Going from Norrmalmstorg to Djurgarden you can use the museum tram line, Djurgardslinjen. On a normal public transportation pass you go by an old tram from the town out on the Djurgarden island.
When you get to Djurgarden I would recommend a visit on Skansen and Grona Lund.
Stockholm has one tram line running from Norrmalmstorg to Djurgarden. The former Tram services ceased to run in the sixties when the country changed to right-hand drive, but this particular line was restored and is run by a voluntary organisation. A fun way to travel if you are heading to Djurgarden!
Although there is an excllent bus service in Stockholm - easily used - it's worth a trip on the old tram along the harbour front to either the Grona Lund or Skansen attractions.
There is a really old tram that serves cakes and coffee on board, as well as a few slightly new ones - apparently most of the trams stopped when Sweden moved to driving on the right, but this line survived.
Stockholm has a couple of tram routes, but the only really useful one is route 7. The vintage tram, known as Djurgårdslinjen, passes a lot of attractions but it costs more than other public transport options and the Stockholm Card isn?t valid. Tickets cost SEK 20.
In Stockholm there is only one tramway line left which is operated in summer only. It can take you to various attractions or you can take a special commented tour. Unfortunately, I caught the one in Swedish only.
In Gothenburg there are lots of tramway lines and they are easy to use. The tickets can be bought from the driver.
