View of the waiting room at Stockholm's Central Train Station.  There is a McDonalds there, which can be a cheap alternative to local eateries once in a while.  The fastest way to get from the airport to the train station is by taking the Arlanda Express (second and third pictures), an ultra modern, nicely appointed high-speed train that makes the trip in 20 minutes and departs every ten (cost is Kr 240 or about $44 for a one way ticket).
