flew to Geneva, did some stuff including Transjurrassien, got the train
all the way to Lahti, including the ferry from Stockholm, then back to
Sweden, thenall the way to the channel to finish the trip with a visit
in England, where the pass didn't apply. But 1st class separate tickets
for all that probably would have cost about 7 times what I paid for
the pass, maybe more. Passes for individual countries, Norway in
particular have also been very good deals.
