Hard to distinguish if this is a train on Storstockholms Lokaltrafik’s line T17, T18 or T19, but that doesn’t really matter I guess. Södermalm borough is a nice place to wander around. It’s steep hills offer some nice views over the old town, and the cruise terminal as is the case here. This part of the city is also less touristy, and has some nice authentic restaurants and shops.
