A note about trains in sweden. You can take all you can carry onto the train at once... if there's room... at the conductors discretion... So don't bet on it. Friday and Sunday afternoons and evenings the trains are packed.
On the main buses "Swebus" you can't take a bike
afaik
oh, and welcome!
p.s... imho waterproof socks are pretty useless for riding in the rain. I save them for changing into at camp
